❓ Frequently Asked Questions
What is a machine learning workflow?
A sequence of steps for building ML models from problem definition to deployment, typically including data collection, preprocessing, feature engineering, model selection, training, evaluation, and deployment.
What happens during data collection and preprocessing?
Data collection gathers raw data from sources; preprocessing cleans and formats it (e.g., handling missing values, normalization) to make it ready for modeling.
What is feature engineering, and why is it important?
Creating and selecting informative features from raw data to improve model performance; examples include scaling, encoding, and deriving new features.
What is model selection, training, and evaluation?
Model selection chooses the algorithm; training fits the model to data; evaluation assesses performance on held-out data to judge generalization.
What is deployment in ML?
Deploying means putting the trained model into a production environment where it makes predictions on new data, with monitoring and maintenance.
