cosineSimilarity method

@override Future<double> cosineSimilarity(Embedding a, Embedding b)

Compares the similarity between two Embedding values. Identical embeddings will yield a similarity value of 1.0.

Implementation

@override
Future<double> cosineSimilarity(Embedding a, Embedding b) async {
  await _ready;
  _sendPort.send(_EmbedderTask.cosineSimilarity(a, b));
  while (true) {
    final response = await _events.next;
    if (response is double) {
      return response;
    } else if (response is String) {
      _log.fine(response);
    } else {
      throw Exception(
        'Unexpected cosine similarity result of type ${response.runtimeType} : $response',
      );
    }
  }
}
