Coloquio del viernes 18/10: Learning to navigate in dynamic environments

El coloquio del viernes 18 de octubre se titula "Learning to navigate in dynamic environments". El expositor es Antonio Celani del The Abdus Salam International Center for Theoretical Physics - ICTP, Trieste, Italy. Se realizará a las  14.30 hs. en el Salón de Actos del Instituto Balseiro, en el Centro Atómico Bariloche (Av. Bustillo 9500). La entrada es gratuita y abierta a todo el público. Para ingresar, es necesario presentar el DNI en la entrada del CAB 

Resumen:

Some animals can complete very difficult navigation tasks in a seemingly effortless way: homing pigeons can fly back home from unfamiliar places that are hundreds of kilometers away from their loft; male moths can reach females from distances of several hundreds of meters; migratory birds can cross the oceans with minimal energy expenditure by relying on ascending air currents. The fundamental aspect that is common to all these behaviors is the highly dynamic and unpredictable nature of the environment -- the turbulent atmospheric conditions. In this talk I will focus on the example of soaring birds who exploit thermal convection to reach great heights without flapping their wings. How soaring birds find and navigate thermals within the complex landscape of a turbulent convective atmosphere is unknown. Reinforcement learning, a branch of machine intelligence, provides an appropriate framework to identify an effective navigational strategy as a sequence of decisions taken in response to environmental cues. I will discuss how to use it to suggest possible strategies used by birds and also to train autonomous gliders to navigate atmospheric thermals.

Minibio:

Antonio Celani earned his PhD at the Politecnico di Torino, Italy in 1998. After post-doctoral fellowships at Max Planck Institute in Munich and at the Observatoire de la Cote d'Azur he became researcher for the French National Research Council (CNRS) in 2000. In 2007 he joined the Institut Pasteur Paris as a research director where he started working at the interface between physics and biology. Since 2014 he is also research scientist at The Abdus Salam International Center for Theoretical Physics - ICTP where he works on subjects at the interface between physics, biology, and artificial intelligence.
