> The machine-learning method achieves 100 percent accurate classification of the COVID-19 sequences and more importantly, discovers the most relevant relationships among more than 5,000 viral genomes again within minutes. I only have a basic understanding of ML but isn't 100% accuracy this early on (limited dataset) an indicator of overfitting?
