模型:
TurkuNLP/sbert-cased-finnish-paraphrase
从FinBERT训练的芬兰语BERT模型。可以在4亿个句子的数据集中找到相似度最高的句子的演示 here 。
与HuggingFace文档中的 the English Sentence Transformer 相同。可以通过SentenceTransformer或HuggingFace Transformers进行。
from sentence_transformers import SentenceTransformer sentences = ["Tämä on esimerkkilause.", "Tämä on toinen lause."] model = SentenceTransformer('TurkuNLP/sbert-cased-finnish-paraphrase') embeddings = model.encode(sentences) print(embeddings)
from transformers import AutoTokenizer, AutoModel import torch #Mean Pooling - Take attention mask into account for correct averaging def mean_pooling(model_output, attention_mask): token_embeddings = model_output[0] #First element of model_output contains all token embeddings input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float() return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9) # Sentences we want sentence embeddings for sentences = ["Tämä on esimerkkilause.", "Tämä on toinen lause."] # Load model from HuggingFace Hub tokenizer = AutoTokenizer.from_pretrained('TurkuNLP/sbert-cased-finnish-paraphrase') model = AutoModel.from_pretrained('TurkuNLP/sbert-cased-finnish-paraphrase') # Tokenize sentences encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt') # Compute token embeddings with torch.no_grad(): model_output = model(**encoded_input) # Perform pooling. In this case, mean pooling. sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask']) print("Sentence embeddings:") print(sentence_embeddings)
