+## Model Description
+ 
+BRIO: Bringing Order to Abstractive Summarization
+ 
+- **Developed by:** Yale LILY Lab
+- **Shared by [Optional]:** Hugging Face
+- **Model type:** PEGASUS
+- **Language(s) (NLP):** Text2Text Generation
+- **License:** More information needed

+ 
+# Uses
+ 
+## Direct Use
+This model can be used for the task of Text2Text Generation
+ 
+## Downstream Use [Optional]
+ 
+The model creators note in the [associated paper](https://arxiv.org/abs/2203.16804)
+> It is possible to apply our method in a reinforcement learning setting, where the candidate summaries are dynamically generated. 
+ 
+## Out-of-Scope Use
+ 
+ 
+The model should not be used to intentionally create hostile or alienating environments for people. 
+ 
+# Bias, Risks, and Limitations
+ 
+ 
+Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. (2021)](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. (2021)](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.
+ 
+ 
+## Recommendations
+ 
+ 
+Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

+ 
+# Training Details
+ 
+## Training Data
+The model creators note in the [associated paper](https://arxiv.org/abs/2203.16804)
+> CNNDM4: is a large scale news dataset.
+Nallapati et al: we treat the news articles as the source documents and the associated highlights as the summaries. 
+XSum5: is a highly abstractive dataset of articles from the British Broadcasting Corporation (BBC). NYT6: contains articles from the New York Times and the associated summaries
+ 
+## Training Procedure
+ 
+ 
+### Preprocessing
+ The model creators note in the [associated paper](https://arxiv.org/abs/2203.16804)
+ > We follow Kedzie et al. (2018) for data preprocessing and splitting, and use the associated archival abstracts as the summaries

+# Model Examination
+The model creators note in the [associated paper](https://arxiv.org/abs/2203.16804)
+We attribute BRIO-Ctr’s superior performance to its use of the same model architecture (BART) for both candidate generation and scoring, while SimCLS uses RoBERTa as the evaluation model. As a result, BRIO-Ctr maximizes the parameter sharing between the two stages, and preserves the power of the Seq2Seq model pre-trained on the same dataset.

+# Environmental Impact
+ 
+ 
+Carbon emissions can be estimated using the [Machine Learning Impact calculator](https://mlco2.github.io/impact#compute) presented in [Lacoste et al. (2019)](https://arxiv.org/abs/1910.09700).
