Bonus assignments

Things to do after you finish the tutorial

• Tweak the parameters of the neural network model. For example, change the number of hidden nodes.
• Try to add dropout to the input layer, and tweak the rate parameter
• Try to disregard all tags that occur only once in the dataset. This will result in a smaller input vector.
• Play around with simple neural network architectures here: https://playground.tensorflow.org/
• Include information from topics and relevant_topics in the input vector. You can use the same technique as you used for tags.
• Include information from title in the input vector. Here is an example of how you can deal with this:
  • Split the title into words
  • Remove punctuation, whitespace and perhaps numbers
  • Perhaps remove words that appear only once in the dataset?
  • Apply TF-IDF (look this up on the internet)
