Neural Abstract Reasoner

no code implementations12 Nov 2020 Victor Kolev, Bogdan Georgiev, Svetlin Penkov

Abstract reasoning and logic inference are difficult problems for neural networks, yet essential to their applicability in highly structured domains.

Iterative Model-Based Reinforcement Learning Using Simulations in the Differentiable Neural Computer

no code implementations17 Jun 2019 Adeel Mufti, Svetlin Penkov, Subramanian Ramamoorthy

The agent improves its policy in simulations generated by the DNC model and rolls out the policy to the live environment, collecting experiences in new portions or tasks of the environment for further learning.

Learning Programmatically Structured Representations with Perceptor Gradients

no code implementations ICLR 2019 Svetlin Penkov, Subramanian Ramamoorthy

We present the perceptor gradients algorithm -- a novel approach to learning symbolic representations based on the idea of decomposing an agent's policy into i) a perceptor network extracting symbols from raw observation data and ii) a task encoding program which maps the input symbols to output actions.

From explanation to synthesis: Compositional program induction for learning from demonstration

no code implementations27 Feb 2019 Michael Burke, Svetlin Penkov, Subramanian Ramamoorthy

This work introduces an approach to learning hybrid systems from demonstrations, with an emphasis on extracting models that are explicitly verifiable and easily interpreted by robot operators.

Using Program Induction to Interpret Transition System Dynamics

no code implementations26 Jul 2017 Svetlin Penkov, Subramanian Ramamoorthy

Explaining and reasoning about processes which underlie observed black-box phenomena enables the discovery of causal mechanisms, derivation of suitable abstract representations and the formulation of more robust predictions.

Grounding Symbols in Multi-Modal Instructions

no code implementations WS 2017 Yordan Hristov, Svetlin Penkov, Alex Lascarides, Subramanian Ramamoorthy

As robots begin to cohabit with humans in semi-structured environments, the need arises to understand instructions involving rich variability---for instance, learning to ground symbols in the physical world.

Explaining Transition Systems through Program Induction

no code implementations23 May 2017 Svetlin Penkov, Subramanian Ramamoorthy

Explaining and reasoning about processes which underlie observed black-box phenomena enables the discovery of causal mechanisms, derivation of suitable abstract representations and the formulation of more robust predictions.
