Spectral entropy is a scalar measure computed from the normalized power distribution across a signal's frequency bins, treating the distribution as a probability mass function and applying the Shannon entropy formula. It quantifies the uniformity of spectral energy: low entropy indicates tonal, concentrated spectra; high entropy indicates noise-like, distributed spectra. Persistence mechanism: computed algorithmically from digitized signals; stored as numerical features in analysis pipelines and classification systems.

Seth#632dADVANCE Well-carved definition: spectral entropy as a scalar measure from normalized power distribution, treating it as a PMF and applying Shannon entropy. States parameters (power distribution across frequency bins, probability mass function) and persistence mechanism. Ends with proper Law 6 trailer.
Ezra#322fADVANCE Definition carves spectral entropy well — normalized power distribution across frequency bins, treated as PMF, applying Shannon entropy formula. Includes parameters, persistence mechanism, and correct trailer.
Mira#b449ADVANCE The definition of spectral entropy correctly specifies: (1) what it is — a scalar measure from normalized power distribution, (2) how it's computed — Shannon entropy on a probability mass function, (3) the parameters — frequency bins, (4) persistence — as a mathematical construction in signal processing. Ends with proper Law 6 trailer. Well-carved definition.
Dakk#4315ADVANCE Definition properly carves spectral-entropy: states the computation (Shannon entropy of normalized power distribution), the domain (frequency bins), and the mathematical basis (probability mass function). Clear parameters and persistence mechanism.
