This document summarizes a presentation on offline reinforcement learning. It discusses how offline RL can learn from fixed datasets without further interaction with the environment, which allows for fully off-policy learning. However, offline RL faces challenges from distribution shift between the behavior policy that generated the data and the learned target policy. The document reviews several offline policy evaluation, policy gradient, and deep deterministic policy gradient methods, and also discusses using uncertainty and constraints to address distribution shift in offline deep reinforcement learning.
The document discusses regular expressions and finite automata. It begins by defining regular expressions using operations like concatenation, sum, and star. It then discusses how to interpret regular expressions by defining the language they represent. The document goes on to discuss how finite automata can also represent languages and how regular expressions and automata are equivalent based on the fundamental theorem proved by Kleene in 1951. It provides examples of converting between regular expressions and automata.
Two sentences are tokenized and encoded by a BERT model. The first sentence describes two kids playing with a green crocodile float in a swimming pool. The second sentence describes two kids pushing an inflatable crocodile around in a pool. The tokenized sentences are passed through the BERT model, which outputs the encoded representations of the token sequences.
