Abstract Since real-world data is often inaccurate and working with fuzzy data and Z-numbers are very important and necessary, in the real world we need to rank and compare data. In this paper, we introduce a new method for ranking Z-numbers. This ranking algorithm is based on centroid point.We evaluate distance between centroid point, and based on this distance, we rank the Z-numbers.We use this method in two practical examples. First in ranking the return on assets of Tehran stock exchange, and second, in ranking of factors affecting the productivity of tourism security.The advantage of this method over conventional fuzzy methods is considering uncertainty, and allocating credit in the opinion of experts to estimate fuzzy parameters.

The Relationship

The purpose of this paper is to investigate the relationship between firm’s liquidity and profitability; and to find out the effects of different components of liquidity on firms’ profitability.The relationship between liquidity and firms’ profitability is empirically examined by collecting the data of 50 listed firms of Karachi Stock Exchange, Pakistan. Panel data has been collected from secondary sources for the year 2007 to 2011 .Net operating income and Return on assets are used measure of firm’s profitability. Liquidity of the firm is measured by using cash gap in days and current ratio. Firm size measured by net sales, total assets and market capitalization .The study applies regression analysis to determine factors affecting profitability. Incremental tests are carried out to see the importance of individual variables in the model.The results of correlation and regression analysis showed that there is a significant negative relationship between cash gap and return on assets while current ratio has significant positive relationship with profitability. Results further indicate that log of sales and log of total assets has positive significant relationship with profitability. The findings of this study are based on firms listed on the Karachi Stock Exchange (KSE). Hence, the results cannot be generalizable to those firms which are not listed on Karachi stock exchange.

Smoothing time series allows removing noise. Moving averages are used in finance to smooth stock price series and forecast trend direction. We propose optimised custom moving average that is the most suitable for stock time series smoothing. Suitability criteria are defined by smoothness and accuracy. Previous research focused only on one of the two criteria in isolation. We define this as multi-criteria Pareto optimisation problem and compare the proposed method to the five most popular moving average methods on synthetic and real world stock data. The comparison was performed using unseen data. The new method outperforms other methods in 99.5% of cases on synthetic and in 91% on real world data. The method allows better time series smoothing with the same level of accuracy as traditional methods, or better accuracy with the same smoothness. Weights optimised on one stock are very similar to weights optimised for any other stock and can be used interchangeably. Traders can use the new method to detect trends earlier and increase the profitability of their strategies. The concept is also applicable to sensors, weather forecasting, and traffic prediction where both the smoothness and accuracy of the filtered signal are important.

Finding a determinant of profitability has become one of the most popular topics in banking research. Previous research has identified many factors that significantly influence bank profitability. There are also many studies that measure the effectiveness of sharia banking globally, but few analyze the profitability issues of sharia banks. This study aims to analyze the impact of factors affecting profitability in Islamic Banks listed on the Indonesia Stock Exchange. The method used is multiple linear regression analysis. The variables are return on assets as dependent variable and murabahah, musyarakah, mudharabah, branch office, cash office, and Automatic Teller Machine as independent variable. This study found that funding factors such as murabaha, musharaka and conventional and electronic networking factors such as Branch Office, Cash Office, and ATM had positive and significant impact on profitablity of Sharia Bank, while mudharabah had a negative and significant influence on profitablitas Sharia Bank. Sub-Branch Offices also had a negative but insignificant effect on the profitability of Sharia Banks. This result indicated that income on management became the most dominant income in generating profit of sharia banking. However, the management of funds could not work if not supported by Islamic banking channeling tools.

Unsupervised disentangled representation learning is one of the foundational methods to learn interpretable factors in the data. Existing learning methods are based on the assumption that disentangled factors are mutually independent and incorporate this assumption with the evidence lower bound. However, our experiment reveals that factors in real-world data tend to be pairwise independent. Accordingly, we propose a new method based on a pairwise independence assumption to learn the disentangled representation. The evidence lower bound implicitly encourages mutual independence of latent codes so it is too strong for our assumption. Therefore, we introduce another lower bound in our method. Extensive experiments show that our proposed method gives competitive performances as compared with other state-of-the-art methods.
