Research Topics (Last update: November 2024)

  • Multi-agent reinforcement learning. Application to pedestrians simulation.
    Keywords: Reinforcement Learning, pedestrians simulation. Emergent collective behaviors. My  Doctoral Thesis applied Multi-Agent reinforcement learning to simulate pedestrians trajectories in 3D graphics environments. We have also developed a consultoring task about this subject with the company Toolchef in  UK.
  • Multi-agent reinforcement learning applied to games.  Recently, we have assessing the use of  state-of-the-art Multi-agent reinforcement learning algorithms such as PPO, VDN and QMIX for learning behaviors in social networks-oriented role playing games. We have developed behaviors that surpass human skills in a multiplayer online roleplaying game settled on  Discord. Paper being reviewed.
  • Multi-agent simulation framework based on evolutionary techniques for the analysis of the Electrical Vehicle (EV) market share. In colaboration with the University Carlos III of Madrid I have participated in a project founded by REPSOL S.A. company. The developed simulator uses Genetic Algorithms to optimize the configurations and placement of electric charging stations for EVs. Paper being reviewed.
  • Hybrid techniques for behavior learning in 3D graphics characters. We are studying the application of state-of-the-art Quality Diversity (QD) techniques (Map-Elites) with deep learning and deep reinforcement learning to get diverse high quality behaviors in 3D graphics standard locomotion problems (HalfCheetah, Ant, Humanoid).
  • Machine Learning techniques for the ADN analysis in biological remains to identify dog owners. Dog droppings on public roads is a sanitary problem in many cities. Using samples of these biological remains, we can obtain the ADN signature of the dog. I participate in a project for improving the detection accuracy of these ADN tests to identify  dog owners who did not comply with current legislation to pick up their dogs' excrement from public roads. 
  • Deep learning to locate different flow pressure areas in the aorta inner walls in human heart. I participate in a study for predicting blood preassure in the inner walls of aorta based on  specific topological and geometrical information. We use deep convolutional networks to learn to predict flow and pressure in internal walls of aorta using images coding geometrical and topological characteristics.
