Awesome Semi-Supervised Learning
Introduction
The Awesome Semi-Supervised Learning project is a comprehensive repository that gathers an extensive list of resources focused on the field of semi-supervised learning (SSL). This project is inspired by other celebrated lists like awesome-deep-vision, awesome-deep-learning-papers, and awesome-self-supervised-learning. The goal is to provide researchers, students, and practitioners with a curated collection of SSL resources.
Background
What is Semi-Supervised Learning?
Semi-supervised learning is a special type of machine learning used for classification. Traditional classification methods rely solely on labeled data, where human annotators label examples, making them time-consuming and costly. Unlabeled data, on the other hand, is easier to collect but historically underutilized. Semi-supervised learning leverages both labeled and unlabeled data to enhance model performance. This approach reduces the need for labeling efforts and increases accuracy, making it a valuable technique in both theoretical and practical applications.
Diverse Methods in Semi-Supervised Learning
Numerous methods have been developed for semi-supervised learning. Some common techniques include:
- EM with Generative Mixture Models
- Self-Training
- Consistency Regularization
- Co-Training
- Transductive Support Vector Machines
- Graph-Based Methods
With the rise of deep learning, many of these methods have been adjusted to fit into existing deep learning frameworks, taking full advantage of the abundance of unlabeled data.
Utilization of Unlabeled Data
Semi-supervised learning methods exploit unlabeled data by modifying or reprioritizing hypotheses derived from labeled data. While not all methods rely on probabilistic models, those that do represent hypotheses as p(y|x) and unlabeled data as p(x), showing how p(x) affects p(y|x). Generative models like mixture models with EM fall into this category. Discriminative methods, such as transductive SVMs, Gaussian processes, and graph-based techniques, adjust traditional training by incorporating p(x), thus assuming a shared parameter space between p(y|x) and p(x).
