Universal Approximation
The ability of neural networks to approximate any continuous function. Similar to having an artist who can reproduce any image with enough detail and practice.
Unsupervised Learning
Unsupervised learning is a learning approach where models find patterns in data without labeled examples. Picture a system discovering natural groupings in data, like sorting colored balls without being told which colors exist.
Upsampling
A technique for increasing the resolution or dimension of data. Like converting a low-resolution image into a higher-resolution version while preserving details.
User Embedding
A numerical representation of user characteristics and behaviors. Imagine converting everything known about a user’s preferences into a compact digital fingerprint.
