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

Alex Timashov

Data labeling is an expensive bottleneck. What if you could hit 95% accuracy with just 100 labels? Discover how semi-supervised learning makes this a reality.

#1 about 6 min

Financial and temporal costs of data labeling

High financial costs and extensive time requirements drive the need for alternatives to fully supervised machine learning.

#2 about 5 min

Core intuition connecting supervised and unsupervised learning

Combining small labeled sets with abundant unlabeled examples bridges the gap between purely supervised and unsupervised methods.

#3 about 3 min

Applying entropy minimization and pseudo labeling

Minimizing classification entropy on unlabeled data helps establish confident decision boundaries in semi-supervised training.

#4 about 4 min

Maintaining class consistency with stochastic image augmentations

Applying random transformations like rotation and cropping to unlabeled images preserves original class identities for consistent training.

#5 about 5 min

Techniques for text augmentation and virtual adversarial attacks

Advanced augmentation strategies like back-translation and virtual adversarial training generate reliable variations for complex text and image datasets.

#6 about 3 min

Leveraging generative models to learn semantic data structures

Generative modeling extracts underlying structural patterns from unlabeled data to substantially improve basic classification boundaries.

#7 about 4 min

Applying variational autoencoders to semi-supervised classification

Integrating variational autoencoders with standard classification models significantly boosts model accuracy despite extremely small labeled sample sizes.

#8 about 1 min

Summarizing the mechanics of semi-supervised frameworks

Effectively merging supervised constraints with expansive unlabelled distributions is the foundation of modern semi-supervised loss functions.
