Gilson Shimizu, Rafael Izbicki, Denis Valle
The Latent Dirichlet Allocation (LDA) model is a popular method for creating mixed-membership clusters. Despite having been originally developed for text analysis, LDA has been use…
CD-split and HPD-split: efficient conformal regions in high dimensions
Rafael Izbicki, Gilson Shimizu, Rafael B. Stern
Conformal methods create prediction bands that control average coverage assuming solely i.i.d. data. Although the literature has mostly focused on prediction intervals, more genera…
Flexible distribution-free conditional predictive bands using density estimators
Rafael Izbicki, Gilson T. Shimizu, Rafael B. Stern
Conformal methods create prediction bands that control average coverage under no assumptions besides i.i.d. data. Besides average coverage, one might also desire to control conditi…
