Direct Advantage Estimation

no code implementations13 Sep 2021 Hsiao-Ru Pan, Nico Gürtler, Alexander Neitz, Bernhard Schölkopf

The predominant approach is to assign credit based on the expected return.

Neural Symbolic Regression that Scales

1 code implementation11 Jun 2021 Luca Biggio, Tommaso Bendinelli, Alexander Neitz, Aurelien Lucchi, Giambattista Parascandolo

We procedurally generate an unbounded set of equations, and simultaneously pre-train a Transformer to predict the symbolic equation from a corresponding set of input-output-pairs.

Divide-and-Conquer Monte Carlo Tree Search

no code implementations1 Jan 2021 Giambattista Parascandolo, Lars Holger Buesing, Josh Merel, Leonard Hasenclever, John Aslanides, Jessica B Hamrick, Nicolas Heess, Alexander Neitz, Theophane Weber

are constrained by an implicit sequential planning assumption: The order in which a plan is constructed is the same in which it is executed.

Learning to interpret trajectories

no code implementations ICLR 2021 Alexander Neitz, Giambattista Parascandolo, Bernhard Schölkopf

By learning to predict trajectories of dynamical systems, model-based methods can make extensive use of all observations from past experience.

CausalWorld: A Robotic Manipulation Benchmark for Causal Structure and Transfer Learning

no code implementations ICLR 2021 Ossama Ahmed, Frederik Träuble, Anirudh Goyal, Alexander Neitz, Yoshua Bengio, Bernhard Schölkopf, Manuel Wüthrich, Stefan Bauer

To facilitate research addressing this problem, we propose CausalWorld, a benchmark for causal structure and transfer learning in a robotic manipulation environment.

Transfer Learning

Learning explanations that are hard to vary

3 code implementations ICLR 2021 Giambattista Parascandolo, Alexander Neitz, Antonio Orvieto, Luigi Gresele, Bernhard Schölkopf

In this paper, we investigate the principle that `good explanations are hard to vary' in the context of deep learning.
