This tutorial introduces the programming language Julia and the Knet deep learning framework. By the end, the reader should be able to define, train, evaluate, and visualize basic MLP, CNN, and RNN models. Each notebook is written to work stand-alone but they rely on concepts introduced in earlier notebooks, so I recommend reading them in order. Every Knet function outside of the standard Julia library is defined or explained before use.

To run the notebooks on a Jupyter server, start julia in this directory then install and run IJulia by typing the following at the julia> prompt: (see IJulia.jl for more information).

julia> using Pkg
julia> Pkg.add("IJulia")
julia> using IJulia
julia> notebook()

These notebooks are also available in Google Drive which should let you run them on Google Colab provided you add Julia support first using the colab_install_julia notebook.
