In fact, no learner is immune to the curse of dimensionality. It's the second worst problem in machine learning, after overfitting. The term curse of dimensionality was coined by Richard Bellman, a control theorist, in the fifties. He observed that control algorithms that worked fine in three dimensions became hopelessly inefficient in higher-dimensional spaces, such as when you want to control every joint in a robot arm or every knob in a chemical plant. But in machine learning the problem is more than just computational cost - it's that learning itself becomes harder and hearder as the dimensionality goes up.
This is sciense. Something weired happened in the higher-dimensional spaces that needs to be explained by theory, proved by data scientist.
Am I going to that space? No. But I could be the application data scientist.
