Deep Reinforcement Learning for Routing a Heterogeneous Fleet of Vehicles

no code implementations6 Dec 2019 Jose Manuel Vera, Andres G. Abad

Motivated by the promising advances of deep-reinforcement learning (DRL) applied to cooperative multi-agent systems we propose a model and learning procedure to solve the Capacitated Multi-Vehicle Routing Problem (CMVRP) with fixed fleet size.

Learning from multivariate discrete sequential data using a restricted Boltzmann machine model

no code implementations28 Apr 2018 Jefferson Hernandez, Andres G. Abad

A restricted Boltzmann machine (RBM) is a generative neural-network model with many novel applications such as collaborative filtering and acoustic modeling.

Collaborative Filtering using Denoising Auto-Encoders for Market Basket Data

no code implementations14 Aug 2017 Andres G. Abad, Luis I. Reyes-Castro

The contribution of this work is twofold: (1) to identify missing items in observed baskets and, thus, directly providing a CF model; and, (2) to construct a generative model of baskets which may be used, for instance, in simulation analysis or as part of a more complex analytical method.

A Probabilistic Adaptive Search System for Exploring the Face Space

no code implementations28 Apr 2016 Andres G. Abad, Luis I. Reyes Castro

In this paper we propose a novel evolutionary approach for searching the face space that can be used as a facial composite system.

A Dynamic Bayesian Network Model for Inventory Level Estimation in Retail Marketing

no code implementations4 Apr 2016 Luis I. Reyes-Castro, Andres G. Abad

Many retailers today employ inventory management systems based on Re-Order Point Policies, most of which rely on the assumption that all decreases in product inventory levels result from product sales.
