    pub cell_topic: Mat<F>,

Expand description

A fitted LDA model.

Fields§

§cell_topic: Mat<F>

Topic proportions per document, shape (k, n_docs). Columns sum to one, so a document’s topic vector is one contiguous column.

§topic_region: Mat<F>

Term probabilities per topic, shape (n_terms, k). Columns sum to one, so a topic’s term vector is one contiguous column.

§bound: F

Final variational bound (ELBO). Higher is better.

§perplexity: F

Per-token perplexity, exp(-bound / total_tokens). Lower is better.

§n_iter: usize

Outer iterations actually run.

§converged: bool

Whether the relative bound change fell below tol.
