14: Building a Character-Based Text Classifier

Ever wonder how to automatically detect language from a script? How does Google do it? 

Ever wonder how Amazon knows whether you are searching for a product or a SKU on its search bar? 

We look into character-based text classifiers in this episode. We cover 2 types of models. First is the bag-of-words models such as Naive Bayes, logistic regression and vanilla neural network. Second we cover sequence models such as LSTMs and how to prepare your characters for the LSTMs including things like one-hot encoding, padding, creating character embeddings and then feeding these into LSTMs. We also cover how to set up and compile these sequence models.
