Regularization

Definition
AI-generated

Regularization constrains a model to improve generalization and calibration: L1/L2 penalties shrink coefficients in classical prediction, while dropout, noise injection, weight decay, and early stopping play analogous roles in deep learning on high-dimensional omics inputs.

Why it matters in GWAS

Statistical concepts underpin GWAS significance, effect estimation, relatedness random effects, multiple testing, fine-mapping priors, and post-GWAS multivariate methods; neural predictors of molecular endpoints also need regularization choices reported alongside architecture.

Example usage

"We compared ridge versus lasso SNP polygenic predictors to see which regularization better matched the cross-ancestry validation slope."

Node order. The current term is first. Next come every page linked from Related terms, in the same top-to-bottom order as that list. Then new terms appear in two-hop layers: for each of those direct neighbors (in that same order), their related terms are appended if not already listed. A third pass does the same for two-hop nodes. The walk stops when a fixed maximum number of nodes is reached.
