DEEP LEARNING SUMMIT ASIA 2016
- 1. 1 How Deep Learning and Drones Can Save the World from Asteroids? @SravanthiSinha
- 2. Are asteroids a threat to the Earth? @SravanthiSinha
- 4. 4 What’s an Asteroid? Credit: NASA, JAXA and ESA (montage by Emily Lakdawalla)
- 6. Where do they live?
- 7. 7 What's the solution and why find meteorites? @SravanthiSinha
- 8. 8 Composition affects threat assessment and deflection technologies Why find meteorites? @SravanthiSinha
- 9. - It takes 100 man hours to find one meteorite - To increase meteorite finds, the efficiency must be increased - We have trajectories, but finding meteorites is difficult 9 Current approach to find meteorites @SravanthiSinha
- 10. Use a drone combined with Deep learning to increase fresh meteorite finds 10 @SravanthiSinha
- 11. 11 Why Deep Learning is the best solution? @SravanthiSinha
- 12. 12 Traditional Computer Vision - Anomaly Detection @SravanthiSinha
- 14. 14 2 wrong classifications out of 17000 patches! Our Deep Learning Solution @SravanthiSinha
- 15. 15 2 correctly labelled meteorites… 124 incorrectly labelled patches… out of 17000 patches Our Deep Learning Solution @SravanthiSinha
- 18. 18 How we solved the problem? @SravanthiSinha
- 19. rotations 19 reflection resolution brightness saturation Our meteorite pictures 320 Internet meteorites in field 280 Internet meteorites photoshopped 35 635 images... tiny dataset ! 32 augmentations per image 21000 images... respectable dataset ! Dataset Augmentation @SravanthiSinha
- 20. 20 ~15 million natural images Leveraging Big Data @SravanthiSinha
- 21. 21 GoogLeNet AlexNet ~6 million parameters ~61 million parameters Leveraging Pre-trained Networks @SravanthiSinha
- 23. 23 Hardware / Software Each model ~2 hours to train On a CPU it would be ~1 week ! @SravanthiSinha

- How to deflect an Asteroid?
- Out of 800 trajectories, we only have 27 recovered meteorites . We need to increase that > 40 meteorite types > 100 asteroid families Within each family, there’s a range of properties Can Deep learning improve our ability to locate freshly fallen meteorites?
