Continuous-time Value Function Approximation in Reproducing Kernel Hilbert Spaces

no code implementations NeurIPS 2018 Motoya Ohnishi, Masahiro Yukawa, Mikael Johansson, Masashi Sugiyama

Motivated by the success of reinforcement learning (RL) for discrete-time tasks such as AlphaGo and Atari games, there has been a recent surge of interest in using RL for continuous-time control of physical systems (cf.

A stochastic behavior analysis of stochastic restricted-gradient descent algorithm in reproducing kernel Hilbert spaces

no code implementations14 Oct 2014 Masa-aki Takizawa, Masahiro Yukawa, Cedric Richard

This paper presents a stochastic behavior analysis of a kernel-based stochastic restricted-gradient descent method.

Adaptive Learning in Cartesian Product of Reproducing Kernel Hilbert Spaces

no code implementations5 Aug 2014 Masahiro Yukawa

We propose a novel adaptive learning algorithm based on iterative orthogonal projections in the Cartesian product of multiple reproducing kernel Hilbert spaces (RKHSs).

Kernel-Based Adaptive Online Reconstruction of Coverage Maps With Side Information

no code implementations3 Apr 2014 Martin Kasparick, Renato L. G. Cavalcante, Stefan Valentin, Slawomir Stanczak, Masahiro Yukawa

In this paper, we address the problem of reconstructing coverage maps from path-loss measurements in cellular networks.
