Large-Scale Quantum Separability Through a Reproducible Machine Learning Lens

Balthazar Casalé, Giuseppe Di Molfetta, Sandrine Anthoine +1

The quantum separability problem consists in deciding whether a bipartite density matrix is entangled or separable. In this work, we propose a machine learning pipeline for finding…

Deep Learning with Kernels through RKHM and the Perron-Frobenius Operator

Yuka Hashimoto, Masahiro Ikeda, Hachem Kadri

Reproducing kernel Hilbert -module (RKHM) is a generalization of reproducing kernel Hilbert space (RKHS) by means of -algebra, and the Perron-Frobenius operator is a line…

Learning in RKHM: a -Algebraic Twist for Kernel Machines

Yuka Hashimoto, Masahiro Ikeda, Hachem Kadri

Supervised learning in reproducing kernel Hilbert space (RKHS) and vector-valued RKHS (vvRKHS) has been investigated for more than 30 years. In this paper, we provide a new twist t…

Implicit Regularization with Polynomial Growth in Deep Tensor Factorization

Kais Hariz, Hachem Kadri, Stéphane Ayache +2

We study the implicit regularization effects of deep learning in tensor factorization. While implicit regularization in deep matrix and 'shallow' tensor factorization via linear an…

Optimality conditions for spatial search with multiple marked vertices

Mathieu Roget, Hachem Kadri, Giuseppe Di Molfetta

We contribute to fulfil the long-lasting gap in the understanding of the spatial search with multiple marked vertices. The theoretical framework is that of discrete-time quantum wa…

Learning primal-dual sparse kernel machines

Riikka Huusari, Sahely Bhadra, Cécile Capponi +2

Traditionally, kernel methods rely on the representer theorem which states that the solution to a learning problem is obtained as a linear combination of the data mapped into the r…

Quantum Perceptron Revisited: Computational-Statistical Tradeoffs

Mathieu Roget, Giuseppe Di Molfetta, Hachem Kadri

Quantum machine learning algorithms could provide significant speed-ups over their classical counterparts; however, whether they could also achieve good generalization remains uncl…

Implicit Regularization in Deep Tensor Factorization

Paolo Milanesi, Hachem Kadri, Stéphane Ayache +1

Attempts of studying implicit regularization associated to gradient descent (GD) have identified matrix completion as a suitable test-bed. Late findings suggest that this phenomeno…

Entangled Kernels -- Beyond Separability

Riikka Huusari, Hachem Kadri

We consider the problem of operator-valued kernel learning and investigate the possibility of going beyond the well-known separable kernels. Borrowing tools and concepts from the f…

Partial Trace Regression and Low-Rank Kraus Decomposition

Hachem Kadri, Stéphane Ayache, Riikka Huusari +2

The trace regression model, a direct extension of the well-studied linear regression model, allows one to map matrices to real-valued outputs. We here introduce an even more genera…

Mapping individual differences in cortical architecture using multi-view representation learning

Akrem Sellami, François-Xavier Dupé, Bastien Cagna +4

In neuroscience, understanding inter-individual differences has recently emerged as a major challenge, for which functional magnetic resonance imaging (fMRI) has proven invaluable.…

Quantum Bandits

Balthazar Casalé, Giuseppe Di Molfetta, Hachem Kadri +1

We consider the quantum version of the bandit problem known as {\em best arm identification} (BAI). We first propose a quantum modeling of the BAI problem, which assumes that both…

Cross-view kernel transfer

Riikka Huusari, Cécile Capponi, Paul Villoutreix +1

We consider the kernel completion problem with the presence of multiple views in the data. In this context the data samples can be fully missing in some views, creating missing col…

QuicK-means: Acceleration of K-means by learning a fast transform

Luc Giffon, Valentin Emiya, Liva Ralaivola +1

K-means -- and the celebrated Lloyd algorithm -- is more than the clustering method it was originally designed to be. It has indeed proven pivotal to help increase the speed of man…

Multi-view Metric Learning in Vector-valued Kernel Spaces

Riikka Huusari, Hachem Kadri, Cécile Capponi

We consider the problem of metric learning for multi-view data and present a novel method for learning within-view as well as between-view metrics in vector-valued kernel spaces, a…
