Explanation

Explanation pages are understanding-oriented: they provide background, theory, and design rationale. They answer the question "why?" rather than "how?".

Available Explanations

Deep Sets Theory

Formal statements of Theorem 2 (permutation invariance + universal approximation) and Lemma 3 (permutation equivariance), intuitive explanations, and proof sketches.

Architecture Decisions

Design rationale behind the implementation: why _masked_pool uses −∞ for max pooling, why nn.ModuleList is used instead of nn.Sequential in DeepSetsEquivariant, the mathematics of FiLM conditioning, and a comparison of Deep Sets to alternative approaches.
