## In Memoriam: Eugene Spiegel

We are saddened to report that our former colleague Eugene Spiegel passed away earlier this week. Gene obtained his PhD from MIT in 1965. After a post-doc at Caltech he joined UConn in September 1967 as an Assistant Professor. Gene supervised six doctoral dissertations at UConn and, along with some other colleagues, built up the […]

[Read More]## UConn Hosting MathCounts Competition

On Saturday, February 9, the Department of Mathematics will host the Eastern Chapter of the MathCounts competition. For many years this competition took place at the Coast Guard Academy, but the recent government shutdown made it impossible. UConn came to rescue and hope to host up to 230 mathletes this week. One of the teams […]

With the advantage of hindsight, I will also show how this result has influenced many modern ideas in graph theory and graph drawing. Despite covering a lot of ground, the talk should be widely accessible.

"Computational Cognitive Modeling for Syntax and Semantics"

Adrian Brasoveanu (joint work with Jakub Dotlacil)

Abstract: I introduce a typical experimental task in psycholinguistics -- self-paced reading -- and show how to build end-to-end simulations of a human participant in such an experiment; end-to-end means that we model visual and motor processes together with specifically linguistic processes (syntactic and semantic parsing) in a complete model of the experimental task. The model embeds theoretical hypotheses about linguistic representations and parsing processes in an independently motivated cognitive architecture (ACT-R). In turn, the resulting cognitive models can be embedded in Bayesian models to fit them to experimental data, estimate their parameters and perform quantitative model comparison for qualitative theories.

All welcome!

Abstract: During World War II the German army used tanks to devastating advantage. The Allies needed accurate estimates of their tank production and deployment. They used two approaches to find these values: spies, and statistics. In this talk we describe the statistical approach and its generalization. Assuming the tanks are labeled consecutively starting at 1, if we observe $k$ serial numbers from an unknown number $N$ of tanks, with the maximum observed value $m$, what is the best estimate for $N$? This is now known as the German Tank Problem, and is a terrific example of the applicability of mathematics and statistics in the real world. We quickly review some needed combinatorial identities (which is why we are able to obtain clean, closed form expressions), give the proof for the standard problem, discuss the generalization, and show how if we were unable to do the algebra we could guess the formula by an application of linear regression, thus highlighting its power and applicability. Most of the talk only uses basic algebra and elementary knowledge of WWII.
