"What's New? Interpretable Discovery in Large Image Data Sets"
Automated detection of new, interesting, unusual, or anomalous items in large image data sets could help detect new near-Earth asteroids, fresh impact craters on Mars, and other key phenomena that might otherwise be lost within a large archive. Many image data analysis systems are turning to convolutional neural networks (CNN) to represent image content due to their success in achieving high classification accuracy rates. However, CNN representations are notoriously difficult for humans to interpret. In this talk, I will discuss a strategy that combines novelty detection with CNN image features and yields interpretable explanations of novel image content. I will show examples of discovery in Mars rover and Earth ecology image data sets.
