What does "Unimodal" mean?

Table of Contents

Unimodal refers to a method or approach that focuses on a single type of data or information. In many cases, it deals with only one source, such as text, audio, or video. For example, a unimodal system might analyze only spoken words without considering visual elements like body language or facial expressions.

In tasks like emotion recognition or video analysis, unimodal techniques look at one aspect at a time. While this can be simpler, it may miss important context that comes from combining different types of data. By looking at just one mode, these methods can be less effective in understanding complex situations where multiple forms of information are present.
