  • Emotional Human-Machine Conversation Generation Based on Long Short-Term
    • Authors: Xiao Sun; Xiaoqi Peng; Shuai Ding
      Pages: 389 - 397
      Abstract: With the rise in popularity of artificial intelligence, the technology of verbal communication between man and machine has received an increasing amount of attention, but generating a good conversation remains a difficult task. The key factor in human-machine conversation is whether the machine can give good responses that are appropriate not only at the content level (relevant and grammatical) but also at the emotion level (consistent emotional expression). In our paper, we propose a new model based on long short-term memory, which is used to achieve an encoder-decoder framework, and we address the emotional factor of conversation generation by changing the model’s input using a series of input transformations: a sequence without an emotional category, a sequence with an emotional category for the input sentence, and a sequence with an emotional category for the output responses. We perform a comparison between our work and related work and find that we can obtain slightly better results with respect to emotion consistency. Although in terms of content coherence our result is lower than those of related work, in the present stage of research, our method can generally generate emotional responses in order to control and improve the user’s emotion. Our experiment shows that through the introduction of emotional intelligence, our model can generate responses appropriate not only in content but also in emotion.

  • Mood Impact on Automaticity of Performance: Handwriting as Exemplar
    • Authors: Clara Rispler; Gil Luria; Allon Kahana; Sara Rosenblum
      Pages: 398 - 407
      Abstract: The goal of this study was to assess how existing handwriting research can contribute to understanding how moods impact the automatic processing of handwriting performance. We based our hypotheses on extensive research connecting mood with cognitive functions, because handwriting production was shown to be an automated cognitive task impacted by cognitive load. As far as we know, no previous research has examined the direct relationship between affect and handwriting (transcription and text generation when writing by hand). Specifically, evidence exists only for a general relationship between affect and writing (using written words to express ideas or opinions). In this experiment, 62 participants were divided into three mood groups (positive, negative, and neutral). Mood manipulation was conducted according to accepted methods of memory recall and film induction and was evaluated using the PANAS scale. Online measurements of the participants’ handwriting were captured with a tablet and electronic pen. Results showed that the strokes in the negative mood manipulation were shorter in duration and shorter in width and height. The findings presented in this article make a twofold contribution to the cognitive and biologically inspired computational studies: by integrating the study of affect with the study of cognition and by exploring additional objective performance-based evaluation of functional capabilities with the aid of a computerized device. Practical implications are discussed, as are ideas for further research.

  • Evaluating Integration Strategies for Visuo-Haptic Object Recognition
    • Authors: Sibel Toprak; Nicolás Navarro-Guerrero; Stefan Wermter
      Pages: 408 - 425
      Abstract: In computational systems for visuo-haptic object recognition, vision and haptics are often modeled as separate processes. But this is far from what really happens in the human brain, where cross- as well as multimodal interactions take place between the two sensory modalities. Generally, three main principles can be identified as underlying the processing of the visual and haptic object-related stimuli in the brain: (1) hierarchical processing, (2) the divergence of the processing onto substreams for object shape and material perception, and (3) the experience-driven self-organization of the integratory neural circuits. The question arises whether an object recognition system can benefit in terms of performance from adopting these brain-inspired processing principles for the integration of the visual and haptic inputs. To address this, we compare the integration strategy that incorporates all three principles to the two commonly used integration strategies in the literature. We collected data with a NAO robot enhanced with inexpensive contact microphones as tactile sensors. The results of our experiments involving every-day objects indicate that (1) the contact microphones are a good alternative to capturing tactile information and that (2) organizing the processing of the visual and haptic inputs hierarchically and in two pre-processing streams is helpful performance-wise. Nevertheless, further research is needed to effectively quantify the role of each identified principle by itself as well as in combination with others.

  • The Fundamental Code Unit of the Brain: Towards a New Model for Cognitive
    • Authors: Newton Howard; Amir Hussain
      Pages: 426 - 436
      Abstract: This paper discusses the problems arising from the multidisciplinary nature of cognitive research and the need to conceptually unify insights from multiple fields into the phenomena that drive cognition. Specifically, the Fundamental Code Unit (FCU) is proposed as a means to better quantify the intelligent thought process at multiple levels of analysis. From the linguistic and behavioral output, FCU produces to the chemical and physical processes within the brain that drive it. The proposed method efficiently model the most complex decision-making process performed by the brain.

