What is cocodr-base-msmarco?
COCO-DR Base MS MARCO is a sophisticated dense retrieval model built on BERT-base architecture, specifically designed to combat distribution shifts in zero-shot scenarios. The model has been pretrained on the BEIR corpus and fine-tuned on the MS MARCO dataset, implementing contrastive and distributionally robust learning approaches.
Implementation Details
The model utilizes the BERT-base architecture with 110M parameters and can be easily integrated using the HuggingFace transformers library. It generates dense embeddings for text sequences using the [CLS] token output from the final layer.
