Introduction to Neural Networks Lab

led by Prof. Hyungsuk Tak

Astroinformatics Summer School 2022

Organized by Penn State Center for Astrostatistics

This repository contains one computational notebook:

  • neuralnetwork_intro.jl (Pluto notebook): Provides an introduction to neural networks using classification of high-redshift quasars as an example

The lab does not assume familiarity with Julia. While it can be useful to "read" selected portions of the code, the lab tutorials aim to emphasize understanding how algorithms work, while minimizing need to pay attention to a language's syntax.

Running Labs

Instructions will be provided for students to run labs on AWS severs during the summer school.
Others may install Julia and Pluto on their local computer with the following steps:

  1. Download and install current version of Julia from julialang.org.
  2. Run julia
  3. From the Julia REPL (command line), type
julia> using Pkg
julia> Pkg.add("Pluto")

(Steps 1 & 3 only need to be done once per computer.)

  1. Start Pluto
julia> using Pluto
julia> Pluto.run()
  1. Open the Pluto notebook for your lab
