Lesson 06: The Compression Algorithm

Описание: 🧠 Lesson 06: The Compression Algorithm

Your brain doesn't learn from reading — it learns from getting things wrong. When you generate an answer from memory and compare it to reality, the mismatch creates a targeted error signal. That signal tells your brain EXACTLY where to update. No error signal? No update. No learning.

Roediger & Karpicke (2006) found that students who tested themselves retained ~50% more than those who re-read the same material. Same content. Same time. Radically different results. The test isn't the assessment — it's the learning event itself.

In this lesson, we explore:
• The Generation Effect — why producing output beats passive review (Slamecka & Graf, 1978)
• The Testing Effect — how retrieval creates dramatically better long-term retention
• The Error Loop — Predict → Compare → Error → Update
• Why "Desirable Difficulty" means struggle is the feature, not the bug (Bjork, 1994)
• The direct parallel to AI loss functions and backpropagation
• Practical strategies for building error correction into any learning workflow
