Why Learn Machine Learning Engineer?
Design, train, evaluate and serve practical machine-learning models.
This learning path is especially useful for students who want practical exposure, portfolio-ready work and a stronger understanding of how concepts are applied in real situations. At Madras Academy, we always recommend learning through guided practice rather than passive reading alone.
Prerequisites
- Basic computer and internet usage.
- A willingness to practise regularly during the 16 weeks learning period.
- Notebook for documenting commands, code, ideas and troubleshooting steps.
- Some prior familiarity with programming, operating systems or web basics will help.
Tools & Technologies Commonly Used
- Python
- Scikit-learn
- XGBoost
- ML Pipelines
- FastAPI
