Exercise 1
Start course

From the internals of a neural net to solving problems with neural networks to understanding how they work internally, this course expertly covers the essentials needed to succeed in machine learning.

This course moves on from cloud computing power and covers Recurrent Neural Networks. Learn how to use recurrent neural networks to train more complex models.

Understand how models are built to allow us to treat data that comes in sequences. Examples of this could include unstructured text, music, and even movies.

This course is comprised of 9 lectures with 2 accompanying exercises.

Learning Objective

  • Understand how recurrent neural network models are built
  • Learn the various applications of recurrent neural networks




Hey guys, welcome back. In this video, we'll review Exercise 1, of Section 8. Where we ask you to perform a reshaping of the inputs in the windowed time-series prediction that we've done in class. Essentially, what we want to do, is pass to the LSTM, the 12 months, as a sequence of single months. Basically what we did in class, was to take the 12 months, and pass them as a vector with 12 coordinates, so, we passed the months in parallel and so we really didn't exploit the LSTM memory, we just passed the whole vector at once. What we're gonna do here, is pass the months one at a time, it's actually pretty simple, you'll have to reshape, x_train and x_test so that they represent a set of sequences instead of a set of vectors. And retrain the same LSTMmodel, adapting the input_shape. Compare the performance with the previous model and tell us if it's better or worse. Thank you for watching, and good luck.
