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…
Large time effective kinetics -functions for quantum (2 + p)-spin glass II: Effective vertex expansion, local potential approximation and symmetries
Bêm-Biéri Barthélémy Natta, Vincent Lahoche, Dine Ousmane Samary +1
This paper aims to study the functional renormalization group for quantum -spin dynamics of a -vector . By fixing the gauge symmetry in the co…
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…
Functional Renormalization Group for a Rank-4 Renormalizable Tensorial Group Field Theory with Derivative Necklace Couplings
Seke Fawaaz Zime Yerima, Vincent Lahoche, Dine Ousmane Samary
We apply the functional renormalization group to an Abelian Group Field Theory extended beyond the branched-polymer (melonic) sector by including interactions that are subdominant…
Large time effective kinetics -functions for quantum (2+p)-spin glass
Vincent Lahoche, Dine Ousmane Samary, Parham Radpay
This paper examines the quantum -spin dynamics of a -vector through the lens of renormalization group (RG) theory. The RG is based on a coars…
Stochastic dynamics for group field theories II: Methods for nonequilibrium renormalization group
Vincent Lahoche, Dine Ousmane Samary
This paper is a continuation of our earlier work, which aimed to develop methods for understanding the renormalization group of tensorial group field theories within the stochastic…