  • Discriminative Deep Belief Network for Indoor Environment Classification
           Using Global Visual Features
    • Authors: Nabila Zrira; Haris Ahmad Khan; El Houssine Bouyakhf
      Pages: 437 - 453
      Abstract: Indoor environment classification, also known as indoor environment recognition, is a highly appreciated perceptual ability in mobile robots. In this paper, we present a novel approach which is centered on biologically inspired methods for recognition and representation of indoor environments. First, global visual features are extracted by using the GIST descriptor, and then we use the subsequent features for training the discriminative deep belief network (DDBN) classifier. DDBN employs a new deep architecture which is based on restricted Boltzmann machines (RBMs) and the joint density model. The back-propagation technique is used over the entire classifier to fine-tune the weights for an optimum classification. The acquired experimental results validate our approach as it performs well both in the real-world and in synthetic datasets and outperforms the Convolution Neural Networks (ConvNets) in terms of computational efficiency.

  • Multiple Attribute Decision-Making Methods Based on the Expected Value and
           the Similarity Measure of Hesitant Neutrosophic Linguistic Numbers
    • Authors: Jun Ye
      Pages: 454 - 463
      Abstract: The existing neutrosophic linguistic decision-making approach uses only one neutrosophic linguistic number (NLN) to express its evaluation value of an attribute in decision making. Sometimes, it may not reflect exactly what decision makers mean due to the ambiguity and indeterminacy of their cognitions to complex decision-making problems. In this situation, decision makers might hesitate among several NLNs to express their opinions. To deal with the issue, this paper defines hesitant neutrosophic linguistic numbers (HNLNs), the expected value of HNLN and proposes the generalized distance and similarity measure between two HNLN sets based on the least common multiple cardinality for HNLNs. Then, multiple attribute decision-making (MADM) methods are established based on the expected value and the similarity measure under a HNLN environment. In the proposed decision-making methods, the evaluation values of alternatives over attributes provided by decision makers are HNLNs, and then all the alternatives are ranked by the expected values of HNLNs and the similarity measure values between each alternative and the ideal alternative (ideal solution) to select the best one. An actual example on the selection problem of manufacturing alternatives is provided to demonstrate the applicability of the developed decision-making approaches. The decision results of manufacturing alternatives and the comparative analysis indicate that the proposed methods are effective and superior to existing ones. The MADM methods based on the expected value and the similarity measure can effectively deal with MADM problems with HNLN information and are more objective and more useful than the existing ones.

  • Extreme Learning Machines for VISualization+R: Mastering Visualization
           with Target Variables
    • Authors: Andrey Gritsenko; Anton Akusok; Stephen Baek; Yoan Miche; Amaury Lendasse
      Pages: 464 - 477
      Abstract: The current paper presents an improvement of the Extreme Learning Machines for VISualization (ELMVIS+) nonlinear dimensionality reduction method. In this improved method, called ELMVIS+R, it is proposed to apply the originally unsupervised ELMVIS+ method for the regression problems, using target values to improve visualization results. It has been shown in previous work that the approach of adding supervised component for classification problems indeed allows to obtain better visualization results. To verify this assumption for regression problems, a set of experiments on several different datasets was performed. The newly proposed method was compared to the ELMVIS+ method and, in most cases, outperformed the original algorithm. Results, presented in this article, prove the general idea that using supervised components (target values) with nonlinear dimensionality reduction method like ELMVIS+ can improve both visual properties and overall accuracy.

  • Simultaneous Feature Selection and Support Vector Machine Optimization
           Using the Grasshopper Optimization Algorithm
    • Authors: Ibrahim Aljarah; Ala’ M. Al-Zoubi; Hossam Faris; Mohammad A. Hassonah; Seyedali Mirjalili; Heba Saadeh
      Pages: 478 - 495
      Abstract: Support vector machine (SVM) is considered to be one of the most powerful learning algorithms and is used for a wide range of real-world applications. The efficiency of SVM algorithm and its performance mainly depends on the kernel type and its parameters. Furthermore, the feature subset selection that is used to train the SVM model is another important factor that has a major influence on it classification accuracy. The feature subset selection is a very important step in machine learning, specially when dealing with high-dimensional data sets. Most of the previous researches handled these important factors separately. In this paper, we propose a hybrid approach based on the Grasshopper optimisation algorithm (GOA), which is a recent algorithm inspired by the biological behavior shown in swarms of grasshoppers. The goal of the proposed approach is to optimize the parameters of the SVM model, and locate the best features subset simultaneously. Eighteen low- and high-dimensional benchmark data sets are used to evaluate the accuracy of the proposed approach. For verification, the proposed approach is compared with seven well-regarded algorithms. Furthermore, the proposed approach is compared with grid search, which is the most popular technique for tuning SVM parameters. The experimental results show that the proposed approach outperforms all of the other techniques in most of the data sets in terms of classification accuracy, while minimizing the number of selected features.

