Model Evaluation Metrics and validation of the model for Machine Learning Everyone should know

Evaluating the Model is considered a core part of building an effective machine learning model. Evaluating the model allows us to ask important questions like

1. How well is my model doing? Is it a useful model?
2. Will training my model on more data improve its performance?
3. Do I need to include more features?

Evaluation metrics explain the performance of a model. An important aspect of evaluation…
