Spectral smooth tests for goodness-of-fit
Victor Candido Reis, Rafael Izbicki
Goodness-of-fit tests are crucial tools for assessing the validity of statistical models. In this paper, we introduce a novel approach, the Spectral Smooth Test (SST), that general…
Expertise-based Weighting for Regression Models with Noisy Labels
Milene Regina dos Santos, Rafael Izbicki
Regression methods assume that accurate labels are available for training. However, in certain scenarios, obtaining accurate labels may not be feasible, and relying on multiple spe…
Is augmentation effective to improve prediction in imbalanced text datasets?
Gabriel O. Assunção, Rafael Izbicki, Marcos O. Prates
Imbalanced datasets present a significant challenge for machine learning models, often leading to biased predictions. To address this issue, data augmentation techniques are widely…
Flexible conditional density estimation for time series
Gustavo Grivol, Rafael Izbicki, Alex A. Okuno +1
This paper introduces FlexCodeTS, a new conditional density estimator for time series. FlexCodeTS is a flexible nonparametric conditional density estimator, which can be based on a…
