It tackles the distortion issue of statistics estimated from the dataset with outliers by a re-sampling technique and accounts, rationally, for the statistical uncertainty by Bayesian machine learning. Moreover, the proposed approach also suggests an exclusive method to determine outlying components of ...
details Abstract In this paper we characterize the performance of linear models trained via widely-usedsparsemachine learning algorithms. We build polygenic scores and examine performance as a function of training set size, genetic ancestral background, and training method. We show that predictor perfor...

More recently, a Bayesian framework was used to select the relevant features along the pathway from gene to imaging and then to symptom21. It is worth noting that both models treated diagnosis information as binary status (e.g., AD and normal control (NC)) for imaging genetic association ...
