- Course Description
This course aims to
understand the principles and mechanisms of cognitive agents that learn
continuously and sequentially over lifetime in dynamic environments. In this
lifelong learning setting, the target distribution of the learning is
typically non-stationary and changing. This is in sharp contrast to
the usual assumptions made in most supervised and unsupervised learning
algorithms. That is, lifelong sequential learning violates the assumption of
the examples being i.i.d (independent and
identically distributed) and the assumption of availability of all the
training data at the outset of learning. However, lifelong learning research
is still in its infancy and there is no single universal algorithm that
addresses all these issues. Thus, in this course we discuss three specific
aspects of lifelong learning problems, i.e. sequence learning, sequential
decision making, and moving target tracking. We review the existing machine
learning algorithms that best deal with these problems so far, namely hidden
Markov models, reinforcement learning, and particle filters. Based on this
knowledge, we will discuss how to develop a humanlike intelligent agent that
that can learn actively, sequentially, and lifelong in real-time from
real-life sensing data in real-worlds.
