Week 4: Handling Complex Images - Happy or Sad Dataset In this assignment you will be using the happy or sad dataset, which contains 80 images of emoji-like faces, 40 happy and 40 sad. Create a convolutional neural network that trains to 99.9% accuracy on these images, which cancels training upon hitting this training accuracy threshold. import matplotlib.pyplot as plt import tensorflow as tf im..

Week 3: Improve MNIST with Convolutions In the videos you looked at how you would improve Fashion MNIST using Convolutions. For this exercise see if you can improve MNIST to 99.5% accuracy or more by adding only a single convolutional layer and a single MaxPooling 2D layer to the model from the assignment of the previous week. You should stop training once the accuracy goes above this amount. It..

Week 2: Implementing Callbacks in TensorFlow using the MNIST Dataset In the course you learned how to do classification using Fashion MNIST, a data set containing items of clothing. There's another, similar dataset called MNIST which has items of handwriting -- the digits 0 through 9. Write an MNIST classifier that trains to 99% accuracy and stops once this threshold is achieved. In the lecture ..

Week 1 Assignment: Housing Prices In this exercise you'll try to build a neural network that predicts the price of a house according to a simple formula. Imagine that house pricing is as easy as: A house has a base cost of 50k, and every additional bedroom adds a cost of 50k. This will make a 1 bedroom house cost 100k, a 2 bedroom house cost 150k etc. How would you create a neural network that l..
