## Mathemaical Foundations of Informatics Seminar in Veliko Tarnovo

A meeting of the Seminar on Mathematical Foundations of Informatics will be held in Veliko Tarnovo on May 16, 2024, at 4:15 pm, in Room 502 of the Faculty of Mathematics and Informatics, Veliko Tarnovo University. A talk on Lee distance in analyzing and modeling rank data will be delivered by Nikolay I. Ivanov, IMI - BAS. Abstract: Distances on permutations are commonly used in rank data analysis and are an efficient tool for constructing probability models for rankings. In this talk, we consider some probabilistic applications of the Lee distance, which was originally developed as a generalization of the Hamming distance for error correction coding in modulation. In particular, we study the “K-means” clustering procedure based on Lee distance and approximate the normalizing [...]
