Data Field Theory: Theory and Applications of the Functional Renormalization Group for Signal Detection
Riccardo Finotello, Vincent Lahoche, Dine Ousmane Samary +1
We review the renormalization group framework for signal detection in high-dimensional data, tailored to the regime where the signal may be of extensive rank and does not separate…
Field Theory of Data: Anomaly Detection via the Functional Renormalization Group. The 2D Ising Model as a Benchmark
Riccardo Finotello, Vincent Lahoche, Parham Radpay +1
We establish a correspondence between anomaly detection in high-noise regimes and the renormalization group flow of non-equilibrium field theories. We provide a physical grounding…
Learning Complex Physical Regimes via Coverage-oriented Uncertainty Quantification: An application to the Critical Heat Flux
Michele Cazzola, Alberto Ghione, Lucia Sargentini +2
A central challenge in scientific machine learning (ML) is the correct representation of physical systems governed by multi-regime behaviours. In these scenarios, standard data ana…
Functional Renormalization for Signal Detection: Dimensional Analysis and Dimensional Phase Transition for Nearly Continuous Spectra Effective Field Theory
Riccardo Finotello, Vincent Lahoche, Dine Ousmane Samary
Signal detection in high dimensions is a critical challenge in data science. While standard methods based on random matrix theory provide sharp detection thresholds for finite-rank…
Deep learning complete intersection Calabi-Yau manifolds
Harold Erbin, Riccardo Finotello
We review advancements in deep learning techniques for complete intersection Calabi-Yau (CICY) 3- and 4-folds, with the aim of understanding better how to handle algebraic topologi…
Functional renormalization group for signal detection and stochastic ergodicity breaking
Harold Erbin, Riccardo Finotello, Bio Wahabou Kpera +2
Signal detection is one of the main challenges of data science. As it often happens in data analysis, the signal in the data may be corrupted by noise. There is a wide range of tec…
Trustworthiness of Laser-Induced Breakdown Spectroscopy Predictions via Simulation-based Synthetic Data Augmentation and Multitask Learning
Riccardo Finotello, Daniel L'Hermite, Celine Quéré +3
We consider quantitative analyses of spectral data using laser-induced breakdown spectroscopy. We address the small size of training data available, and the validation of the predi…
HyperPCA: a Powerful Tool to Extract Elemental Maps from Noisy Data Obtained in LIBS Mapping of Materials
Riccardo Finotello, Mohamed Tamaazousti, Jean-Baptiste Sirven
Laser-induced breakdown spectroscopy is a preferred technique for fast and direct multi-elemental mapping of samples under ambient pressure, without any limitation on the targeted…
Deep multi-task mining Calabi-Yau four-folds
Harold Erbin, Riccardo Finotello, Robin Schneider +1
We continue earlier efforts in computing the dimensions of tangent space cohomologies of Calabi-Yau manifolds using deep learning. In this paper, we consider the dataset of all Cal…
Machine learning for complete intersection Calabi-Yau manifolds: a methodological study
Harold Erbin, Riccardo Finotello
We revisit the question of predicting both Hodge numbers and of complete intersection Calabi-Yau (CICY) 3-folds using machine learning (ML), considering both th…
Inception Neural Network for Complete Intersection Calabi-Yau 3-folds
Harold Erbin, Riccardo Finotello
We introduce a neural network inspired by Google's Inception model to compute the Hodge number of complete intersection Calabi-Yau (CICY) 3-folds. This architecture impro…
On the Origin of Divergences in Time-Dependent Orbifolds
Andrea Arduino, Riccardo Finotello, Igor Pesando
We consider time-dependent orbifolds in String Theory and we show that divergences are not associated with a gravitational backreaction since they appear in the open string sector…
2D Fermion on the Strip with Boundary Defects as a CFT with Excited Spin Fields
Riccardo Finotello, Igor Pesando
We consider a two-dimensional fermion on the strip in the presence of an arbitrary number of zero-dimensional boundary changing defects. We show that the theory is still conformal…
The Classical Solution for the Bosonic String in the Presence of Three D-branes Rotated by Arbitrary SO(4) Elements
Riccardo Finotello, Igor Pesando
We consider the classical instantonic contribution to the open string configuration associated with three D-branes with relative rotation matrices in SO(4) which corresponds to the…
