ml-class

Projects

These are specific bite-sized projects to learn an aspect of deep learning, starting from scratch. There is an associated video around 10 minutes long. I assume no background in ML but some proficiency in python. The projects are in order from beginner to more advanced, but feel free to skip around.

Getting Started

1. Clone this repository
2. Get the python libraries (run ‘pip install -r requirements.txt’)

You don’t need a fancy computer to run most of the examples, but especially to do the later projects you may want to invest in a GPU.

Examples

In my in-person classes, I typically use a lot of the examples in the directory examples. This code is liable to change as I update things.

Reusing the materials

Please feel free to use these materials for your own classes/projects etc. If you do that, I would love it if you sent me a message and let me know what you’re up to.

Windows

Git

Install git if you don’t have it: https://git-scm.com/download/win

Anaconda

Install anaconda

Try running the following from the command prompt:

python --version

You should see something like

Python 3.6.1 :: Anaconda 4.4.0 (64-bit)

If don’t see “Anaconda” in the output, search for “anaconda prompt” from the start menu and enter your command prompt this way. It’s also best to use a virtual environment to keep your packages silo’ed. Do so with:

conda create -n ml-class python=3.6
activate ml-class

Whenever you start a new terminal, you will need to call activate ml-class.

Clone this github repository

git clone https://github.com/lukas/ml-class.git
cd ml-class

libraries

pip install wandb
conda install -c conda-forge scikit-learn
conda install -c conda-forge tensorflow
conda install -c conda-forge keras

Linux and Mac OS X

Install python

You can download python from https://www.python.org/downloads/. There are more detailed instructions for windows installation at https://www.howtogeek.com/197947/how-to-install-python-on-windows/.

The material should work with python 2 or 3. On Windows, you need to install the 64 bit version of python 3.5 or 3.6 in order to install tensorflow.

Clone this github repository

git clone https://github.com/lukas/ml-class.git
cd ml-class

If you get an error message here, most likely you don’t have git installed. Go to https://www.atlassian.com/git/tutorials/install-git for instructions on installing git.

Install necessary pip libraries

pip install -r requirements.txt

Reading material for people who haven’t done a lot of programming

If you are uncomfortable opening up a terminal, I strongly recommend doing a quick tutorial before you take this class. Setting up your machine can be painful but once you’re setup you can get a ton out of the class. I recommend getting started ahead of time.

If you’re on Windows I recommend checking out http://thepythonguru.com/.

If you’re on a Mac check out http://www.macworld.co.uk/how-to/mac/coding-with-python-on-mac-3635912/

If you’re on linux, you’re probably already reasonably well setup :).

If you run into trouble, the book Learn Python the Hard Way has installation steps in great detail: https://learnpythonthehardway.org/book/ex0.html. It also has a refresher on using a terminal in the appendix.

Reading material for people who are comfortable with programming, but haven’t done a lot of python

If you are comfortable opening up a terminal but want a python intro/refresher check out https://www.learnpython.org/ for a really nice introduction to Python.

Suggestions for people who have done a lot of programming in python

A lot of people like to follow along with ipython or jupyter notebooks and I think that’s great! It makes data exploration easier. I also really appreciate pull requests to make the code clearer.

If you’ve never used pandas or numpy - they are great tools and I use them heavily in my work and for this class. I assume no knlowedge of pandas and numpy but you may want to do some learning on your own. You can get a quick overview of pandas at http://pandas.pydata.org/pandas-docs/stable/10min.html. There is a great overview of numpy at https://docs.scipy.org/doc/numpy/user/quickstart.html.
