Logic seminar: Achilles Beros
Sep 1 @ 1:30 pm – Sep 1 @ 2:20 pm

Achilles Beros will
speak on “Algorithmic learning and the arithmetic hierarchy”

Summary:

I will present a theorem from my thesis that establishes the arithmetic
complexity of a well-known learning criterion. Two other papers have
been published since then that continue the line of research. I will
discuss the newer papers as well as broader connections between
recursion theory and learning theory.

Logic seminar: Mushfeq Khan @ Keller Hall 303
Sep 8 @ 1:30 pm – Sep 8 @ 2:30 pm

This week the Sporadic Logic Seminar will be Mushfeq Khan speaking on
“Turing degrees and Muchnik degrees of recursively
bounded DNR functions”.

Summary:

This talk is based on a forthcoming paper by Steve Simpson. It contains
some results that shed light on a part of the Muchnik lattice that remains
poorly understood: the various degrees of recursively bounded DNR functions
obtained by varying the recursive bound.

Title: On the Radon Transform

Abstract: In this talk we will introduce, motivate and discuss some of the elementary properties of the Radon transform operator. We will cover a little about how to invert this operator via its adjoint (i.e. back-projection operator) and approximate identities.
