Diversity entropy
WebSep 15, 2024 · Shannon Diversity. Claude Shannon developed his metric of entropy to use in information theory [4]. Today, it is used in many fields, such as measuring diversity in the microbiome. The best way to understand how Shannon entropy/diversity works is to look at a plot of how it works with only two species and log base 2. Webpromote species diversity. Within the robotics community, hierarchic social entropy was proposed in [23] to describe robot diversity for a multi-robot system. Like Rao’s …
