Семинар “Математически основи на информатиката” във Велико Търново
На 16 май (четвъртък) от 16:15 часа в зала 502 на ФМИ, ВТУ предстои поредната сбирка на семинара Математически основи на информатиката. Доклад на тема Lee distance in analyzing and modeling rank data ще изнесе Николай И. Николов, главен асистент в секция ИОВС на ИМИ. Резюме: 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 constant needed for assessing the number of clusters. Furthermore, several asymptotic properties of the random [...]
