### Classifier of COVID-19 variant (omicron, delta)
This model takes complete neucleotide sequence as input and return its COVID variant (omicron and delta only)
## Model training
The model was pretrained with RoBERTa config, using all complete necleotide genome of COVID-19 on NCBI. The finetuning step uses ~10000 labeled training data for a binary classification task.\
