Working Backwards: Learning to Place by Picking

no code implementations4 Dec 2023 Oliver Limoyo, Abhisek Konar, Trevor Ablett, Jonathan Kelly, Francois R. Hogan, Gregory Dudek

By doing so, the policy can generalize to object placement scenarios outside of the training environment without privileged information (e. g., placing a plate picked up from a table).

Multimodal and Force-Matched Imitation Learning with a See-Through Visuotactile Sensor

no code implementations2 Nov 2023 Trevor Ablett, Oliver Limoyo, Adam Sigal, Affan Jilani, Jonathan Kelly, Kaleem Siddiqi, Francois Hogan, Gregory Dudek

An STS sensor can be switched between visual and tactile modes by leveraging a semi-transparent surface and controllable lighting, allowing for both pre-contact visual sensing and during-contact tactile sensing with a single sensor.

Learning from Guided Play: Improving Exploration for Adversarial Imitation Learning with Simple Auxiliary Tasks

1 code implementation30 Dec 2022 Trevor Ablett, Bryan Chan, Jonathan Kelly

In this work, we show that the standard, naive approach to exploration can manifest as a suboptimal local maximum if a policy learned with AIL sufficiently matches the expert distribution without fully learning the desired task.

Learning Sequential Latent Variable Models from Multimodal Time Series Data

1 code implementation21 Apr 2022 Oliver Limoyo, Trevor Ablett, Jonathan Kelly

In this work, we present a self-supervised generative modelling framework to jointly learn a probabilistic latent state representation of multimodal data and the respective dynamics.

Learning from Guided Play: A Scheduled Hierarchical Approach for Improving Exploration in Adversarial Imitation Learning

1 code implementation16 Dec 2021 Trevor Ablett, Bryan Chan, Jonathan Kelly

We present Learning from Guided Play (LfGP), a framework in which we leverage expert demonstrations of, in addition to a main task, multiple auxiliary tasks.

Seeing All the Angles: Learning Multiview Manipulation Policies for Contact-Rich Tasks from Demonstrations

1 code implementation28 Apr 2021 Trevor Ablett, Yifan Zhai, Jonathan Kelly

In this work, we demonstrate that a multiview policy can be found through imitation learning by collecting data from a variety of viewpoints.
