The [wiki page](https://en.wikipedia.org/wiki/Count%E2%80%93min_sketch) for CMS describes a variant with a different query function called count-mean-min-sketch; this tries to reduce bias in the estim…

We can reduce the size our the CMS to 1/4 if we use the logic behind https://github.com/seiflotfy/count-min-log

When adding two CountMinSketch objects, is it intentional that the heavy hitters are duplicated when they're summed using the monoid? The `heavyHitters` method on CMS is correct because it filters out…

The width of the sketch [according to the paper](http://www.cse.unsw.edu.au/~cs9314/07s1/lectures/Lin_CS9314_References/cm-latin.pdf) should be set to `ceil(e/epsilon)` where e is Euler's number. How…

Wrap the low-level implementations (min count sketch, hash tables for key iteration...) in a Counter interface. The goal is to make Counter Bounter switch trivial for users.
Methods that cannot be…

Aside from being reusable and useful on its own, it is specifically going to be useful for some upcoming algorithms, such as count-min sketch-based sparse approx nearest neighbors and for the approxim…

## Motivation
Currently, we have a limit of N=128 block ranges (or 1028 blocks after #2493) with LRU eviction. This is OK, but we could evict many pages at once, resulting in a relatively high over…
