Hi,
I'm following your guide Neural Networks to Production, From an Engineer but I have problems accessing the site, it gives me a Database Error ( Error establishing a database connection ).

Hello,

Thank you for this awesome repo, giving me better understanding of different approach in text classification.
Please, is it possible to have access to the code used for the hyperparameter tuning?

Thank you.

Hi,
I was trying to test on pre-trained model(cnn). I successfully loaded your model with following commands :

  # load json and create model
   json_file = open(model_name + '.json', 'r')
   loaded_model_json = json_file.read()
   json_file.close()
   model = model_from_json(loaded_model_json)

Now, when I tried to test it through following code:

test_comments, test_comments_category = get_custom_test_comments()

x_test, _, y_test, _ = encode_data(test_comments, test_comments_category,
                                   data_split=1.0,
                                   embedding_name=embedding_name,
                                   add_pos_tags_flag=pos_tags_flag)

x_test = sequence.pad_sequences(x_test, maxlen=maxlen)
y_test = keras.utils.to_categorical(y_test, num_classes)

score = model.evaluate(x_test, y_test,
                       batch_size=batch_size, verbose=1)

^this last line of model.evaluate resulted in error :

InvalidArgumentError: indices[13,490] = 22271 is not in [0, 15000)
	 [[Node: embedding_1_9/embedding_lookup = GatherV2[Taxis=DT_INT32, Tindices=DT_INT32, Tparams=DT_FLOAT, _class=["loc:@dropout_1_9/cond/Switch_1"], _device="/job:localhost/replica:0/task:0/device:CPU:0"](embedding_1_9/embeddings/read, embedding_1_9/Cast, embedding_1_9/embedding_lookup/axis)]]

which I figured out that it might be because of word id which is contained in x_test, because value of max_words which we have is 15000 and maximum value in x_test is far greater than 15000 so it's not able to find words which have id greater than 15000. I tried to divide all the values of x_test by 100 and then converted all the values to integer. Then it successfully worked.

So , can you please suggest me If I am doing anything wrong, or any other word encoding needs to be loaded?
Thanks for the help.

Hey there, Is it possible to get the final dataset with splits? I intend to train a transformer model for classifying questions vs statements. I can later create a pull request and that model can integrated to this wonderful repo of classifiers that you already have. Thanks!

Hi, I want to use the pre-trained model to classify my sentences. But I am not that familiar with Deep Learning.
Here I have some questions:

1. is tensorflow==2.4.0 necessary?
2. I have some sentences stored as txt. files, can I use them as inputs? If not, what should be the input while using the pre-trained model?

While using default word_encoding if a word is not present in dictionary key it is given an encoding 0. I saw your default_word_encoding.json and found multiple words have value 0 and so on. If it is intended can I know how model differentiates between new words and seen words with same encoded value?

The values being printed by gen_test_comments are

-------------------------
command 1672
statement 80993
question 131219
-------------------------

However, the actual values are 1111, 80167 and, 131001 for commands, statements and questions respectively. The values stored in the variables like command_count include duplicate sentences.
While the tagged_comments dict takes care of duplicate values, the counts still contain duplicates.
