Exercise 4
Start course
1h 45m

Learn about the importance of gradient descent and backpropagation, under the umbrella of Data and Machine Learning, from Cloud Academy.

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.

Learning Objective

  • Understand the importance of gradient descent and backpropagation
  • Be able to build your own neural network by the end of the course




Hey guys welcome back. This video is about Exercise four in section four. This exercise is about Tensorflow playground. Tensorflow playground is a very nice web application from the guys at Tensorflow that provides an interactive environment where you can play with simple fully connected neural nets on very simple data sets. These are two featured data sets where you have to separate groups of points that are blue and orange. So play with it a few minutes. There's no real goal. You don't need to understand the meaning of every knob and button but just to develop a feeling, an intuition about how things work. So there's no real challenge here just feel free to explore, play with it and see what you find. Good luck and see you in the next video.
