Multi-task and multi-kernel Gaussian process dynamical systems

Highlights:

• We propose a novel method for rectifying damaged motion sequences in an unsupervised manner.

• Our method obviates the need for complete training sequences.

• We take advantage of the sequential nature of the data, the redundancy among repetitions and across different tasks.

• We have devised efficient variational Bayesian inference.

• We have empirically evaluated on one robotic and two motion capture datasets.
