Machine learning techniques for Dimensionality Reduction and Comparative Lead Investigator: Kashif Javed Lone Institution : University of Azad Jammu and Kashmir E-Mail : insaaftimber@gmail.com Proposal ID : 842 Proposal Description: The accuracy at which the decision support system predicts or classifies the samples is of main concern in several domains especially in the field of medical science. The major problem that raise is the curse of dimensionality few samples but the thousand of features. This makes the problem very complicated. so, taking in view the problem discussed above, we are going 1- To use machine learning dimensionality reduction (feature selection and feature extraction) techniques on Alzheimer disease data (High Dimensional data). 2- We also develop different models to classify Alzheimers patients.
