Bridging the Gap Between Target Networks and Functional Regularization

no code implementations21 Oct 2022 Alexandre Piche, Valentin Thomas, Joseph Marino, Rafael Pardinas, Gian Maria Marconi, Christopher Pal, Mohammad Emtiyaz Khan

However, learning the value function via bootstrapping often leads to unstable training due to fast-changing target values.

Implicit Offline Reinforcement Learning via Supervised Learning

no code implementations21 Oct 2022 Alexandre Piche, Rafael Pardinas, David Vazquez, Igor Mordatch, Chris Pal

Despite the benefits of using implicit models to learn robotic skills via BC, offline RL via Supervised Learning algorithms have been limited to explicit models.

Bridging the Gap Between Target Networks and Functional Regularization

1 code implementation4 Jun 2021 Alexandre Piché, Valentin Thomas, Rafael Pardinas, Joseph Marino, Gian Maria Marconi, Christopher Pal, Mohammad Emtiyaz Khan

Our findings emphasize that Functional Regularization can be used as a drop-in replacement for Target Networks and result in performance improvement.

LOOC: Localize Overlapping Objects with Count Supervision

1 code implementation3 Jul 2020 Issam H. Laradji, Rafael Pardinas, Pau Rodriguez, David Vazquez

For localization, LOOC achieves a strong new baseline in the novel problem setup where only count supervision is available.

Objects of violence: synthetic data for practical ML in human rights investigations

no code implementations1 Apr 2020 Lachlan Kermode, Jan Freyberg, Alican Akturk, Robert Trafford, Denis Kochetkov, Rafael Pardinas, Eyal Weizman, Julien Cornebise

We introduce a machine learning workflow to search for, identify, and meaningfully triage videos and images of munitions, weapons, and military equipment, even when limited training data exists for the object of interest.
