Generating Text Using TensorFlow

One fun thing we can do with machine learning is generating text! We can build a model that will predict the next word in a sequence. This combines interesting aspects of both sequence processing and natural language processing. This lab will give you more practice in both of these important areas of machine learning. ### Prerequisites This lab is designed to be completed in PyCharm running on your machine. You should have PyCharm and TensorFlow installed before attempting this lab. We will not be covering this setup in the lab.

Challenge

Retrieve and Load the Tiny Frankenstein Data
1. Download the Tiny Frankenstein dataset: https://storage.googleapis.com/acg-datasets/tiny_frankenstein.tgz.
2. Load the raw text into the program.
3. Convert the text to lowercase.
Challenge

Turn the Text Data into Token Sequences
1. Train a tokenizer on the Frankenstein text using every available word.
2. Find the total number of learned words.
3. Convert the Frankenstein text to tokens.
4. Convert the tokens to sequences.
Challenge

Build a Model to Predict Tokens
1. Create a recurrent neural network to learn the token sequences.
  - Hint: Bidirectional LSTMs work really well for this task!
2. Compile the model with an appropriate loss function and optimizer.
  - Hint: You might want to increase the learning rate of the optimizer. This model can take a very long time to converge with the default learning rate.
3. Train your model for 10-20 epochs.
Challenge

Generate Text!
1. Create a reverse token lookup dictionary from the tokenizer's word_index.
2. Create tokenized text to start the predictions.
3. Use the model to predict the next token.
4. Append the predicted token to the text, truncating earlier values.
5. Continue using the model to predict as many tokens as you'd like!
