<!-- Provide a quick summary of what the model is/does. -->
This model is used to predict ACE2 binding affinities with mutant SARSCoV-2 Omicron XBB.1.5 variants spike receptor-binding domain (RBD). 

### Task type
protein level regression

### Dataset description
The dataset is from [Deep mutational scans of XBB.1.5 and BQ.1.1 reveal ongoing epistatic drift during SARSCoV-2 evolution](https://doi.org/10.1371/journal.ppat.1011901).

Label means binding affinities level, ranging from minus infinity to positive infinity.
Zero means no affinity, lager means higher affinity and smaller means lower affinity.
### Model input type
Amino acid sequence
