Key Takeaways

The key takeaways from this section include:

  • A Sequence Model is a general term for a special class of Deep Neural Networks that work with a time series of data as an input
  • In the deep learning context, sequence models are also referred to as "Recurrent Neural Networks" (RNNs)
  • Sequence Models are often used for text classification, sequence generation, etc.
  • A basic Recurrent Neural Network is a neural network that passes it's output from a given example back into itself as input for the next example (which feels a little bit like the time series models we've seen)
  • RNN architectures use a special type of backpropagation referred to as "backpropagation through time"
  • To special types of RNNs are referred to as "Long Short Term Memory" (LSTM) and "Gated Recurrent Unit" (GRU) models.
