Deep Learning playground

This repository compiles different challenges for deep learning enthusiasts. It was initially dedicated to Udacity scholars from the Deep Learning nanodegree.

Diving further into the different topics of the course and notebook exercises from the nanodegree repo, you can find the following exercises for each lesson.

Neural Network building blocks

Create the building blocks for your own MLP in numpy by completing two challenges:

Feed-forward MLP (notebook)
Full MLP back-propagation (notebook)

Convolutional neural networks

Implementing convolutional layers as part of your layer portfolio with numpy by completing two challenges:

Convolutional layers (being finalized)
Layer activation visualization (coming soon)

Next upcoming challenges

Optimizers
Regularization
Style Transfer
Recurrent Neural Networks
Generative Adversarial Networks
Deep Reinforcement Learning

Requirements

The numpy and matplotlib packages are required to properly use the repo.
Tested on the following version:

import sys
import numpy, matplotlib
print('Python %s' % '.'.join(map(str, sys.version_info[:3])))
print(f'Numpy {numpy.__version__}, Matplotlib {matplotlib.__version__}')

Python 3.6.5
Numpy 1.15.4, Matplotlib 2.2.3

How to use it

Each lesson has a folder with a folders and other modules. The notebook will contain all the instructions.
Fork this repo to complete the exercises, and please notify the author of potential bugs/issues

Completing an exercise

Run your jupyter notebook server in the same environment you installed the previously mentioned requirements.
If you are using Anaconda distribution, open your terminal (Linux/MacOS) or Anaconda prompt (Windows) and run:

jupyter notebook

Now navigate to the corresponding folder and follow the instructions of the notebook.

Submitting a request / Reporting an issue

If you wish to submit a request or report an issue, go to the Issues section, and create a "New issue".

Regarding issues, use the following format for the title:

[Lesson #] Your Issue name

Example: [Lesson 2] Adding more instructions for the layer exercise
and these guidelines for the comment:

Ensure you already have restart your kernel before reporting an issue
Specify your setup (OS, OS version, Python version, requirements' versions)
Format and specify the part of the code that is an issue
Format and specify the error/issue that you encounter
If relevant, explain what you have already tried to resolve the issue

Regarding requests, use the following title format:

[Request] Your request name

Example: [Request] Creating an exercise illustrating dropout
