Why emotion recognition AI can't reveal how we feel

The growing use of emotion recognition AI is causing alarm among ethicists. They warn that the tech is prone to racial biases, doesn't account for cultural differences, and is used for mass surveillance. Some argue that AI isn't even capable of accurately detecting emotions. A new study published in Nature Communications has shone further light on these shortcomings. The researchers analyzed photos of actors to examine whether facial movements reliably express emotional states.
