Primes¶
- Metric
- The abstraction also makes the divergence boundary a first-class object of reasoning — recognizing that Kullback–Leibler divergence is not a metric (it violates symmetry and the triangle inequality) is exactly the kind of structural news the framing surfaces, and it changes which tools may be used.
This sourceDefines the KL divergence, which is non-symmetric and violates the triangle inequality — hence a divergence, not a metric.
