Dr. Daniel Smith-Tone (National Institute of Standards and Technology). Currently, the National Institute of Standards and Technology (NIST) and the international cryptography research community are engaged in a massive effort to optimize and evaluate candidate post-quantum public key algorithms; i.e. cryptosystems we can use to secure our public key infrastructure against adversaries with access to quantum computers.  One family of candidate algorithms is based on the classical problem of solving systems of multivariate nonlinear equations, a problem at the root…

Proximity Curves for Potential-Based Clustering

June 23, 2021 @ 10:00 am - 10:45 am
Online at

Speaker: Prof. Daniel Neagu, University of Bradford, UK Venue: The talk will be delivered online at: Title: Proximity Curves for Potential-Based Clustering Abstract: The talk introduces the concept of proximity curve and a new clustering algorithm for a finite set of data points. Each point is endowed with a potential constructed by means of a multi-dimensional Cauchy density, contributing to an overall anisotropic potential function. Guided by the steepest descent algorithm, the data points are successively visited and removed…
