M.Tech Thesis : ML & Bioinformatics
Built ML-based classification models to predict the efficacy of drugs against Tuberculosis (TB) strains. For a given patient's TB strain with specific mutations, the models predicted drug resistance or susceptibility, reducing reliance on time-consuming lab tests, and increasing the likelihood of effective treatment and patient survival
