On an extended interpretation of linkage disequilibrium in genetic case-control association studies.

abstract：:With the increasing availability of experimental data on gene interactions, modeling of gene regulatory pathways has gained special attention. Gradient descent algorithms have been widely used for regression and classification applications. Unfortunately, results obtained after training a model by gradient descent are...
