How to know if ANN is giving good results?

The ANN's R value appears satisfactory, yet the performance curve doesn't seem favorable. Can someone clarify what this indicates? Any assistance would be appreciated.

A good R2 score but the model not performing well on testing data may be an indicator of overfitting. You can try the below mentioned steps to improve the model performance.

• Train the model on more features/predictors.
• Data augmentation to generate more training data.
• Regularization.

You can refer to the link below to understand more about regularization:
