Reducing false positives in credit card fraud detection ...

Using machine learning to detect financial fraud dates back to the early 1990s and has advanced over the years. Researchers train models to extract behavioral patterns from past transactions, called “features,” that signal fraud. When you swipe your card, the card pings the model and, if the features match fraud behavior, the sale gets blocked.

cobalt processing | Uses, Supply, & Facts | Britannica

Cobalt processing, preparation of the metal for use in various products.. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure.At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally.
