Improving Model Accuracy
Obtaining a ML model that matches your needs usually involves iterating through this ML process and trying out a few variations. You might not get a very predictive model in the first iteration, or you might want to improve your model to get even better predictions. To improve performance, you could iterate through these steps:
-
Collect data: Increase the number of training examples
-
Feature processing: Add more variables and better feature processing
-
Model parameter tuning: Consider alternate values for the training parameters used by your learning algorithm
