Achilles Beros will
speak on “Algorithmic learning and the arithmetic hierarchy”
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.
Keller Hall 303
This week the Sporadic Logic Seminar will be Mushfeq Khan speaking on
“Turing degrees and Muchnik degrees of recursively
bounded DNR functions”.
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.
I will give a tutorial talk, how to use LEAN and Coq/MathCopm.SSReflect, which are famous proof assistant systems.
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.
