In this project you will implement a Convolutional Neural Network (CNN) in two different ways:

  • a step by step approach using Numpy, and
  • using Tensorflow framework to perform classification of Cifar10 dataset.

The goal of this assignment is to help you understand CNN’s by building their different components. You will be applying your Tensorflow CNN implementation on the CIFAR10 dataset classification. In both approaches some of the components include, forward convolution, backward convolution, zero padding, max-pooling and average-pooling. Backpropagation code is provided for you.

In order to help you implement this you are provided with starter code that contains two Jupyter notebooks and images necessary for this project. The files cnn-with-backprop.ipynb and Cifar10ClassificationUsingCNN.ipynb are to be used for the step by step approach and the Tensorflow framework approach, respectively. The descriptions of these files are as follows:

  • cnn-with-backprop.ipynb - backpropagation algorithm is implemented in this file. Start with this file.
  • Cifar10ClassificationUsingCNN.ipynb is to be used for our second approach using Tensorflow framework.

A detailed description of these files is being skipped here because an elaborate documentation has been included in each one of these files. The comments in the files are self explanatory and include locations where you are required to fill in your code. In addtion, you may refer to the Artificial Neural Networks and Convolutional Neural Networks lectures covered in class.

What to Implement

Most of the implementation details are provided to you in the Jupyter notebooks. You would be required to write code in these files identified by the comments in them.

Submission Guidelines

You are required to submit the following files:

  • cnn-with-backprop.ipynb for the step by step approach to build a Convolutional Neural Network. (40 points)
  • Cifar10ClassificationUsingCNN.ipynb for the Tensorflow framework approach to classify CIFAR10 data . (40 points)
  • Report should contain a detailed description of the answers to the questions inside the second Jupyter notebook as a markdown. Some of those questions are included in the Jupyter notebook (20 points)

Collaboration Policy

You may discuss methods and ideas with your peers but may not share code.
