Classification in data mining involves classifying a set of data instances into predefined classes. Learn more about its types and features with this blog.
One of the problems associated with OVP procedure is great number of regularities in output system in high-dimensional tasks. The new approach for output system structure evaluating is suggested that is based on searching subsystem of small size with possibly better forecasting ability of convex ...

gini index, gini(D) is defined as where pj is the relative frequency of class j in D If a data set D is split on A into two subsets D1 and D2, the gini index gini(D) is defined as Reduction in Impurity: The attribute provides the smallest ginisplit(D) (or the largest ...
Statistical data-mining (DM) and machine learning (ML) are promising tools to assist in the analysis of complex dataset. In recent decades, in the precision of agricultural development, plant phenomics study is crucial for high-throughput phenotyping of local crop cultivars. Therefore, integrated or...
In this paper, we investigate the application and effectiveness of several data mining approaches for electricity market price classification. In addition, we propose a new data model for forming the initial data set for price classification. Simulation results for New York, Ontario, and Alberta ...
Time Series Classification (TSC) is an important and challenging problem in data mining. With the increase of time series data availability, hundreds of TS
In predictive model development, gene expression data is associated with the unique challenge that the number of samples (n) is much smaller than the amount of features (p). This “n ≪ p” property has prevented classification of gene expression
