animesh1012/machinelearning ? reverse-engineered prompt

Build me a clean machine learning project collection in Python that matches this repository idea. I want a set of separate notebook based mini projects covering things like income prediction, car price prediction, face eye and smile detection, fruit and plant disease recognition, heart failure prediction, sentiment analysis, stock prediction, weather analysis, music genre classification, object detection, finance analysis, and a simple grade calculator plus grocery analysis.

Keep each project in its own folder with clear code, a short explanation, and a notebook that actually runs with sample data or a small demo flow. For the image based projects, use common computer vision tools and make sure the notebooks show training or inference steps clearly. For the tabular and text projects, include the usual data cleaning, model training, evaluation, and a simple prediction example. Add a README that explains what each project does and how to run it locally. If you need to check current package docs or best practices, look them up online first.
