Feature Selection

Feature Selection in Data Mining

In Machine Learning and statistics, feature selection, also known as the variable selection is the operation of specifying a division of applicable features for apply in form of the model formation. The center basis after operating an element collection approach so as to the data hold a number attributes. It is an algorithm can be seen as the grouping of a search procedure for proposes original attribute subsets, along with...

Semi Supervised Learning Algorithms

Semi-Supervised Learning Models

Semi-Supervised is a category of the Machine Learning approaches and create to control of labeled or unlabeled data for instructions, typically small number of labeled data within a long number of unlabeled data. Semi-Supervised learning fall between unsupervised and supervised knowledge. This approach can be used for traffic identification or classification. This capability suggests traffic classification methods. It depends on single precede information to order...

Ensemble Learning approach in Data Mining

In our day to day life, when crucial decisions are made in a meeting, a voting among the members present in the meeting is conducted when the opinions of the members conflict with each other. This principle of “voting” can be applied to data mining also. In the voting scheme, when classifiers are combined, the class assigned to a test instance will be the one...
