ML sequence model to automatically add emoji to your sentence! ---------- focus: LSTM

Emojify!

Have you ever wanted to make your text messages more expressive? Your emojifier app will help you do that. So rather than writing:

"Congratulations on the promotion! Let's get coffee and talk. Love you!"

The emojifier can automatically turn this into:

"Congratulations on the promotion! 👍 Let's get coffee and talk. ☕️ Love you! ❤️"

• You will implement a model which inputs a sentence (such as "Let's go see the baseball game tonight!") and finds the most appropriate emoji to be used with this sentence (⚾️).

Using word vectors to improve emoji lookups

• In many emoji interfaces, you need to remember that ❤️ is the "heart" symbol rather than the "love" symbol.
  • In other words, you'll have to remember to type "heart" to find the desired emoji, and typing "love" won't bring up that symbol.
• We can make a more flexible emoji interface by using word vectors!
• When using word vectors, you'll see that even if your training set explicitly relates only a few words to a particular emoji, your algorithm will be able to generalize and associate additional words in the test set to the same emoji.
  • This works even if those additional words don't even appear in the training set.
  • This allows you to build an accurate classifier mapping from sentences to emojis, even using a small training set.

The above notebook cantains two models to accomplish this

1. Baseline Model: Which just uses the average of all word vectors in a sentence and pushes it through a softmax classifier
2. 2 layer deep LSTM
