In particular, FORK includes a neural network that forecasts the next state given the current state and current action, called system network; and a neural network that forecasts the\r\nreward given a (state, action) pair, called reward network. With the system network and reward network, FORK can forecast the next state and consider the value of the next state when improving the policy.","description_state":"present","introduced_year":null,"introduced_by":{"title":"FORK: A Forward-Looking Actor For Model-Free Reinforcement Learning","paper":"/paper/fork-a-forward-looking-actor-for-model-free-1","first_author":"Honghao Wei","n_authors":2,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/fork-a-forward-looking-actor-for-model-free-1"},"source":{"url":"https://arxiv.org/abs/2010.01652v3","title":"FORK: A Forward-Looking Actor For Model-Free Reinforcement Learning","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Reinforcement Learning","area_id":"reinforcement-learning","collection":"Actor-Critic Algorithms","url":"/methods/category/actor-critic-algorithms","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/fork-a-forward-looking-actor-for-model-free-1","title":"FORK: A Forward-Looking Actor For Model-Free Reinforcement Learning","date":"2020-10-04","arxiv_id":"2010.01652","n_code_links":2,"syntology":null}],"papers_shown":1,"tasks":[{"task":null,"name":"GPU","papers":1},{"task":"/task/mujoco","name":"MuJoCo","papers":1},{"task":"/task/reinforcement-learning","name":"Reinforcement Learning","papers":1},{"task":"/task/reinforcement-learning-1","name":"Reinforcement Learning (RL)","papers":1},{"task":"/task/reinforcement-learning-2","name":"reinforcement-learning","papers":1}],"tasks_shown":5,"n_tasks":5,"usage_by_year":[{"year":"2020","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/fork"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
