Research Contributions

During my PhD, I proposed several performance measures for better estimating the predictions of the software defect prediction models. It is of first kind to propose such measures, so that, any researcher working in the area of software defect prediction, can make use of these performance measures. In addition, I am working on providing the real-world feasibility of the developed ML models. This is essential because, ML/DL/GenAI is not the solution for every problem!!!
