Replica analysis of overfitting in generalized linear models
ACC Coolen, M Sheikh, A Mozeika +2
Nearly all statistical inference methods were developed for the regime where the number of data samples is much larger than the data dimension . Inference protocols such as…

Analysis of overfitting in the regularized Cox model
M Sheikh, A. C. C. Coolen
The Cox proportional hazards model is ubiquitous in the analysis of time-to-event data. However, when the data dimension p is comparable to the sample size , maximum likelihood…

Accurate Bayesian Data Classification without Hyperparameter Cross-validation
M Sheikh, A C C Coolen
We extend the standard Bayesian multivariate Gaussian generative data classifier by considering a generalization of the conjugate, normal-Wishart prior distribution and by deriving…
