End-to-End Neural Shrinkage of Indefinite Pairwise Correlation Matrices for Small-Cap-Inclusive Portfolios
Christian Bongiorno, Lorenzo Villassero
Small-cap-inclusive equity universes contain recently listed and intermittently traded securities, so enforcing a common look-back discards a substantial fraction of the available…
Discovering Interpretable Biological Concepts in Single-cell RNA-seq Foundation Models
Charlotte Claye, Pierre Marschall, Wassila Ouerdane +2
Single-cell RNA-seq foundation models achieve strong performance on downstream tasks but remain black boxes, limiting their utility for biological discovery. Recent work has shown…
On analysis of problems of mathematical physics with non-Lipschitz boundaries
Anna Rozanova-Pierrat
We review recent advances in solving problems of mathematical physics on domains with irregular boundaries in Rn. We distinguish two frameworks: a measure-free approach in the imag…
Brownian motion on the Fubini extension space and applications
Hamed Amini, Nina H. Amini, Sofiane Chalal +1
We study a family of essentially pairwise independent Brownian motions indexed by a continuum of labels and show how the Fubini extension framework provides a rigorous way to repre…
Graphon Quantum Filtering Systems
Hamed Amini, Nina H. Amini, Sofiane Chalal +1
We consider a non-exchangeable system of interacting quantum particles with mean-field type interactions, subject to continuous measurement on dense graphs. In the mean-field limit…
Poincar{é}-Steklov operator and Calder{ó}n's problem on extension domains
Gabriel Claret, Michael Hinz, Anna Rozanova-Pierrat
We consider Calder{ó}n's problem on a class of Sobolev extension domains containing non-Lipschitz and fractal shapes. We generalize the notion of Poincar{é}-Steklov (Dirichlet-to-N…
