Acoustic Feature Selection with Fuzzy Clustering, Self Organizing Maps and Psychiatric Assessments [chapter]

Olga Kamińska, Katarzyna Kaczmarek-Majer, Olgierd Hryniewicz
2020 Communications in Computer and Information Science  
Acoustic features about phone calls are promising markers for prediction of bipolar disorder episodes.  ...  We start from the recursive feature elimination, then two alternative approaches to clustering (fuzzy clustering and self organizing maps) are performed.  ...  Important feature of the self-organizing maps is the preservation of neighborhood between the clusters in the two-dimensional space.  ...
