Authors:E.P. Ephzibah, R. Sujatha, Jyotir Moy Chatterjee Pages: 1 - 14 Abstract: Blockchain is a technology that supports secured transaction in a public distributed database. It maintains a peer-to-peer network where a transaction cannot be modified or tampered by unauthenticated users. It provides a safe message transfer from a sender to a receiver. Job recommendation is an online system that provides a mapping between the job seeker and the employer. This paper proposes a public blockchain of job recommendations based on incremental hashing. The examinations show that this blockchain job recommendation provides process integrity, traceability, security, high levels of transparency, drastic reduction in operational cost and high standard and systematic. The system has two stages. Firstly, using blockchain technology, the authenticated data is fetched. Secondly, a classification model using adaptive neuro-fuzzy inference system is built for mapping the job seeker to the recruiter. This approach proves to be authenticated as well as a smart job recommendation system.

Authors:Nimisha Gupta, Mitul Kumar Ahirwal, Mithilesh Atulkar Pages: 15 - 38 Abstract: In this paper, modelling of human decision making process and comparison among various reinforcement learning (RL) techniques with utility functions has been performed. Iowa gambling task (IGT) is used to collect real time data to understand and model the decision making (DM) process involving uncertainty, risk or ambiguity. Performance of models is evaluated based on their mean square deviation (MSD) value. This helps to predict the probability of the next choice that lead to the selection of the advantageous deck as compared to disadvantageous one. Along with that, the deck selection pattern between male and female with the learning process of the participants were also analysed. By comparing the MSD value of various RL models, it is found that the MSD value of DM model consists of prospect utility (PU)-decay reinforcement learning (DRI) with trial dependent choice (TDC) rule is best.

Authors:Ernest Oseghale Amiens, Ifuero Osad Osamwonyi Pages: 39 - 59 Abstract: We used hidden Markov model (HMM) with single observation to estimate stock prices of selected manufacturing companies from the Nigerian Stock Exchange. Data from 22 November 2013 to 6 July 2018 were partitioned into two datasets for training and testing. Subsequently, the data were differenced, trained, tested and used to forecast closing prices for 60 days for each equity. The HMM was implemented with Matlab. The research revealed closing price prediction accuracy ranging from 3.33% to 96.67% and trade signal precision ranging from 31.67% to 97.67%. Also, the MAE values range from 0.0013 to 34.2867 while the MAPE values are between 0.1498% and 6.0034%. The hypothesis tested revealed that the model is efficient. Similarly, the comparison test conducted revealed the performance of HMM is better than ARIMA and neural network (NN). The research proposes that hidden Markov model be adopted in the exercise of stock price forecasting.

Authors:Moumita Poddar, Tanmoyee Banerjee, Ajitava Raychaudhuri Pages: 60 - 84 Abstract: Borrowing for investment in either physical or human capital promotes growth while that for consumption or debt repayment may lead to so called 'debt-trap' for the households. The present paper probes deeper into the decision-making process of the households regarding choice between these alternative borrowing. The data comes from All India Debt and Investment Survey (NSS 70th round). These methods used are Cragg's Box-Cox double hurdle model and instrumental variable (IV) probit model. Our study shows the decision to borrow for investment purposes depends on such factors as gender, religion, location, education, asset position as well as on the status of financial inclusion of households. The decision to borrow for repayment of existing debt is most prevalent among urban educated households in addition to land-owning rural borrowers. Keywords: institutional borrowing; capital formation; financial inclusion; inequality; potential debt-trap Citation: International Journal of Information and Decision Sciences, Vol. 14, No. 1 (2022) pp. 60 - 84 PubDate: 2022-05-09T23:20:50-05:00 DOI: 10.1504/IJIDS.2022.122720 Issue No:Vol. 14, No. 1 (2022)

Authors:Moumita Poddar, Tanmoyee Banerjee, Ajitava Raychaudhuri Pages: 85 - 96 Abstract: In this article, a test statistic for testing the validity of the Cauchy model based on the informational energy is introduced. Consistency of our test is shown. Also, we show that the distribution of the test statistic does not depend on the location and scale parameters. Through a simulation study, we obtain the critical values of the test statistic and then the power of the test is computed by Monte Carlo method against different alternatives. The performance of the proposed test with some competing tests is compared. Our results show that our test is superior to the classical non-parametric tests and can apply to a testing problem in practice.
