Struct TrainingExample 

pub struct TrainingExample {
    pub id: Uuid,
    pub context_embeddings: Vec<Vec<f32>>,
    pub message_embedding: Vec<f32>,
    pub labels: IntentLabels,
    pub metadata: ExampleMetadata,
}

A single training example for intent classification

Contains the input embeddings, soft labels from teacher, and metadata for traceability and debugging.

Fields

id: Uuid

Unique identifier for this example

context_embeddings: Vec<Vec<f32>>

Context embeddings from the last N messages

Each inner Vec represents an embedding vector for one message. Order: oldest to newest (chronological).

message_embedding: Vec<f32>

Embedding of the current message to classify

labels: IntentLabels

Soft labels from teacher model

metadata: ExampleMetadata

Metadata about this example

Implementations

impl TrainingExample

pub fn new( context_embeddings: Vec<Vec<f32>>, message_embedding: Vec<f32>, labels: IntentLabels, ) -> Self

Create a new training example with minimal metadata

pub fn with_id( id: Uuid, context_embeddings: Vec<Vec<f32>>, message_embedding: Vec<f32>, labels: IntentLabels, ) -> Self

Create a new training example with specific ID

pub fn with_metadata(self, metadata: ExampleMetadata) -> Self

Set metadata for this example

pub fn embedding_dim(&self) -> usize

Get the embedding dimension (from message embedding)

pub fn context_size(&self) -> usize

Get the context window size (number of context messages)

pub fn validate(&self) -> Result<(), String>

Validate the example structure

pub fn dominant_intent(&self) -> (&'static str, f32)

Get the dominant intent (highest probability label)
