BiEncoder Regression Model
This model is a BiEncoder architecture that outputs similarity scores between text pairs.
Model Details
- Base Model: bert-base-uncased
- Task: Regression
- Architecture: BiEncoder with cosine similarity
- Loss Function: contrastive
Usage
from transformers import AutoTokenizer, AutoModel
from modeling import BiEncoderModelRegression
# Load model components
tokenizer = AutoTokenizer.from_pretrained("minoosh/bert-reg-biencoder-contrastive")
base_model = AutoModel.from_pretrained("bert-base-uncased")
model = BiEncoderModelRegression(base_model, loss_fn="contrastive")
# Load weights
state_dict = torch.load("pytorch_model.bin")
model.load_state_dict(state_dict)
# Prepare inputs
texts1 = ["first text"]
texts2 = ["second text"]
inputs = tokenizer(
texts1, texts2,
padding=True,
truncation=True,
return_tensors="pt"
)
# Get similarity scores
outputs = model(**inputs)
similarity_scores = outputs["logits"]
Metrics
