Special Issue on Computational Intelligence in Data mining

When we attempt to solve real-world problems, like extracting knowledge from large amount of data, we realize that they are typically ill-defined systems, difficult to model and with large-scale solution spaces. In these cases, precise models are impractical, too expensive, or non-existent. Furthermore, the relevant available information is usually in the form of empirical prior knowledge and i...

Special Issue on Computational Intelligence in Data mining

In our society the amount of data doubles almost every year. Hence, there is an urgent need for a new generation of computationally intelligent techniques and tools to assist humans in extracting useful information (knowledge) from the rapidly growing volume of data. When we attempt to solve real-world problems, like extracting knowledge from large amount of data, we realize that they are typic...

The main aim of this study is to develop part-of-speech tagger for Afaan Oromo language. After reviewing literatures on Afaan Oromo grammars and identifying tagset and word categories, the study adopted Hidden Markov Model (HMM) approach and has implemented unigram and bigram models of Viterbi algorithm. Unigram model is used to understand word ambiguity in the language, while bigram model is u...

Special issue on computational finance

Many of the papers in this special issue were initially presented at the 2nd International Workshop on Parallel and Distributed Computing in Finance (PDCoF) held in conjunction with The 23rd International Parallel and Distributed Processing Symposium (IPDPS). The papers were significantly revised, extended for consideration in this special issue. The purpose of this special issue is to bring to...
