A type of machine learning based on multi-layered artificial neural networks that mimic the information processing processes of the human brain. It is used in a wide range of applications, such as machine translation, speech recognition, and intelligent robotics. From a psychological perspective, deep learning helps improve people’s personal experiences, for example, by improving targeted recommendations or personalizing content. However, there may be concerns about the degree of control over these systems and the unintended consequences that can arise when using deep learning.
