“…Since many interactive tasks can naturally be broken down into underlying segments or phases that are then sequenced to achieve suitable behavior, previous works have explored learning HRI from demonstrations using Gaussian Mixture Models (GMMs) or, additionally, Hidden Markov Models (HMMs) with an underlying Mixture of Gaussians structure [3,4,13,14,11,10,15]. However, Hidden Markov Models have limitations in representing transition states.…”
