Astronomical Classifier

Classify images of astronomical objects such as galaxies, nebulae, comets, asteroids, quasars, and star clusters.

Built for the fast.ai Practical Deep Learning Course by:

• creating a custom dataset (less than 150 images per label) using Bing search API;
• augmenting the dataset; and,
• fine tuning ResNet50 (1 + 3 epochs) in paperspace.com.
