Probabilistic feature extraction, dose statistic prediction and dose mimicking for automated radiation therapy treatment planning

no code implementations • 24 Feb 2021 • Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

We show that the features extracted by the variational autoencoder capture geometric information of substantial relevance to the dose statistic prediction problem and are related to dose statistics in a more regularized fashion than hand-crafted features.

We present a new nonparametric mixture-of-experts model for multivariate regression problems, inspired by the probabilistic k-nearest neighbors algorithm.
