Performance comparison of feature reduction techniques in-terms of compactness, computation time and accuracy

The growth of technologies has led to connection of various devices to the internet. The devices communicate through internet to query the state or information associated with them. These systems require to do real time decision making from the data acquired. In such systems it is important for the learning model to provide faster processing of the data. Large dimension of features makes it a difficult task. Feature reduction is a decisive aspect used in machine learning for dimensionality reduction of data and performance improvement of models. This paper provides a comparative study on the performance of the various feature reduction techniques.
