Witryna17 maj 2016 · Introduction. During imitative behavior, the perspective from which an action is viewed affects the transfer of sensory information between the model and imitator (Sambrook, 1998; Meltzoff, 2005).Several imitation studies have reported that sensory information available from the first-person perspective (i.e., as if the imitator … Witrynaa mechanism for learning policies from observation alone, where the expert demonstrations can originate in a domain which is different from the agent domain and access to the expert is limited.

In this thesis, we decompose the imitation from observa-tion problem into two main components: (1) perception of the demonstration, and (2) learning an autonomous control policy.

Learning from observation (LfO) is the problem of learning a policy from a set of state-only expert demonstrations. The goal of LfO is to eventually enable agents to learn by observing humans or other robots. …

WitrynaModel. Our imitation-from-observation algorithm is based on learning a context translation model that can convert a demonstration from one context (e.g., a third person viewpoint and a human demonstrator) to another context (e.g., a first person viewpoint and a robot). By training a model to perform this conversion, we acquire a feature ... Witryna17 mar 2024 · In this paper, we present tractable solutions by formulating imitation learning as minimization of the Sinkhorn distance between occupancy measures. The formulation combines the valuable properties of optimal transport metrics in comparing non-overlapping distributions with a cosine distance cost defined in an adversarially …
