You are warmly invited to attend a talk by Francesca Panero. Details below. Title: Sparse spatial random graphs Where: USI Lugano East Campus, room D5.01, and online When: 9 June, 12:30pm Abstract: We present a statistical model to describe spatial random graphs through the graphex process, a construction which exploits the Bayesian nonparametric framework in order to achieve flexibility and interpretability when conducting inference. We provide a number of asymptotic results, namely that the model is able to describe both sparse and dense networks, is equipped with positive global and local clustering coefficients and can achieve both single or double power law degree distributions whose exponents are easily tuned. We present a way to perform posterior inference through MCMC algorithms. Finally, we place our proposal into the more general literature of spatial random graphs, discussing the relations with hyperbolic random graphs, scale-free percolation and sparse latent space models. The speaker: Francesca Panero is a visiting researcher at IDSIA and a DPhil candidate in Statistics at the University of Oxford. She is working with Prof. François Caron and Prof. Judith Rousseau on random graphs, exploring both asymptotic properties of models based on graphex processes and new modelling approaches to describe spatial networks. Prior to this, she obtained a BSc and a MSc in Mathematics at the University of Turin and Collegio Carlo Alberto. -- Marco Scutari Senior Researcher in Bayesian Networks and Graphical Models Istituto Dalle Molle di Studi sull'Intelligenza Artificiale (IDSIA) http://www.bnlearn.com/about

[Lumi] Talk on "How values encroach on understanding from opaque machine learning models" by Emily Sullivan (Eindhoven University of Technology) [Thursday, June 10, 2021, at 17:00 (5pm) CET, on Zoom]

by IDSIA Announcements of talks＠IDSIA

We are happy to announce the fourth talk of the series of webinars at IDSIA dedicated to the foundational, epistemological and ethical aspects of AI. ******* *Title: How values encroach on understanding from opaque machine learning models *Abstract: How much is model opacity a problem for explanation and understanding from machine learning models? I argue that there are several ways in which non-epistemic values influence the extent to which model opacity undermines explanation and understanding. I consider three stages of the scientific process surrounding ML models where the influence of non-epistemic values emerges: 1) establishing the empirical link between the model and phenomenon, 2) explanation, and 3) attributions of understanding. *Speaker: Emily Sullivan, Assistant Professor of Philosophy & Ethics, Department of Industrial Engineering & Innovation Sciences, Eindhoven University of Technology (personal webpage: http://www.eesullivan.com) *Date: Thursday, June 10, 2021, at 17:00 (5pm) CET, on Zoom. *Zoom Link: https://supsi.zoom.us/j/62374021896?pwd=WWNIKy9MVm9DNThHeHBpazdBS1YzQT09 ID meeting: 623 7402 1896 Passcode: emily
