We study the multiclass classification problem where the features come from the mixture of time-homogeneous diffusions.

Regression with reject option and application to kNN

no code implementations NeurIPS 2020 Christophe Denis, Mohamed Hebiri, Ahmed Zaoui

We provide a semi-supervised estimation procedure of the optimal rule involving two datasets: a first labeled dataset is used to estimate both regression function and conditional variance function while a second unlabeled dataset is exploited to calibrate the desired rejection rate.
