Co to jest Digital Fenotyping?

Digital phenotyping refers to continuours, passive collection of data from smartphones, wearables, and texr connectis to quantify an individual 's behavour, cognition, and moud. The concept was formalized by psychiatrist dr John Torous and collegagues, who defined it as conditional quention; the momento quantification of thee individulatioult -leveready ham phenotype in situ using data frem personas.

Te power of digital phenotyping lies in it s ability to capture data in naturalistic settings, without ot requiring thee e user to actively report providents. This reduces recall bias and provides a high-resolution, difficinal pictury of daily life.
