Helper Classes
These classes are required for certain sketches or specific functionality within sketches. Some of them are abstract base classes, but in those cases there is at least one reference example of a concrete class.
serdeis used when serializing and deserializing sketches.
jaccardis used to compute the Jaccard similarity between pairs of theta or tuple sketches.
tuple_policyis required to use atuple_sketchby specifying how summaries are combined.
ks_test()performs a Kolmogorov-Smirnov test on absolute-error quantiles family sketches.
kernel_functionis required when using akernel_sketchfor Kernel Density Estimation.
