Talk Ti

tle: "Probabilistic Inference and Learning for Control"

Talk Abstract:

We propose PILCO, a data-efficient and fully probabilistic model-based

framework for autonomously learning transition dynamics and controllers

nin the absence of expert knowledge. In most autonomous learning
scenario

s either task-specific domain knowledge and/or many trials are
required t

o learn a task. In practical applications, however, full
knowledge abou

t the underlying dynamics or thousands of trials might be
unavailable/imp

ractical. PILCO learns a probabilistic dynamics model
from data only. By

representing and incorporating model uncertainty into
the decision making
process, PILCO reduces model bias and fully
automatically learns to sol

ve fairly complicated control problems in
only a few trials. Across multi

ple complicated control tasks, PILCO
achieves an unprecedented degree of
automation and an unprecedented
speed of learning.
