Build working machine-learning models without the heavy mathematics.
Applied ML Fundamentals is a hands-on introduction to machine learning for people who want to build working models without wading through dense mathematics. You will learn how the main families of algorithms actually behave, when to reach for each, and how to train, evaluate and improve a model in Python with scikit-learn. The emphasis is judgement and practice: real datasets, honest evaluation metrics, and the habits that avoid pitfalls like overfitting and data leakage. You finish able to take a raw dataset and ship a defensible predictive model. A verified e-Certificate of competency and e-Marksheet from the Deep Science & Technology Consortium.
Applied ML Fundamentals teaches you to build, evaluate and improve real machine-learning models using Python and scikit-learn, with intuition and practice in place of dense theory.
1. Understand how regression, tree-based and clustering algorithms work in plain terms.
2. Clean, split and prepare real datasets for reliable training.
3. Train and tune models with scikit-learn without heavy mathematics.
4. Choose the right evaluation metric and diagnose overfitting and leakage.
5. Package a model into a simple, reproducible workflow.
