Improving depression prediction using a novel feature selection algorithm coupled with context-aware analysis
A multivariate filter, namely MIC (Maximal Information Coefficient)-based minimum Redundancy Maximum Relevance (mRMR), to obtain importance ranking of features.
A wrapper, namely sequential involvement and eliminating redundancy with support vector machine (SIER-SVM), to determine the optimal feature subset.
A function to construct feature vector for each session using context-aware analysis.
A function invoking the 'topicWise_feature_mapping_eachSession.m' to construct feature vector for all the sessions.
A function to merge all types of features, including topic presence, audio features, video features, and semantic features.
