Understanding, defining and using knowledge can be based on a number of many approaches, such as the synthesis of Knowledge Management Systems, Knowledge Agents, Knowledge Discovery and Data Mining, Organizational Semantic Webs. Knowledge is based on the accumulation of facts, procedural rules...

Stocks' returns are moved by many risk factors. Thematic stock indices try to represent these factors but are limited by the fact that risk factors are not directly observable. This paper shows a method to uncover hidden risk factors through text analysis. It applies the dynamic variant of the...

In this very first paper of a series of forthcoming research papers of ours, which we propose to bring out in near future regarding the detailed statistical and mathematical analysis of the financial resources and the budget of the Bangalore Municipal Corporation (more appropriately now called...

We discuss the results of the statistical tolerance test of the General Administration Management component of the Capital Expenditure of the Bangalore Municipal Corporation which carries ahead our two previous connected studies (A. Sathyavathi (2023(a)), Analysis of the General Administration...

In continuation of our previous study (A. Sathyavathi (2023). Analysis of the General Administration Management Expenditure of the Bangalore Municipal Corporation https://www.ssrn.com/abstract=4403863 ; http://dx.doi.org/10.2139/ssrn.4403863 ) we propose to further analyze the sample of the...

Voting features based classifiers, shortly VFC, have been shown to perform well on most real-world data sets. They are robust to irrelevant features and missing feature values. In this paper, we introduce an extension to VFC, called voting features based classifier with feature construction,...

Recent financial crises and especially large corporate bankruptcies, have led bank managements and financial authorities to follow and monitor both financial and real sector risks, and to focus on firm failures. Bank of International Settlements, has therefore, taken the decision to include the...

One climate related phenomenon could affect many more. The direct costs associated to climate related factors pass to a number of other climate related costs through the indirect economic consequences of climate change. In this paper we propose a mathematical model which aims to provide...

Local (perturbation) methods compute solutions in one point and tend to deliver far lower accuracy levels than global solution methods. We develop a hybrid method that solves for some policy functions locally (using a perturbation method) and that solves for the other policy functions globally...
