Coxeter Combinatorics For Sum Formulas In The Representation Theory Of Algebraic Groups
Let G be a simple algebraic group over an algebraically closed field F of characteristic p >= h, the Coxeter number of G. We observe an easy 'recursion formula' for computing the Jantzen sum formula of a Weyl module with p-regular highest weight. We also d ...
AMER MATHEMATICAL SOC2022Learning V1 Simple Cells with Vector Representation of Local Content and Matrix Representation of Local Motion
This paper proposes a representational model for image pairs such as consecutive video frames that are related by local pixel displacements, in the hope that the model may shed light on motion perception in primary visual cortex (V1). The model couples the ...
ASSOC ADVANCEMENT ARTIFICIAL INTELLIGENCE2022From Undercomplete to Sparse Overcomplete Autoencoders to Improve LF-MMI Speech Recognition
Hervé Bourlard, Selen Hande Kabil
Starting from a strong Lattice-Free Maximum Mutual Information (LF-MMI) baseline system, we explore different autoencoder configurations to enhance Mel-Frequency Cepstral Coefficients (MFCC) features. Autoencoders are expected to generate new MFCC features ...
ISCA-INT SPEECH COMMUNICATION ASSOC2022Reduced order modelling of nonaffine problems on parameterized NURBS multipatch geometries
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution explores the combined capabilities of reduced basis methods and IsoGeometric Analysis (IGA) in the context of parameterized partial differential equations. The introduction of IGA enables a unified simulation framework based on a single g ...
2022Pure Isotropic Proton Solid State NMR
David Lyndon Emsley, Daria Torodii, Pinelopi Moutzouri, Bruno Simões de Almeida
Resolution in proton solid state magic angle sample spinning (MAS) NMR is limited by the intrinsically imperfect nature of coherent averaging induced by either MAS or multiple pulse sequence methods. Here, we suggest that instead of optimizing and perfecti ...
