Convex Quantization Preserves Logconcavity
A logconcave likelihood is as important to proper statistical inference as a convex cost function is important to variational optimization. Quantization is often disregarded when writing likelihood models, ignoring the limitations of the physical detectors ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Semiclassical methods in conformal field theories scrutinized by the epsilon-expansion
Conformal Field Theories (CFTs) are crucial for our understanding of Quantum Field Theory (QFT). Because of their powerful symmetry properties, they play the role of signposts in the space of QFTs. Any method that gives us information about their structure ...
EPFL2022Finite-Level Quantization Procedures for Construction and Decoding of Polar Codes
We consider finite-level, symmetric quantization procedures for construction and decoding of polar codes. Whether polarization occurs in the presence of quantization is not known in general. Hassani and Urbanke have shown that a simple three-level quantiza ...
2020Quantization Design for Distributed Optimization
Colin Neil Jones, Ye Pu, Melanie Nicole Zeilinger
We consider the problem of solving a distributed optimization problem using a distributed computing platform, where the communication in the network is limited: each node can only communicate with its neighbors and the channel has a limited data-rate. A co ...

Riccardo Rattazzi, Alexander Monin, David Pirtskhalava, Fiona Katharina Seibold
Hellerman et al. (arXiv:1505.01537) have shown that in a generic CFT the spectrum of operators carrying a large U(1) charge can be analyzed semiclassically in an expansion in inverse powers of the charge. The key is the operator state correspondence by whi ...
Springer2017Noether Theorems and Quantum Anomalies
A quantum anomaly is the breaking of symmetry with respect to some transformations after the quantization of a classical Hamiltonian or Lagrangian system. It is shown that both the Noether theorems (including their infinite-dimensional versions) and the ex ...
Springer Verlag2017Graph Signal Processing
Over the past few decades we have been experiencing an explosion of information generated by large networks of sensors and other data sources. Much of this data is intrinsically structured, such as traffic evolution in a transportation network, temperature ...
EPFL2016From the free surface flow of a viscoelastic fluid towards the elastic deformation of a solid
The free surface flow of an Oldroyd-B viscoelastic fluid is considered, following A. Bonito, M. Picasso, and M. Laso (2006)[1]. When removing a term in the extra-stress constitutive relation, the description of an elastic incompressible solid is obtained, ...
