Kernel trick
Kernel trick: A technique computing dot products in an implicit feature space without explicitly constructing every coordinate. It enables nonlinear boundaries with kernel methods. Kernel choice defines similarity and inductive bias, without removing validation and cost. This perspective connects the definition with practical behaviour in artificial intelligence systems.
