Finding good policies in average-reward Markov Decision Processes without prior knowledge
Reinforcement learning (RL) is a paradigm in which an agent interacts with its environment, modeled as a Markov Decision Process (MDP), by taking actions and observing rewards.
Vision-Language Navigation with Energy-Based Policy
Existing VLN models are optimized through expert demonstrations by supervised behavioural cloning or incorporating manual reward engineering.

Furthermore, extensive analysis ( 4.3) on Spider2-V demonstrate that these strategies remarkably
OPERA: Automatic Offline Policy Evaluation with Re-weighted Aggregates of Multiple Estimators
Unfortunately, choosing the best OPE algorithm for each task and domain is still unclear.
Integrating Suboptimal Human Knowledge with Hierarchical Reinforcement Learning for Large-Scale Multiagent Systems
While agents' learning is data-driven, sampling from millions
Divide-and-Conquer Posterior Sampling for Denoising Diffusion Priors
Recent advancements in solving Bayesian inverse problems have spotlighted de-noising diffusion models (DDMs) as effective priors. Although these have great potential, DDM priors yield complex posterior distributions that are challenging to sample.
