Hierarchical Representation Learning for Markov Decision Processes

no code implementations3 Jun 2021 Lorenzo Steccanella, Simone Totaro, Anders Jonsson

In this paper we present a novel method for learning hierarchical representations of Markov decision processes.

Hierarchical reinforcement learning for efficient exploration and transfer

no code implementations12 Nov 2020 Lorenzo Steccanella, Simone Totaro, Damien Allonsius, Anders Jonsson

Sparse-reward domains are challenging for reinforcement learning algorithms since significant exploration is needed before encountering reward for the first time.

Adaptive Smoothing Path Integral Control

no code implementations13 May 2020 Dominik Thalmeier, Hilbert J. Kappen, Simone Totaro, Vicenç Gómez

We identify PICE as the infinite smoothing limit of such technique and show that the sample efficiency problems that PICE suffers disappear for finite levels of smoothing.

Kafnets: kernel-based non-parametric activation functions for neural networks

2 code implementations13 Jul 2017 Simone Scardapane, Steven Van Vaerenbergh, Simone Totaro, Aurelio Uncini

Neural networks are generally built by interleaving (adaptable) linear layers with (fixed) nonlinear activation functions.
