How do I know if my machine learning model has good performance?

Various ways to evaluate a machine learning model’s performance

  • Confusion matrix.
  • Accuracy.
  • Precision.
  • Recall.
  • Specificity.
  • F1 score.
  • Precision-Recall or PR curve.
  • ROC (Receiver Operating Characteristics) curve.

How can you improve the accuracy of the deep learning model?

Here is the checklist to improve performance:

  1. Analyze errors (bad predictions) in the validation dataset.
  2. Monitor the activations.
  3. Monitor the percentage of dead nodes.
  4. Apply gradient clipping (in particular NLP) to control exploding gradients.
  5. Shuffle dataset (manually or programmatically).

How much accuracy is good your machine learning model?

If you are working on a classification problem, the best score is 100% accuracy. If you are working on a regression problem, the best score is 0.0 error. These scores are an impossible to achieve upper/lower bound. All predictive modeling problems have prediction error.

Can machine learning models be continuously trained?

Continual learning is the ability of a model to learn continually from a stream of data.
