    Abstract:
    Over the past half a century, information theory has evolved from a mathematical tool for analyzing communication systems into an essential framework for studying virtually all aspects of information processing. In the first part of this talk, I\u2019ll present methods to characterize the error exponent of multiple-access channel with feedback and variable-length codes. By making a connection between this problem and distributed hypothesis testing, I will present bounds on the error exponent for such settings. In the second part of the talk, I will discuss the approximation of Boolean functions through the lens of information theory. I will show that this problem is related to distributed processing of correlated random sequences. This problem was studied by Witsenhausen in 1975. With this connection, I will present performance guarantees under the mismatch probability for the approximation of a Boolean function with non-uniform inputs. Applications of this problem is in feature selection in data science and learning of Boolean function.
