APOGEE data exploraiton with unsupervised machine learning

This repository contains examples for using the data products from: Detecting outliers and learning complex structures with large spectroscopic surveys – a case study with APOGEE stars

The examples include:

1. Plotting the t-SNE maps that are shown in the paper, such as

2. Given an APOGEE ID, retrive objects with similar spectra

3. Calculate a weirdness score

4. Select objects from the t-SNE map

See jupyter notebook for more examples
