ANN not giving quite favorable results with the new dataset

1 view (last 30 days)
The performance of the Artificial Neural Network (ANN) seems promising based on the training,validation and test data, but it's not giving quite favorable results with the new dataset. Any insights into why this might be happening?

@Sunita, can you provide the datasets and show how you selected the values for the hyperparameters used in the ANN training process?

This could easily be sampling error. Even if your theoretical classification accuracy is 90%, your empirical classification accuracy (on just 20 observations?) can have a wide range.
