Semi-Supervised Learning with Generative Adversarial Networks Augustus Odena AUGUSTUS. Semi-supervised learning is a set of techniques used to make use of unlabelled data in supervised learning problems (e. PyTorch Geometric (PyG) is a geometric deep learning extension library for PyTorch. semi-supervised image classification - 🦡 Badges Include the markdown at the top of your GitHub README. With that in mind, the technique in which both labeled and unlabeled data is used to train a machine learning classifier is called semi-supervised learning.
