| # Basic Information | |
| This is the Dr. Decr model used in XOR-TyDi leaderboard task 1 whitebox submission. | |
| https://nlp.cs.washington.edu/xorqa/ | |
| The detailed implementation of the model can be found in: | |
| https://arxiv.org/pdf/2112.08185.pdf | |
| Source code to train the model can be found via PrimeQA's IR component: | |
| https://github.com/primeqa/primeqa/tree/main/examples/drdecr | |
| It is a Neural IR model built on top of the ColBERTv1 api and not directly compatible with Huggingface API. The inference result on XOR Dev dataset is: | |

| # Limitations and Bias | |
| This model used pre-trained XLM-R base model and fine tuned on 7 languages in XOR-TyDi leaderboard. The performance of other languages was not tested. | |
| Since the model was fine-tuned on a large pre-trained language model XLM-Roberta, biases associated with the pre-existing XLM-Roberta model may be present in our fine-tuned model, Dr. Decr | |
