Research Areas
Research Interests
My research interests lie in Machine Learning and Data Science, with a focus on developing intelligent models for data-driven decision making. I am particularly interested in supervised and unsupervised learning, deep learning architectures, and natural language processing for extracting meaningful insights from large-scale, real-world data. My work also explores feature engineering, dimensionality reduction, model interpretability, and performance optimization. I aim to apply these techniques to domains such as healthcare, smart systems, and intelligent automation, emphasizing scalable, ethical, and explainable AI solutions.
