Semi-Supervised Learning. How to overcome the lack of labels

Semi-supervised learning, an innovative approach in machine learning, strategically positions itself between the realms of supervised and unsupervised learning. This methodology uniquely utilizes a combination of a small portion of labeled data and a substantially larger set of unlabeled data for model training. Its significant advantage lies in scenarios where gathering a fully labeled dataset is prohibitively costly or logistically unfeasible. By blending the directive nature of labeled data with the extensive insights of unlabeled data, semi-supervised learning offers a practical, cost-effective solution for comprehensive model training, especially in data-scarce environments.
