WebbCluster bus is a node-to-node communication channel that uses a binary protocol, which is more suited to exchanging information between nodes due to little bandwidth and processing time. Nodes use the cluster bus for failure detection, configuration updates, failover authorization, and so forth. WebbFor a ROC curve to work, you need some threshold or hyperparameter. The numeric output of Bayes classifiers tends to be too unreliable (while the binary decision is usually OK), and there is no obvious hyperparameter.
