Simplicity and complexity of probabilistically defined concepts.
Jacob Feldman · Psychological Review · 2025
: Simple concepts are those that can be approximately recovered from a projection of the concept onto a lower dimensional feature space, while more complex concepts are those that can only be represented by combining features. The framework provides a consistent, coherent, and broadly applicable measure of the complexity of probabilistic concepts. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
