sharmapratik88/AIML-Projects ? reverse-engineered prompt

Build me a polished Jupyter notebook project portfolio for my AI and machine learning coursework, organized into separate sections for statistics, supervised learning, ensemble methods, unsupervised learning, feature engineering, recommendation systems, neural networks, computer vision, and NLP.

I want each section to have a clear notebook with cleaned up analysis, simple explanations, useful charts, and model comparisons where relevant. The projects should feel like real end to end case studies, like predicting insurance charges, loan approval, bank term deposit subscription, vehicle classification, concrete strength prediction, and sentiment or sarcasm detection.

Please make the README look professional too, with short descriptions of each project and easy links to the notebooks. Keep it beginner friendly, well structured, and visually clear. If you need to check current notebook or markdown best practices online, go ahead and look them up.
