New bigAI blog post! @_andrewlevy discusses Hierarchical Actor-Critic (HAC), a new Hierarchical RL algorithm that helps agents more efficiently learn hierarchical policies. Results include the first 3-level agents in continuous domains. Blog Link: bigai.cs.brown.edu/2019/09/03/hac…

New bigAI blog post from @SeungchanKim2! Can we make DQN learn stably without a separate target network? DeepMellow is an alternative deep Q-learning algorithm that uses a new softmax operator, Mellowmax, which removes the need for a target network. seungchan-kim.com/2019/08/12/dee…
