Ongoing Projects
The aim of this project is to create a low-dimensional representation of SARS-CoV-2 spike protein sequences using an autoencoder neural network. Then, the low dimensional representation of sequences should be clustered using popular clustering algorithms such as TSNE and UMAP to explore if the original differences in sequences belonging to different clades (categories of sequences) are also maintained in lower dimensions.

SARS-COV2 sequences mutate to multiple variants categorized into lineages and clades, some of which alter the pathogenicity of the virus making it more virulent. Using generative adversarial neural networks, artificial sequences can be generated using the knowledge of the evolution of SARS-COV2 sequences in the past. Ideally, the neural network should learn the ‘edit’ mechanism of the sequences that evolved in the past and should generate sequences based on the learned knowledge. The generated sequences should be compared with the true sequences to see how good the neural network performs.
