 The project aims to train sentence embedding models on very large sentence level datasets using a self-supervised 
 contrastive learning objective. We used the pretrained ['mpnet-base'](https://huggingface.co/microsoft/mpnet-base) model and fine-tuned in on a 
-1B sentence pairs dataset. We use a contrastive learning objective: given a sentence from the pair, the model should predict which out of a set of randomly sampled other sentences, was actually paired with it in our dataset.

 ### Training data
 
-We use the concatenation from multiple datasets to fine-tune our model. The total number of sentence pairs is above 1 billion sentences.
+We use the concatenation from multiple datasets to fine-tune our model. The total number of sentence pairs is above 700M sentences.
 We sampled each dataset given a weighted probability which configuration is detailed in the `data_config.json` file.
+We only use the first context response when building the dataset.
