## Interstellar Classifier
|
| 12 |
+
|
| 13 |
+
Classify images of interstellar objects such as galaxies, nebulae, comets, asteroids, quasars, and star clusters.
|
| 14 |
+
|
| 15 |
+
Built for the fast.ai [Practical Deep Learning Course](https://course.fast.ai/) by:
|
| 16 |
+
- creating a custom dataset (less than 150 images per label) using [Bing search API](https://www.microsoft.com/en-us/bing/apis/bing-web-search-api);
|
| 17 |
+
- augmenting the dataset; and,
|
| 18 |
+
- fine tuning ResNet50 (1 + 3 epochs) in [paperspace.com](https://www.paperspace.com/).
