Use inverse transform with deep learning Conceptual clarity needed

0 votes

I have built a deep learning model that encoded the value using LabelEncoder() which is further being converted to categorical values using np_utils.to_categorical()

labels = np.array(labels)
transformed_features = docs_encoded.astype(int)
encoder = LabelEncoder()
encoded_labels = encoder.transform(labels)
transformed_labels = np_utils.to_categorical(encoded_labels)

Predicting gives me results like : array([[2.40659632e-04, 3.97350988e-04, 4.11552377e-04, ...,

Doing np.argmax(to_categorical(encoder.inverse_transform(encoded_value))) rasies a ValueError: invalid literal for int() with base 10: 'coldstorage'. I know it just means that the argument might be something other than a digit/number. Can't figure this one out. Need help with converting the numbers back to user_ids. Thanks.

My data looks like:
user_id     date                body

Hey @Anan,

Can you please provide the code you have written for this? Or if you have used 'int' anywhere in your code, just use 'float' instead of that. I hope your error will go off.
