DEVELOPMENTAL ROBOTICS AND

CURIOSITY- DRIVEN LEARNING

 

NEWS: More up to date information is now available on my FLOWERS INRIA team web site.

Can a robot be curious? How can a robot learn new tricks by itself and continuously during its lifetime? What mechanisms explain open-ended cognitive development? How can children development inspire robot builders, and how robotic models can be useful to developmental psychology? These are the central questions that I study in developmental robotics.

Studying development, in children or in cognitive robots, is intrinsically difficult because of the complex interplay between embodiment, learning mechanisms and environmental dynamics. A relevant integrative approach can be pursued by viewing development as a complex system the dynamics of which can be studied with embodied models. In particular, I conduct research on intrinsic motivation systems (also called intrinsic value systems or systems with artificial curiosity), that can drive a robot to continuously try to master new know-how. The aim is to construct machines implementing such general capacities as artificial curiosity.

This approach might not only help us understand the mechanisms underlying human development, but it might also provide radically new techniques for building intelligent robots. Indeed, as opposed to the work in classical artificial intelligence in which engineers impose pre-defined anthropocentric tasks to robots, the techniques we develop endow the robots with the capacity of deciding by themselves which are the activities that are maximally fitted to their current capabilities. Our developmental robots autonomously and actively choose their learning situations, thus beginning by simple ones and progressively increasing their complexity. No tasks are pre-specified to the robots, which are only provided with an internal abstract reward function. For example, in the case of the Intelligent Adaptive Curiosity which I developed with my former Sony CSL colleague Frédéric Kaplan, this internal reward function pushes the robot to sear
ch for situations where its learning progress is maximal.

In particular, we have built an experimental setup, called the Playground Experiment, which allowed to show how the curiosity algorithm which we developped allows for the self-organization of developmental trajectories with sequences of behavioural stages of increasing complexity.
