Twin Neural Network Regression is a Semi-Supervised Regression Algorithm

no code implementations11 Jun 2021 Sebastian J. Wetzel, Roger G. Melko, Isaac Tamblyn

Twin neural network regression (TNNR) is a semi-supervised regression algorithm, it can be trained on unlabelled data points as long as other, labelled anchor data points, are present.
