Struct TopicModel 

pub struct TopicModel {
    pub topic_id: u64,
    pub centroid: Vec<f32>,
    pub member_count: u64,
    pub total_weight: f64,
    pub label: String,
}

A latent topic represented as a running centroid of assigned embeddings.

Fields

topic_id: u64

Unique identifier for this topic.

centroid: Vec<f32>

Running mean of all embeddings assigned to this topic.

member_count: u64

Number of documents assigned to this topic.

total_weight: f64

Sum of assignment weights (cosine similarities at assignment time).

label: String

Human-readable label (defaults to "topic_<id>").

Implementations

impl TopicModel

pub fn coherence(&self) -> f64

Coherence measure: member_count / (1.0 + total_weight).

A higher value indicates a more focused (tight) topic.

Trait Implementations

impl Clone for TopicModel

fn clone(&self) -> TopicModel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TopicModel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
