6 Tips for Building a Robust Machine Learning Model

1. Understand the problem thoroughly before jumping into the model.
➝ Taking time to understand the problem helps build a solution aligned with business needs and goals.

2. Focus on feature engineering to improve accuracy.
➝ Well-engineered features make a big difference in model performance. Collaborating with data engineers on clean and well-structured data can simplify feature engineering.

3. Start simple, test assumptions, and iterate.
➝ Begin with straightforward models to test ideas quickly. Iteration and experimentation will lead to stronger results.

4. Keep track of versions for reproducibility. 
➝  Documenting versions of data and code helps maintain consistency, making it easier to reproduce results.

5. Regularly validate your model with new data.
➝ Models should be updated and validated as new data becomes available to avoid performance degradation.

6. Always prioritize interpretability alongside accuracy.
➝ Building interpretable models helps stakeholders understand and trust your results, making insights more actionable.
