Artificial intelligence helps track sharks in the ocean

Turn AI cameras on your employees and you can measure their productivity. Fly them over the Pacific Ocean and you've got yourself an automated shark-warning system.

What's happening: UC Santa Barbara, with the help of a few AI experts from Salesforce, is using drones to monitor sharks near California beaches in real time.

Training real AI with fake data

AI systems have an endless appetite for data. For an autonomous car's camera to identify pedestrians every time — not just nearly every time — its software needs to have studied countless examples of people standing, walking and running near roads.

Yes, but: Gathering and labeling those images is expensive and time consuming, and in some cases impossible. (Imagine staging a huge car crash.) So companies are teaching AI systems with fake photos and videos, sometimes also generated by AI, that stand in for the real thing.