  • D-Intuitionistic Hesitant Fuzzy Sets and their Application in Multiple
           Attribute Decision Making
    • Authors: Xihua Li; Xiaohong Chen
      Pages: 496 - 505
      Abstract: Hesitant fuzzy sets (HFSs) and generalized hesitant fuzzy sets (GHFSs) provide useful tools for uncertain information processing in situations in which decision makers have doubts among several possible membership degrees. In practice, however, decision makers may have a degree of belief for hesitant memberships based on their knowledge and experience. The aim of our study is to propose a new manifestation of uncertain information, called D-intuitionistic hesitant fuzzy sets (D-IHFSs), by combining D numbers and GHFSs. First, arithmetic operations, score functions, and comparison laws related to D-IHFSs are introduced. Next, an extension principle is proposed for the application of aggregation operators of GHFSs to the D-intuitionistic hesitant fuzzy environment. Finally, a decision-making approach based on D-IHFSs is developed. An illustrative example shows the effectiveness and flexibility of D-IHFSs to handle uncertainties, such as fuzziness, hesitation, and incompleteness. D-IHFSs, combining D numbers and GHFSs, improve decision makers’ ability to handle uncertain information.

  • Rank-Adaptive Non-Negative Matrix Factorization
    • Authors: Dong Shan; Xinzheng Xu; Tianming Liang; Shifei Ding
      Pages: 506 - 515
      Abstract: Dimension reduction is a challenge task in data processing, especially in high-dimensional data processing area. Non-negative matrix factorization (NMF), as a classical dimension reduction method, has a contribution to the parts-based representation for the characteristics of non-negative constraints in the NMF algorithm. In this paper, the NMF algorithm is introduced to extract local features for dimension reduction. Considering the problem of which NMF is required to define the number of the decomposition rank manually, we proposed a rank-adaptive NMF algorithm, in which the affinity propagation (AP) clustering algorithm is introduced to determine adaptively the number of the decomposition rank of NMF. Then, the rank-adaptive NMF algorithm is used to extract features for the original image. After that, a low-dimensional representation of the original image is obtained through the projection from the original images to the feature space. Finally, we used extreme learning machine (ELM) and k-nearest neighbor (KNN) as the classifier to classify those low-dimensional feature representations. The experimental results demonstrate that the decomposition rank determined by the AP clustering algorithm can reflect the characteristics of the original data. When it is combined with the classification algorithm ELM or KNN and applied to handwritten character recognition, the proposed method not only reduces the dimension of original images but also performs well in terms of classification accuracy and time consumption. A new rank-adaptive NMF algorithm is proposed based on the AP clustering algorithm and the original NMF algorithm. According to this algorithm, the low-dimensional representation of the original data can be obtained without any prior knowledge. In addition, the proposed rank-adaptive NMF algorithm combined with the ELM and KNN classification algorithms performs well.

  • Anomaly-Based Intrusion Detection Using Extreme Learning Machine and
           Aggregation of Network Traffic Statistics in Probability Space
    • Authors: Buse Gul Atli; Yoan Miche; Aapo Kalliola; Ian Oliver; Silke Holtmanns; Amaury Lendasse
      Abstract: Recently, with the increased use of network communication, the risk of compromising the information has grown immensely. Intrusions have become more sophisticated and few methods can achieve efficient results while the network behavior constantly changes. This paper proposes an intrusion detection system based on modeling distributions of network statistics and Extreme Learning Machine (ELM) to achieve high detection rates of intrusions. The proposed model aggregates the network traffic at the IP subnetwork level and the distribution of statistics are collected for the most frequent IPv4 addresses encountered as destination. The obtained probability distributions are learned by ELM. This model is evaluated on the ISCX-IDS 2012 dataset, which is collected using a real-time testbed. The model is compared against leading approaches using the same dataset. Experimental results show that the presented method achieves an average detection rate of 91% and a misclassification rate of 9%. The experimental results show that our methods significantly improve the performance of the simple ELM despite a trade-off between performance and time complexity. Furthermore, our methods achieve good performance in comparison with the other few state-of-the-art approaches evaluated on the ISCX-IDS 2012 dataset.

