Although it is often intuited as a distance metric, the KL divergence is not a true metric, as the Kullback-Leibler divergence is not symmetric, nor does it satisfy the triangle inequality.
The divergence of a vector field measures the rate at which the field "spreads out" from a given point. Physically, it indicates whether there is a net source (positive divergence) or sink (negative divergence) of the field at that point. For example, in fluid dynamics, a positive divergence in a velocity field suggests fluid is originating from that point, while negative divergence implies fluid is converging towards it. Thus, divergence provides insight into the behavior of a field in terms of local expansion or contraction.
Divergence is a vector operator that measures the magnitude of a vector fields source or sink at a given point.

KLD stands for Kullback-Leibler Divergence. It is a measure of how one probability distribution diverges from a second, expected probability distribution. KLD is a unitless quantity.
KL (Kullback-Leibler) divergence and KLD (Kullback-Leibler divergence) refer to the same concept in information theory, where KL is often used as a shorthand notation. It measures the difference between two probability distributions, typically a true distribution and an approximate distribution, quantifying how much information is lost when the approximate distribution is used to represent the true one. There is no inherent difference between KL and KLD; they are interchangeable terms used in the context of statistical analysis and machine learning.
In mathematics, KL often refers to the Kullback-Leibler divergence, a measure of how one probability distribution diverges from a second, expected probability distribution. It quantifies the information lost when approximating one distribution with another. KL divergence is commonly used in statistics, machine learning, and information theory to assess model performance and data distributions.
