Clojure expresses entropy and relative-entropy exactly as the math and runs it on 1,000,000 random numbers to compare implementations: naive map/reduce ~50 ms, Java-array approach ~25 ms and 8 milliseconds with reducers via fork-join. Integrations shown: Datomic queries computing relative entropy across server response-time distributions to flag a bimodal/anomalous server, Cascalog/Hadoop and JBlas bridges to Mahout/Weka, and a production example of 130,000 lines, €13M funding powering robot recycling.
