Constrained Exploration and Recovery from Experience Shaping

1 code implementation21 Sep 2018 Tu-Hoa Pham, Giovanni De Magistris, Don Joven Agravante, Subhajit Chaudhury, Asim Munawar, Ryuki Tachibana

We consider the problem of reinforcement learning under safety requirements, in which an agent is trained to complete a given task, typically formalized as the maximization of a reward signal over time, while concurrently avoiding undesirable actions or states, associated to lower rewards, or penalties.

Reinforcement Learning Testbed for Power-Consumption Optimization

1 code implementation21 Aug 2018 Takao Moriyama, Giovanni De Magistris, Michiaki Tatsubori, Tu-Hoa Pham, Asim Munawar, Ryuki Tachibana

Common approaches to control a data-center cooling system rely on approximated system/environment models that are built upon the knowledge of mechanical cooling and electrical and thermal management.

OptLayer - Practical Constrained Optimization for Deep Reinforcement Learning in the Real World

no code implementations22 Sep 2017 Tu-Hoa Pham, Giovanni De Magistris, Ryuki Tachibana

While deep reinforcement learning techniques have recently produced considerable achievements on many decision-making problems, their use in robotics has largely been limited to simulated worlds or restricted motions, since unconstrained trial-and-error interactions in the real world can have undesirable consequences for the robot or its environment.

Towards Force Sensing From Vision: Observing Hand-Object Interactions to Infer Manipulation Forces

no code implementations CVPR 2015 Tu-Hoa Pham, Abderrahmane Kheddar, Ammar Qammaz, Antonis A. Argyros

We present a novel, non-intrusive approach for estimating contact forces during hand-object interactions relying solely on visual input provided by a single RGB-D camera.
