Contains core utilities.

Classes

RetryOptions: Options to pass into retryClient to control the retry behavior.

calculateSimilarity(List<double> embedding, List<List<double>> embeddings, {double similarityFunction(List<double> a, List<double> b) = cosineSimilarity}) → List<double>: Calculates the similarity between an embedding and a list of embeddings.
chunkList<T>(List<T> arr, {required int chunkSize}) → List<List<T>>: Chunk a list into smaller list of a specified size.
cosineSimilarity(List<double> a, List<double> b) → double: Measures the cosine of the angle between two vectors in a vector space. It ranges from -1 to 1, where 1 represents identical vectors, 0 represents orthogonal vectors, and -1 represents vectors that are diametrically opposed.
getIndexesMostSimilarEmbeddings(List<double> embedding, List<List<double>> embeddings, {double similarityFunction(List<double> a, List<double> b) = cosineSimilarity}) → List<int>: Returns a sorted list of indexes of embeddings that are most similar to the provided embedding (in descending order, most similar first).
reduce<Type>(Iterable<Type> input) → Type: Reduces a list of objects to a single object by concatenating them.
retryClient<T>({required RetryOptions options, required FutureOr<T> fn()}) → FutureOr<T>: A client that handles retry logic for a given function.