  • Outranking Decision-Making Method with Z-Number Cognitive Information
    • Authors: Hong-gang Peng; Jian-qiang Wang
      Abstract: The Z-number provides an adequate and reliable description of cognitive information. The nature of Z-numbers is complex, however, and important issues in Z-number computation remain to be addressed. This study focuses on developing a computationally simple method with Z-numbers to address multicriteria decision-making (MCDM) problems. Processing Z-numbers requires the direct computation of fuzzy and probabilistic uncertainties. We used an effective method to analyze the Z-number construct. Next, we proposed some outranking relations of Z-numbers and defined the dominance degree of discrete Z-numbers. Also, after analyzing the characteristics of elimination and choice translating reality III (ELECTRE III) and qualitative flexible multiple criteria method (QUALIFLEX), we developed an improved outranking method. To demonstrate this method, we provided an illustrative example concerning job-satisfaction evaluation. We further verified the validity of the method by a criteria test and comparative analysis. The results demonstrate that the method can be successfully applied to real-world decision-making problems, and it can identify more reasonable outcomes than previous methods. This study overcomes the high computational complexity in existing Z-number computation frameworks by exploring the pairwise comparison of Z-numbers. The method inherits the merits of the classical outranking method and considers the non-compensability of criteria. Therefore, it has remarkable potential to address practical decision-making problems involving Z-information.

  • Distributed Drone Base Station Positioning for Emergency Cellular Networks
           Using Reinforcement Learning
    • Authors: Paulo V. Klaine; João P. B. Nadas; Richard D. Souza; Muhammad A. Imran
      Abstract: Due to the unpredictability of natural disasters, whenever a catastrophe happens, it is vital that not only emergency rescue teams are prepared, but also that there is a functional communication network infrastructure. Hence, in order to prevent additional losses of human lives, it is crucial that network operators are able to deploy an emergency infrastructure as fast as possible. In this sense, the deployment of an intelligent, mobile, and adaptable network, through the usage of drones—unmanned aerial vehicles—is being considered as one possible alternative for emergency situations. In this paper, an intelligent solution based on reinforcement learning is proposed in order to find the best position of multiple drone small cells (DSCs) in an emergency scenario. The proposed solution’s main goal is to maximize the amount of users covered by the system, while drones are limited by both backhaul and radio access network constraints. Results show that the proposed Q-learning solution largely outperforms all other approaches with respect to all metrics considered. Hence, intelligent DSCs are considered a good alternative in order to enable the rapid and efficient deployment of an emergency communication network.

  • A Novel Cognitively Inspired State Transition Algorithm for Solving the
           Linear Bi-Level Programming Problem
    • Authors: Zhaoke Huang; Chunhua Yang; Xiaojun Zhou; Weihua Gui
      Abstract: Linear bi-level programming (LBLP) is a useful tool for modeling decentralized decision-making problems. It has two-level (upper-level and lower-level) objectives. Many studies have shown that the LBLP problem is NP-hard, meaning it is difficult to find a global solution in polynomial time. In this paper, we present a novel cognitively inspired computing method based on the state transition algorithm (STA) to obtain an approximate optimal solution for the LBLP problem in polynomial time. The proposed method is applied to a supply chain model that fits the definition of an LBLP problem. The experimental results indicate that the proposed method is more efficient in terms of solution accuracy through a comparison to other metaheuristic-based methods using four problems from the literature in addition to the supply chain distribution model. In this study, a cognitively inspired STA-based method was proposed for the LBLP problem. In the future, we expect to extent the proposed method for linear multi-level programming problems.

