Proud that Qi will present in 2D human pose estimation #HPE at #CVsports @cvprconference.bsky.social how his pose prior-guided refinement approach based on Neural Distance Fields,
polar coordinate representation and its metric, tackles data scarcity of long-jump videos

How can knowledge from easier tasks be transferred to complex tasks while the robot learns tasks relationships? How can it discover new learnable subgoals for more complex tasks? How can human demonstrations be beneficial to an active learning robot?
