Evaluation

To evaluate the model against the datasets used in the paper, please install our evaluation toolkit USEB:

bash

pip install useb  # Or git clone and pip install .
python -m useb.downloading all  # Download both training and evaluation data

And then do the evaluation:

python

from sentence_transformers import SentenceTransformer, models
import torch
from useb import run_on

dataset = 'askubuntu'
model_name_or_path = f'kwang2049/TSDAE-{dataset}2nli_stsb'
model = SentenceTransformer(model_name_or_path)
model[1] = models.Pooling(model[0].get_word_embedding_dimension(), pooling_mode='cls')  # Note this model uses CLS-pooling

@torch.no_grad()
def semb_fn(sentences) -> torch.Tensor:
   return torch.Tensor(model.encode(sentences, show_progress_bar=False))

result = run_on(
   dataset,
   semb_fn=semb_fn,
   eval_type='test',
   data_eval_path='data-eval'
)

Training

Please refer to the page of TSDAE training in SentenceTransformers.
