On the Slow Convergence to Trivial Solutions of Algorithms for Hard Optimization Problems

Ali Hussaini Umar, Jean Barbier, Matthieu Jonckheere +1

Hard combinatorial optimization problems, many of which are NP-hard, present fundamental algorithmic challenges. Average-case analysis on random instances has emerged as a powerful…

The Effect of Label Noise on the Information Content of Neural Representations

Ali Hussaini Umar, Franky Kevin Nando Tezoh, Jean Barbier +2

In supervised classification tasks, models are trained to predict a label for each data point. In real-world datasets, these labels are often noisy due to annotation errors. While…

Information-theoretic reduction of deep neural networks to linear models in the overparametrized proportional regime

Francesco Camilli, Daria Tieplova, Eleonora Bergamin +1

We rigorously analyse fully-trained neural networks of arbitrary depth in the Bayesian optimal setting in the so-called proportional scaling regime where the number of training sam…

Machine learning for cerebral blood vessels' malformations

Irem Topal, Alexander Cherevko, Yuri Bugay +5

Cerebral aneurysms and arteriovenous malformations are life-threatening hemodynamic pathologies of the brain. While surgical intervention is often essential to prevent fatal outcom…
