pub struct TextClassifierDatasetBuilder<'a, T: Class, E: Embedder> { /* private fields */ }
Expand description
A builder for TextClassifier
.
§Example
// Create a dataset for the classifier
let bert = Bert::new().await?;
let mut dataset = TextClassifierDatasetBuilder::<MyClass, _>::new(&bert);
for question in ["What is the author's name?", "What is the author's age?"] {
dataset.add(question, MyClass::Person).await?;
}
for question in [
"What is the capital of France?",
"What is the capital of England?",
] {
dataset.add(question, MyClass::Thing).await?;
}
Implementations§
Source§impl<'a, T: Class, E: Embedder> TextClassifierDatasetBuilder<'a, T, E>
impl<'a, T: Class, E: Embedder> TextClassifierDatasetBuilder<'a, T, E>
Sourcepub fn new(embedder: &'a E) -> Self
pub fn new(embedder: &'a E) -> Self
Creates a new TextClassifierDatasetBuilder
.
Sourcepub async fn add(
&mut self,
text: impl ToString,
class: T,
) -> Result<(), E::Error>
pub async fn add( &mut self, text: impl ToString, class: T, ) -> Result<(), E::Error>
Adds a new example to the dataset.
Sourcepub async fn extend(
&mut self,
examples: impl IntoIterator<Item = (impl ToString, T)>,
) -> Result<(), E::Error>
pub async fn extend( &mut self, examples: impl IntoIterator<Item = (impl ToString, T)>, ) -> Result<(), E::Error>
Add many examples to the dataset at once. This may be faster than adding each example individually depending on the embedding model.
§Example
// Create a dataset for the classifier
