# A Convolution Neural Network (CNN) From Scratch

This was written for my 2-part blog post series on CNNs:

- [CNNs, Part 1: An Introduction to Convolution Neural Networks](https://victorzhou.com/blog/intro-to-cnns-part-1/)

- [CNNs, Part 2: Training a Convolutional Neural Network](https://victorzhou.com/blog/intro-to-cnns-part-2/)

To see the code (forward-phase only) referenced in Part 1, visit the [forward-only](https://github.com/vzhou842/cnn-from-scratch/tree/forward-only) branch.

## Usage

Install dependencies:

```bash

$ pip install -r requirements.txt

```

Then, run it with no arguments:

```bash

$ python cnn.py

$ python cnn_keras.py

```

You can also [run this code in your browser](https://repl.it/@vzhou842/A-CNN-from-scratch-Part-2).
