Fundamental operating regimes, hyper-parameter fine-tuning and glassiness: towards an interpretable replica-theory for trained restricted Boltzmann machines
Alberto Fachechi, Elena Agliari, Miriam Aquaro +2
We consider restricted Boltzmann machines with a binary visible layer and a Gaussian hidden layer trained by an unlabelled dataset composed of noisy realizations of a single ground…
Observable asymptotics of regularized Cox regression models with standard Gaussian designs: a statistical mechanics approach
Emanuele Massa, Anthony Coolen
We study the asymptotic behaviour of the Regularized Maximum Partial Likelihood Estimator (RMPLE) in the proportional limit, considering an arbitrary convex regularizer and assumin…
Bayesian Federated Inference for Survival Models
Hassan Pazira, Emanuele Massa, Jetty AM Weijers +2
In cancer research, overall survival and progression free survival are often analyzed with the Cox model. To estimate accurately the parameters in the model, sufficient data and, m…
Replica analysis of overfitting in regression models for time to event data: the impact of censoring
Emanuele Massa, Alexander Mozeika, Anthony Coolen
We use statistical mechanics techniques, viz. the replica method, to model the effect of censoring on overfitting in Cox's proportional hazards model, the dominant regression metho…
Correction of overfitting bias in regression models
Emanuele Massa, Marianne Jonker, Kit Roes +1
Regression analysis based on many covariates is becoming increasingly common. However, when the number of covariates is of the same order as the number of observations , max…
Immune networks: multi-tasking capabilities near saturation
Elena Agliari, Alessia Annibale, Adriano Barra +2
Pattern-diluted associative networks were introduced recently as models for the immune system, with nodes representing T-lymphocytes and stored patterns representing signalling pro…
