3. Self-Supervised Learning: Unlocking AI from Unlabeled Data Oceans
Self-supervised learning (SSL) is a machine learning technique where models generate their own supervisory signals from unlabeled data, eliminating the need for costly human annotations. By creating “pretext tasks”—like predicting masked parts of an image or sentence—the model learns rich representations, which can then be fine-tuned for specific downstream tasks. This contrasts with supervised learning’s reliance on labeled datasets, making SSL scalable for vast, raw data sources.
Pioneers include Meta (formerly Facebook) with models like DINO for vision and Google’s BERT for language, which pre-train on massive corpora. OpenAI incorporates SSL in GPT variants, while academic leaders like Yann LeCun at NYU advance theoretical foundations.
