Further results on latent discourse models and word embeddings
We discuss some properties of generative models for word embeddings. Namely, (Arora et al., 2016) proposed a latent discourse model implying the concentration of the partition function of the word vectors. This concentration phenomenon led to an asymptotic ...
MICROTOME PUBL2021Collaborative Learning in the Jungle (Decentralized, Byzantine, Heterogeneous, Asynchronous and Nonconvex Learning)
Rachid Guerraoui, Sadegh Farhadkhani, El Mahdi El Mhamdi, Le Nguyen Hoang, Sébastien Louis Alexandre Rouault, Arsany Hany Abdelmessih Guirguis
We study Byzantine collaborative learning, where n nodes seek to collectively learn from each others' local data. The data distribution may vary from one node to another. No node is trusted, and f < n nodes can behave arbitrarily. We prove that collaborati ...
2021Bootstrapping Heisenberg magnets and their cubic instability
We study the critical O(3) model using the numerical conformal bootstrap. In particular, we use a recently developed cutting-surface algorithm to efficiently map out the allowed space of conformal field theory data from correlators involving the leading O( ...
AMER PHYSICAL SOC2021Virtual metrology as an approach for product quality estimation in Industry 4.0: a systematic review and integrative conceptual framework
Virtual metrology (VM) involves estimating a product's quality directly from production process data without physically measuring it. This enables the product quality of each unit of production to be monitored in real time, while preserving the process eff ...
TAYLOR & FRANCIS LTD2021Yapa: Accelerated Proximal Algorithm For Convex Composite Problems
Mireille El Gheche, Giovanni Chierchia
Proximal splitting methods are standard tools for nonsmooth optimization. While primal-dual methods have become very popular in the last decade for their flexibility, primal methods may still be preferred for two reasons: acceleration schemes are more effe ...
IEEE2021Cyber-Physical LPG Debutanizer Distillation Columns: Machine-Learning-Based Soft Sensors for Product Quality Monitoring
Refineries execute a series of interlinked processes, where the product of one unit serves as the input to another process. Potential failures within these processes affect the quality of the end products, operational efficiency, and revenue of the entire ...
2021What about the ethics of applying artificial intelligence to bodies?
Images convey, through representations of bodies, in the press, cinema and art, one or more gender imaginaries while acting as vectors in the process of globalization. The recurrence or similarity of some of these images reveals the diffusion or persistenc ...
2021Laser-induced liquid micro-jets for drug delivery
Jet injection devices have been studied and developed for transdermal drug delivery to avoid the use of needles. Such contact-less devices provide several advantages such as better dose control, lateral and depth localisation, lower collateral damage than ...
EPFL2021Unconventional time-bandwidth performance of resonant cavities with nonreciprocal coupling
Camille Sophie Brès, Davide Grassani, Ivan Cardea, Kosmas Tsakmakidis
The time-bandwidth limit is a mathematical tenet that affects all reciprocal resonators, stating that the product of the spectral bandwidth that can couple into a resonant system and its characteristic energy decay time is always equal to 1. Here, we devel ...
2021On complete reducibility of tensor products of simple modules over simple algebraic groups
Let G be a simply connected simple algebraic group over an al- gebraically closed field k of characteristic p > 0. The category of rationalG-modules is not semisimple. We consider the question of when the tensorproduct of two simple G-modules L(λ) and L(μ) ...
