[Talk] Felipe Garrido-Lucero – Who: Felipe Garrido-Lucero When: Wednesday 10/01, 14:00-15:00 Where: Room 106 and zoom (https://univ-grenoble-alpes-fr.zoom.us/my/mertikop) What: Fairness Challenges in AI: Insights into Data-set Valuation and Matching Markets More: Fairness is an increasingly research subject within various computer science sub-disciplines such as machine learning and market design. In this presentation we will discuss two possible fairness challenges: the data-set valuation problem and the price of fairness in bipartite matching markets. The data-set valuation problem addresses measuring the contributions of agents when collaborating on machine learning tasks. By employing tools from both machine learning and game theory, we model this as a cooperative game and present an approach to approximate the Shapley value of players. The method demonstrates superior performance compared to Monte-Carlo state-of-the-art techniques, supported by theoretical guarantees. The price of fairness (PoF) quantifies the optimality loss when applying fairness constraints to a problem. Examining the egalitarian PoF in bipartite matching markets, where agents belong to distinct groups, we exploit matroid and geometric tools to characterize fair matchings, optimal matchings, and their intersection. An adversarial analysis reveals that a PoF of 1 is always achievable for two groups, while for a greater number of groups, the PoF can be arbitrarily large. Bâtiment IMAG (106) |

[Talk] Henri Lefebvre – Who: Henri Lefebvre When: Friday 19/01, 10:30-11:30 Where: Room 406 What: Exact Methods in Adjustable Robust Optimization More: This talk will be dedicated to solving complex decision-making problems in which (part of) the input data is not known at decision time. More precisely, we will discuss problems in which a two-stage decision phase is at stake. In the first stage, decisions must be made without complete information about the input parameters, while in the second stage, additional decisions can be informed by revealed information regarding the parameters. More specifically, we will dive into the theoretical derivation and practical use of exact methods for such problems with particular emphasis on the challenging setting in which the second-stage decisions are solution of a mixed-integer non-linear problem.

Martin Quinson. SmolPhone: a smartphone with energy limits – This talk explores the smartphone design space to achieve energy sobriety. At its core, the proposed platform has a compute-limited but energy efficient microcontroller (MCU). Another processor can be attached to execute legacy Linux applications. Some tasks are offloaded to the Wi-Fi network controller. Our design prefers an energy-efficient variant of the 4G cellular network, which is turned off as often as possible. We are in the process of designing a hardware evaluation board to implement the vision presented in this talk.
