Development of New Hybrid Admission Decision Prediction Models Using Support Vector Machines Combined with Feature Selection

Support Vector Machines with Evolutionary Feature Selection for Default Prediction

Predicting default probabilities is at the core of credit risk management and is becoming more and more important for banks in order to measure their client’s degree of risk, and for firms to operate successfully. The SVM with evolutionary feature selection is applied to the CreditReform database. We use classical methods such as discriminan analysis (DA), logit and probit models as benchmark O...

Feature selection using support vector machines

Text categorization is the task of classifying natural language documents into a set of predefined categories. Documents are typically represented by sparse vectors under the vector space model, where each word in the vocabulary is mapped to one coordinate axis and its occurrence in the document gives rise to one nonzero component in the vector representing that document. When training classifi...

Feature Selection Using Linear Support Vector Machines

Feature Subset Selection for Hot Method Prediction using Genetic Algorithm wrapped with Support Vector Machines

Problem statement: All compilers have simple profiling-based heuristics to identify and predict program hot methods and also to make optimization decisions. The major challenge in the profile-based optimization is addressing the problem of overhead. The aim of this work is to perform feature subset selection using Genetic Algorithms (GA) to improve and refine the machine learnt static hot metho...

Analytic Feature Selection for Support Vector Machines

Support vector machines (SVMs) rely on the inherent geometry of a data set to classify training data. Because of this, we believe SVMs are an excellent candidate to guide the development of an analytic feature selection algorithm, as opposed to the more commonly used heuristic methods. We propose a filter-based feature selection algorithm based on the inherent geometry of a feature set. Through...
