Neural Spectral Capacity ranks architectures beyond parameter and FLOP counts
NSC estimates architectural capacity from weight-matrix spectra, and its dynamic-programming solver finds a budget-constrained design without instantiating a model; tests span seven Transformer and CNN families. It offers a measurable alternative to size-only proxies when choosing architectures.
- What
- Neural Spectral Capacity (NSC) scores neural architectures using the singular-value spectra of their weight matrices.
- Method
- Under standard random initialization, NSC can be computed from an architecture specification alone; NSC-DP uses dynamic programming to maximize it under resource constraints.
- Why it matters
- The method offers engineers an architecture-ranking and optimization approach that does not require model instantiation, data, or gradients.
