Semi-Markov kMeans Clustering and Activity Recognition from Body-Worn Sensors

Robards, Matthew; Sunehag, Peter

Description

Subsequence clustering aims to find patterns that appear repeatedly in time series data. We introduce a novel subsequence clustering technique that we call semi-Markov kmeans clustering. The clustering results in ideal examples of the repeating patterns and in labeled segmentations that can be used as training data for sophisticated discriminative methods like max-margin semi-Markov models. We are applying the new clustering technique to activity recognition from body-worn sensors by showing...[Show more]
