Abstract Sim Sentence

🚀 抽象文書記述マッピングモデル

このモデルは、抽象的な文の記述を、その記述に適合する文にマッピングするためのものです。Wikipediaのデータを使って学習されています。load_finetuned_model を使ってクエリエンコーダと文エンコーダを読み込み、encode_batch() を使って文をエンコードすることができます。

💻 使用例

基本的な使用法

from transformers import AutoTokenizer, AutoModel
import torch
from typing import List
from sklearn.metrics.pairwise import cosine_similarity

def load_finetuned_model():


        sentence_encoder = AutoModel.from_pretrained("biu-nlp/abstract-sim-sentence")
        query_encoder = AutoModel.from_pretrained("biu-nlp/abstract-sim-query")
        tokenizer = AutoTokenizer.from_pretrained("biu-nlp/abstract-sim-sentence")

        return tokenizer, query_encoder, sentence_encoder


def encode_batch(model, tokenizer, sentences: List[str], device: str):
    input_ids = tokenizer(sentences, padding=True, max_length=512, truncation=True, return_tensors="pt",
                          add_special_tokens=True).to(device)
    features = model(**input_ids)[0]
    features =  torch.sum(features[:,1:,:] * input_ids["attention_mask"][:,1:].unsqueeze(-1), dim=1) / torch.clamp(torch.sum(input_ids["attention_mask"][:,1:], dim=1, keepdims=True), min=1e-9)
    return features

                        ]

all_sentences = relevant_sentences + irrelevant_sentences
query = "<query>: A company is a part of a larger company."
    
embeddings = encode_batch(sentence_encoder, tokenizer, all_sentences, "cpu").detach().cpu().numpy()
