Fun Fact

Neural network training: Some early facial recognition models struggled with diverse skin tones because their training datasets lacked global representation.

Glossary

neural network (noun)
A computer system modeled on the human brain, designed to recognize patterns and translate raw data into mathematical representations. Apple deployed this technology in 2017 to process facial scans locally on the iPhone X.
