Adaptive Discretization for Episodic Reinforcement Learning in Metric Spaces
Sean R. Sinclair, Siddhartha Banerjee, Christina Lee Yu
We present an efficient algorithm for model-free episodic reinforcement learning on large (potentially continuous) state-action spaces. Our algorithm is based on a novel -learni…

Robust Max Entrywise Error Bounds for Tensor Estimation from Sparse Observations via Similarity Based Collaborative Filtering
Devavrat Shah, Christina Lee Yu
Consider the task of estimating a 3-order tensor from noisy observations of randomly chosen entries in the sparse regime. We introduce a similarity based coll…
