End-to-End Learning for Stochastic Optimization: A Bayesian Perspective
Daniel Kuhn, Yves Rychener, Tobias Sutter
We develop a principled approach to end-to-end learning in stochastic optimization. First, we show that the standard end-to-end learning algorithm admits a Bayesian interpretation and trains a posterior Bayes action map. Building on the insights of this an ...
2023Inferring individual evaluation criteria for reaching trajectories with obstacle avoidance from EEG signals
Aude Billard, José del Rocio Millán Ruiz, Fumiaki Iwane
During reaching actions, the human central nerve system (CNS) generates the trajectories that optimize effort and time. When there is an obstacle in the path, we make sure that our arm passes the obstacle with a sufficient margin. This comfort margin varie ...
Berlin2023Autoantibodies against type I IFNs in humans with alternative NF-κB pathway deficiency
Jacques Fellay, Christian Axel Wandall Thorball, Alessandro Borghesi, Yu Zhang, Peng Zhang, Qian Zhang
Patients with autoimmune polyendocrinopathy syndrome type 1 (APS-1) caused by autosomal recessive AIRE deficiency produce autoantibodies that neutralize type I interferons (IFNs) 1,2 , conferring a predisposition to life-threatening COVID-19 pneumonia 3 . ...
Berlin2023Towards a Framework for Estimation of User Susceptibility to Cybersickness
Cybersickness still poses a significant challenge to the widespread usage of virtual reality (VR), leading to different levels of discomfort and potentially breaking the immersive experience. Researchers have attempted to discover the possible fundamental ...
EPFL2023Impact of Video Processing Operations in Deepfake Detection
The detection of digital face manipulation in video has attracted extensive attention due to the increased risk to public trust. To counteract the malicious usage of such techniques, deep learning-based deepfake detection methods have been developed and ha ...
2023Steps parameters of elderly patients hospitalised for an acute medical illness in a Swiss University Hospital: an observational pilot study
Anisoara Ionescu, Francesco Tommasini
BACKGROUND: Objective mobility goals for elderly hospitalised medical patients remain debated. We therefore studied steps parameters of elderly patients hospitalised for an acute illness, to determine goals for future interventional trials and medical prac ...
SMW supporting association2022Illiquidity and Higher Cumulants
Semyon Malamud, Alberto Mokak Teguia
We characterize the unique equilibrium in an economy populated by strategic CARA investors who trade multiple risky assets with arbitrarily distributed payoffs. We use our explicit solution to study the joint behavior of illiquidity of option contracts. Op ...
OXFORD UNIV PRESS INC2022Uncertainty-aware Flexibility Envelope Prediction in Buildings with Controller-agnostic Battery Models
Colin Neil Jones, Paul Scharnhorst, Rafael Eduardo Carrillo Rangel, Pierre-Jean Alet, Baptiste Schubnel
Buildings are a promising source of flexibility for the application of demand response. In this work, we introduce a novel battery model formulation to capture the state evolution of a single building. Being fully data-driven, the battery model identificat ...
2022Estimating flexibility preferences to resolve temporal scheduling conflicts in activity-based modelling
Michel Bierlaire, Timothy Michael Hillel, Janody Pougala
This paper presents a novel activity-based demand model that combines an optimisation framework for continuous temporal scheduling decisions (i.e. activity timings and durations) with traditional discrete choice models for non-temporal choice dimensions (i ...
SPRINGER2022Patron-Driven Acquisition et Evidence-Based Acquisition: Comment implémenter ces modèles afin d’étendre l’offre documentaire dans une bibliothèque ?
Nowadays, usage-based acquisition models for e-books, as PDA and EBA, are quite spread and allow libraries to offer wider collections, without acquiring them. A PDA with Ebook Central was implemented in 2019 and a first EBA with Wiley in 2021. The EPFL Lib ...
