torcharrow.functional.get_cosine_similarity

torcharrow.functional.get_cosine_similarity(input_ids: ListColumn, input_id_scores: ListColumn, matching_ids: ListColumn, matching_id_scores: ListColumn)

返回由input_ids加权定义的向量与由matching_ids加权定义的向量之间的余弦值

Parameters:

• input_ids (第一个ID列表) –

• input_ids_scores (scores (weights) of input_ids) –

• matching_ids (第二个ID列表) –

• matching_ids_scores (scores (weights) of matching_ids) –

示例

>>> import torcharrow as ta
>>> from torcharrow import functional
>>> input_ids = ta.column([[1, 2, 3]])
>>> input_id_scores = ta.column([[1.0,2.0,3.0]])
>>> matching_ids = ta.column([[1,2,3]])
>>> matching_id_scores = ta.column([[5.0,4.0,3.0]])
>>> functional.get_cosine_similarity(input_ids, input_id_scores, matching_ids, matching_id_scores)
