used to hybridise DAgger by Vlachos and Clark (2014), referred to later as V-DAgger (Goodman et al. Some structured prediction tasks we know. 2011 ) LoLS ¶ Imitation learning involves training a driving policy to mimic the actions of an expert driver (a policy is an agent that takes in observations of the environment and outputs vehicle controls). Combining Imitation Learning and Reinforcement Learning Using DQfD. arXiv_RO. ∙ berkeley college ∙ 0 ∙ share . One approach to Imitation Learning is Behavior Cloning, in which a robot observes a supervisor and infers a control policy. On-Policy Imitation Learning Online imitation learning algorithms that directly learn re-active policies from a supervisor were recently popularized with DAgger in (Ross et al.,2011b). 2011 ) LoLS ¶ Inverse Reinforcement Learning An alternative to imitation learning: Use demonstrations to learn a reward function. 2.2.

Imitation Learning (IL) and Reinforcement Learning (RL) are often introduced as similar, but separate problems. Deep Imitation Learning of Sequential Fabric Smoothing Policies. DAgger is an iterative Requirements. The agent only learns to control the steer [-1, 1], the speed is computed automatically in gym_torcs.TorcsEnv.
For more detail, please see the associated thesis document here or the associated GitHub repository here.. Imitation learning is a technique that aims to learn a policy from a collection of state-action pairs as demonstrated by an expert (human, optimal controller, path-planner, etc. a human driver) in the real world or a simulated environment and then used to train the driving policy. ). 2019-03-11 Michael Kelly, Chelsea Sidrane, Katherine Driggs-Campbell, Mykel J.

Imitation Learning by Coaching He He1, Hal Daume III´ 1 and Jason Eisner2 1University of Maryland, College Park 2Johns Hopkins University Introduction I Imitation learning by classification I DAgger [1]: iterative policy training via a reduction to online learning I Coaching (new): update towards easy-to-learn intermediate actions when the oracle is too good to imitate Active Imitation Learning with Noisy Guidance Kianté Brantley University of Maryland kdbrant@cs.umd.edu Amr Sharaf University of Maryland amr@cs.umd.edu Hal Daumé III University of Maryland Microsoft Research me@hal3.name Abstract Imitation learning algorithms provide state-of-the-art results on many structured prediction tasks by learning near-optimal search policies.
A known problem with this ``off-policy" approach is that the robot's errors compound when drifting away from the supervisor's demonstrations. Such …
Sequential pulling policies to flatten and smooth fabrics have applications from surgery to manufacturing to home tasks such as bed making and folding clothes. Imitation Learning for Structured Prediction.
Apr 30, 2019. Imitation Learning with Dataset Aggregation (DAGGER) on Torcs Env. Least expensive form of supervision - don’t need full demonstrations: RL phase can “fill in” missing behavior given partial demonstrations. This work was completed as part my masters thesis requirements, during the late spring through summer of 2018. Imitation Learning with Dataset Aggregation (DAGGER) on Torcs Env. Train a policy using learnt reward function. 2016) also proposed as look-aheads ( Tsuruoka et al. 2016) also proposed as look-aheads ( Tsuruoka et al. Abstract. For this, a set of demonstrations is first collected by an expert (e.g. 09/23/2019 ∙ by Daniel Seita, et al. the imitation learning setting and provide analysis when a supervisor is improving over time.
