class jina.executors.evaluators.embedding.euclidean.EuclideanEvaluator(*args, **kwargs)[source]

Bases: jina.executors.evaluators.embedding.BaseEmbeddingEvaluator

A EuclideanEvaluator evaluates the distance between actual and desired embeddings computing the euclidean distance between them

metric = 'EuclideanDistance'

Get the name of the evaluation metric
