CountMinSketch In Python

Thanks to my friend Chris I've been pondering some of the work from Misha Bilenko at Microsoft. This lead me down the path of investigating the CountMinSketch algorithm for tracking counts of entities in a stream. To help me learn I wrote a Python implementation of CountMinSketch.

You can use it like so

from countminsketch.countminsketch import CountMinSketch
d = 10
w = 100
cms = CountMinSketch(d=10, w=100)
cms.add('test_value')
print("Count of elements is:")
print(cms.query('test_value'))
