Oral presentations at CVPR and ICML 2021Papers on unsupervised multi-source domain adaptation without source data at CVPR 2021, and on cross-domain imitation learning from observations at ICML 2021
1. The paper Unsupervised Multi-source Domain Adaptation Without Access to Source Data, accepted as oral in CVPR 2021, proposes the Data frEe multi-sourCe unsupervISed domain adaptatiON (DECISION), which identifies the optimal blend of source models with no source data to generate the target model by optimizing a carefully designed unsupervised loss. Under intuitive assumptions, it also establishes theoretical guarantees on the performance of the target model which shows that it is consistently at least as good as deploying the single best source model, thus, minimizing negative transfer.

2. The paper Cross-Domain Imitation from Observations, accepted as a long paper in ICML 2021, proposes an approach to learn policies from a limited number of expert demonstrations obtained from a domain that is different from the agent domain, where the discrepancies could include differing dynamics, viewpoints, or morphology. This work is done in collaboration between UCR and MERL (Mitsubishi Electric Research Laboratories).
