Kayak uses algorithms to tag photos of hotels, determining whether they’re showing a beach, bedroom, bathroom, or gym, for example. But the tagging process isn’t perfect.

While AI is pretty good at determining whether a picture is showing a dog or a cat, it’s not as accurate when it comes to other areas, like image classification. Even if your AI achieves 95% accuracy, 50 out of 1,000 predictions will still end up being wrong.
