About

Overview

My main interest lies in Artificial General Intelligence and Robotics, and in particular the emergence of common-sense knowledge through sensorimotor prediction. Sensorimotor prediction is a very powerful drive, allowing an embodied agent to acquire knowledge and build a model about its world. I am particularly interested in end-to-end self-supervised learning approaches inspired from insights in Neuroscience and Cognitive Development. Recently, I have been working on topics involving agents navigating in a physical world and learning representations of spatial displacement, as well as learning the structure of their environment (emergence of object representation), guided solely by prediction on continuous sensorimotor streams.

List of topics of Interest:
- Artificial General Intelligence
- State Representation Learning
- Sensorimotor Prediction
- Continual Learning