  • Conditional Random Mapping for Effective ELM Feature Representation
    • Authors: Cheng Li; Chenwei Deng; Shichao Zhou; Baojun Zhao; Guang-Bin Huang
      Abstract: Extreme learning machine (ELM) has been extensively studied, due to its fast training and good generalization. Unfortunately, the existing ELM-based feature representation methods are uncompetitive with state-of-the-art deep neural networks (DNNs) when conducting some complex visual recognition tasks. This weakness is mainly caused by two critical defects: (1) random feature mappings (RFM) by ad hoc probability distribution is unable to well project various input data into discriminative feature spaces; (2) in the ELM-based hierarchical architectures, features from previous layer are scattered via RFM in the current layer, which leads to abstracting higher level features ineffectively. To address these issues, we aim to take advantage of label information for optimizing random mapping in the ELM, utilizing an efficient label alignment metric to learn a conditional random feature mapping (CRFM) in a supervised manner. Moreover, we proposed a new CRFM-based single-layer ELM (CELM) and then extended CELM to the supervised multi-layer learning architecture (ML-CELM). Extensive experiments on various widely used datasets demonstrate our approach is more effective than original ELM-based and other existing DNN feature representation methods with rapid training/testing speed. The proposed CELM and ML-CELM are able to achieve discriminative and robust feature representation, and have shown superiority in various simulations in terms of generalization and speed.

  • A Nature-Inspired Hybrid Technique for Interference Reduction in Cognitive
           Radio Networks
    • Authors: Atif Elahi; Ijaz Mansoor Qureshi; Noor Gul; M. Sajjad Khan; Hayat Ullah
      Abstract: Orthogonal frequency division multiplexing, a multicarrier method, is so far the best potential candidate for the physical layer of cognitive radio system. It has the ability to efficiently utilize the spectrum holes, contiguous or non-contiguous, and accordingly make an effective use of the natural resources. On the other hand, one of the major drawbacks is its high side-lobes that result in excessive out-of-band radiation. This out-of-band radiation causes significant interference to the nearby users, including the licensed or un-licensed. Existing techniques found in the literature for the reduction of out-of-band radiation have been compared with our proposed technique. In this paper, a hybrid technique is developed to reduce the out-of-band radiation by a cancelation carrier method using nature-inspired algorithm, known as cuckoo search algorithm. It has been widely used in different fields of engineering, for solving the problem related to optimization, especially global optimization. The generalized side-lobe canceller, which is the simplest version of linearly constraint minimum variance, coverts the constraint minimization problem into an unconstraint one. Simulation results depicted that with the proposed technique, significant improvement in interference reduction is achieved.

  • A Generative Model of Cognitive State from Task and Eye Movements
    • Authors: W. Joseph MacInnes; Amelia R. Hunt; Alasdair D. F. Clarke; Michael D. Dodd
      Abstract: The early eye tracking studies of Yarbus provided descriptive evidence that an observer’s task influences patterns of eye movements, leading to the tantalizing prospect that an observer’s intentions could be inferred from their saccade behavior. We investigate the predictive value of task and eye movement properties by creating a computational cognitive model of saccade selection based on instructed task and internal cognitive state using a Dynamic Bayesian Network (DBN). Understanding how humans generate saccades under different conditions and cognitive sets links recent work on salience models of low-level vision with higher level cognitive goals. This model provides a Bayesian, cognitive approach to top-down transitions in attentional set in pre-frontal areas along with vector-based saccade generation from the superior colliculus. Our approach is to begin with eye movement data that has previously been shown to differ across task. We first present an analysis of the extent to which individual saccadic features are diagnostic of an observer’s task. Second, we use those features to infer an underlying cognitive state that potentially differs from the instructed task. Finally, we demonstrate how changes of cognitive state over time can be incorporated into a generative model of eye movement vectors without resorting to an external decision homunculus. Internal cognitive state frees the model from the assumption that instructed task is the only factor influencing observers’ saccadic behavior. While the inclusion of hidden temporal state does not improve the classification accuracy of the model, it does allow accurate prediction of saccadic sequence results observed in search paradigms. Given the generative nature of this model, it is capable of saccadic simulation in real time. We demonstrated that the properties from its generated saccadic vectors closely match those of human observers given a particular task and cognitive state. Many current models of vision focus entirely on bottom-up salience to produce estimates of spatial “areas of interest” within a visual scene. While a few recent models do add top-down knowledge and task information, we believe our contribution is important in three key ways. First, we incorporate task as learned attentional sets that are capable of self-transition given only information available to the visual system. This matches influential theories of bias signals by (Miller and Cohen Annu Rev Neurosci 24:167–202, 2001) and implements selection of state without simply shifting the decision to an external homunculus. Second, our model is generative and capable of predicting sequence artifacts in saccade generation like those found in visual search. Third, our model generates relative saccadic vector information as opposed to absolute spatial coordinates. This matches more closely the internal saccadic representations as they are generated in the superior colliculus.

