An improved tabular data generator with VAE-GMM integration

no code implementations12 Apr 2024 Patricia A. Apellániz, Juan Parras, Santiago Zazo

Furthermore, our model offers enhanced flexibility by allowing the use of various differentiable distributions for individual features, making it possible to handle both continuous and discrete data types.

SAVAE: Leveraging the variational Bayes autoencoder for survival analysis

1 code implementation22 Dec 2023 Patricia A. Apellániz, Juan Parras, Santiago Zazo

As in many fields of medical research, survival analysis has witnessed a growing interest in the application of deep learning techniques to model complex, high-dimensional, heterogeneous, incomplete, and censored medical data.

Learning Parametric Closed-Loop Policies for Markov Potential Games

no code implementations ICLR 2018 Sergio Valcarcel Macua, Javier Zazo, Santiago Zazo

This is a considerable improvement over the previously standard approach for the CL analysis of MPGs, which gives no approximate solution if no NE belongs to the chosen parametric family, and which is practical only for simple parametric forms.

Diff-DAC: Distributed Actor-Critic for Average Multitask Deep Reinforcement Learning

no code implementations28 Oct 2017 Sergio Valcarcel Macua, Aleksi Tukiainen, Daniel García-Ocaña Hernández, David Baldazo, Enrique Munoz de Cote, Santiago Zazo

We propose a fully distributed actor-critic algorithm approximated by deep neural networks, named \textit{Diff-DAC}, with application to single-task and to average multitask reinforcement learning (MRL).

Distributed Policy Evaluation Under Multiple Behavior Strategies

no code implementations30 Dec 2013 Sergio Valcarcel Macua, Jianshu Chen, Santiago Zazo, Ali H. Sayed

We apply diffusion strategies to develop a fully-distributed cooperative reinforcement learning algorithm in which agents in a network communicate only with their immediate neighbors to improve predictions about their environment.
