 Carptriever-1 is a `bert-large-uncased` retrieval model trained with contrastive learning via a momentum contrastive (MoCo) mechanism following the work of G. Izacard et al. in ["Contriever: Unsupervised Dense Information Retrieval with Contrastive Learning"](https://arxiv.org/abs/2112.09118).

+Carptriever-1 is pre-trained on a de-duplicated subset of [The Pile](https://pile.eleuther.ai/), a large and diverse dataset created by EleutherAI for language model training. This subset was created through a [Minhash LSH](http://ekzhu.com/datasketch/lsh.html) process using a threshold of `0.87`.

 Note that degradation in performance, relative to the Contriever model, was expected given the much broader diversity of our training dataset. We plan on addressing this in future updates with architectural improvements and view Carptriever-1 as our first iteration in the exploratory phase towards better language-embedding models.
