symptom_encoder_v8

Uso (Sentence-Transformers)

Instalar la biblioteca sentence-transformers:

pip install -U sentence-transformers

Luego, puedes usar el modelo de la siguiente manera:

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('symptom_encoder_v8')
embeddings = model.encode(sentences)
print(embeddings)

Uso (HuggingFace Transformers):

from transformers import AutoTokenizer, AutoModel
import torch

# Mean Pooling - Tome la máscara de atención en cuenta para el promedio correcto
def mean_pooling(model_output, attention_mask):
    token_embeddings = model_output[0] # Primer elemento de model_output contiene todas las embeddings de tokens
    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)

# Oraciones para las que queremos embeddings de sentencias
sentences = ['This is an example sentence', 'Each sentence is converted']

# Cargar modelo desde HuggingFace Hub
tokenizer = AutoTokenizer.from_pretrained('symptom_encoder_v8')
model = AutoModel.from_pretrained('symptom_encoder_v8')

# Tokenizar oraciones
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')

# Computar embeddings de tokens
with torch.no_grad():
    model_output = model(**encoded_input)

# Realizar pooling. En este caso, mean pooling.
sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])

print("Embeddings de sentencias:")
print(sentence_embeddings)
