| ### 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.\ | |
