Why does high dimensional space become counter-intuitive?
Updated May 15, 2026
Short answer
Because geometric intuition from 2D/3D fails in higher dimensions.
Deep explanation
In high dimensions, volume distribution, distances, and angles behave very differently. Most of the volume shifts toward boundaries, making intuition from low-dimensional geometry misleading.
Real-world example
ML models trained on image embeddings behaving unpredictably.
Common mistakes
- Assuming 3D intuition applies to high-dimensional ML spaces.
