Optimizing Dynamic Aperture Studies with Active Learning
Davide Di Croce, Tatiana Pieloni, Ekaterina Krymova, Massimo Giovannozzi
Dynamic aperture is an important concept for the study of non-linear beam dynamics in circular accelerators. It describes the extent of the phase-space region where a particle's motion remains bounded over a given number of turns. Understanding the feature ...
2024Textual Explanations and Critiques in Recommendation Systems
Artificial intelligence and machine learning algorithms have become ubiquitous. Although they offer a wide range of benefits, their adoption in decision-critical fields is limited by their lack of interpretability, particularly with textual data. Moreover, ...
EPFL2022On Succinct Non-interactive Arguments in Relativized Worlds
Succinct non-interactive arguments of knowledge (SNARKs) are cryptographic proofs with strong efficiency properties. Applications of SNARKs often involve proving computations that include the SNARK verifier, a technique called recursive composition. Unfort ...
SPRINGER INTERNATIONAL PUBLISHING AG2022Magnetization-prepared 2 Rapid Gradient-Echo MRI for B-1 Insensitive 3D T1 Mapping of Hip Cartilage: An Experimental and Clinical Validation
Background: Often used for T1 mapping of hip cartilage, three-dimensional (3D) dual-flip-angle (DFA) techniques are highly sensitive to flip angle variations related to B-1 inhomogeneities. The authors hypothesized that 3D magnetization-prepared 2 rapid gr ...
RADIOLOGICAL SOC NORTH AMERICA2021Genetic-optimised aperiodic code for distributed optical fibre sensors
Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Simon Adrien Zaslawski, Sheng Wang, Jian Wu
Distributed optical fibre sensors deliver a map of a physical quantity along an optical fibre, providing a unique solution for health monitoring of targeted structures. Considerable developments over recent years have pushed conventional distributed sensor ...
2020Penalization and Bayesian numerical methods for multiscale inverse problems
In this thesis we consider inverse problems involving multiscale elliptic partial differential equations. The name multiscale indicates that these models are characterized by the presence of parameters which vary on different spatial scales (macroscopic, m ...
EPFL2019Placement of Virtual Containers on NUMA systems: A Practical and Comprehensive Model
Baptiste Joseph Eustache Lepers
Our work addresses the problem of placement of threads, or virtual cores, onto physical cores in a multicore NUMA system. Different placements result in varying degrees of contention for shared resources, so choosing the right placement can have a large ef ...

USENIX ASSOC2018When Stuck, Flip a Coin
Many modern services need to routinely perform tasks on a large scale. This prompts us to consider the following question:
How can we design efficient algorithms for large-scale computation?
In this thesis, we focus on devising a general strategy to addr ...