  • A Projection-Based Outranking Method with Multi-Hesitant Fuzzy Linguistic
           Term Sets for Hotel Location Selection
    • Authors: Pu Ji; Hong-Yu Zhang; Jian-Qiang Wang
      Abstract: Keen competition drives hotel companies to enhance their position. One way to do this is to select a proper hotel location. However, hotel location selection is a complex problem. This study establishes a multi-criteria hotel location selection method. In this method, cognitive information is depicted by multi-hesitant fuzzy linguistic term sets (MHFLTSs). Moreover, the method considers the non-compensation of criteria. It introduces the elimination and choice translating reality (ELECTRE) method. Notably, the method utilizes projection to define concordance and discordance indices. A case study and comparative study are performed in this study. They exhibit the feasibility of the method. Results of the studies show that the method can solve such problems, and they reveal the method’s advantages. One theoretical contribution lies in the characterization of cognitive information. MHFLTSs can handle vacillation of decision-makers caused by their complex cognition, and they express both conformity and divergence of opinions during cognitive processes. Our method has the advantages of the ELECTRE method. In addition, the ELECTRE method is improved by introducing the projection. The proposed method is promising in hotel location selection. Moreover, it is a potential option to address cognitive computation.

  • An Insight into Bio-inspired and Evolutionary Algorithms for Global
           Optimization: Review, Analysis, and Lessons Learnt over a Decade of
    • Authors: Daniel Molina; Antonio LaTorre; Francisco Herrera
      Abstract: Over the recent years, continuous optimization has significantly evolved to become the mature research field it is nowadays. Through this process, evolutionary algorithms had an important role, as they are able to obtain good results with limited resources. Among them, bio-inspired algorithms, which mimic cooperative and competitive behaviors observed in animals, are a very active field, with more proposals every year. This increment in the number of optimization algorithms is apparent in the many competitions held at corresponding special sessions in the last 10 years. In these competitions, several algorithms or ideas have become points of reference, and used as starting points for more advanced algorithms in following competitions. In this paper, we have obtained, for different real-parameter competitions, their benchmarks, participants, and winners (from the competitions’ website) and we review the most relevant algorithms and techniques, presenting the trajectory they have followed over the last years and how some of these works have deeply influenced the top performing algorithms of today. The aim is to be both a useful reference for researchers new to this interesting research topic and a useful guide for current researchers in the field. We have observed that there are several algorithms, like the Covariance Matrix Adaptation Evolution Strategy (CMA-ES), the Success-History based Adaptive Differential Evolution with Linear Population Size Reduction (L-SHADE), Mean-Variance Mapping Optimization (MVMO), and Multiple Offspring Sampling (MOS), which have obtained a strong influence over other algorithms. We have also suggested several techniques that are being widely adopted among the winning proposals, and that could be used for more competitive algorithms. Global optimization is a mature research field in continuous improvement, and the history of competitions provides useful information about the past that can help us to learn how to go forward in the future.

  • A Joint Unsupervised Cross-Domain Model via Scalable Discriminative
           Extreme Learning Machine
    • Authors: Boyang Zhang; Yingyi Liu; Haiwen Yuan; Lingjie Sun; Zhao Ma
      Abstract: Extreme learning machine (ELM) is a well-known cognitive model, that has been extended to cross-domain tasks. Nonetheless, most existing paradigms that are based on ELM either concern about a case in which a specific number of instances are labelled in the target domain or a learner is trained without sufficient capacity to eliminate the gap between domains. To cope with the scenario in which there are no target labels and to acquire a better adaptive learner, we propose a joint unsupervised cross-domain model via scalable discriminative ELM, which is abbreviated as JUC-SDELM. Within the framework, the scalable factor is integrated into discriminative ELM (DELM) to adjust the output margin, which strengthens the discriminative capacity of the ELM classifier. In addition, we follow the basic strategy of joint distribution adaptation (JDA) to align the subspaces generated by JUC-SDELM in terms of their statistics. The discrepancy across domains is alleviated after a few iterations. Moreover, a metric on the outputs of ELM is utilized to filter unreliable pseudo labels in the target domain, with the aim of eliminating the negative transfer effect. Results are obtained by comparing JUC-SDELM with state-of-the-art baseline methods on 16 cross-domain benchmarks that were constructed based on three combined datasets. Likewise, the outcomes in terms of key parameters are also examined. According to the experiments, our proposed model achieves competitive overall performance.
