Documentation | External Resources | Research Paper

Shapley is a Python library for evaluating binary classifiers in a machine learning ensemble.

The library consists of various methods to compute (approximate) the Shapley value of players (models) in weighted voting games (ensemble games) - a class of transferable utility cooperative games. We covered the exact enumeration based computation and various widely know approximation methods from economics and computer science research papers. There are also functionalities to identify the heterogeneity of the player pool based on the Shapley entropy. In addition, the framework comes with a detailed documentation, an intuitive tutorial, 100% test coverage and illustrative toy examples.


Citing

If you find Shapley useful in your research please consider adding the following citation:

@misc{rozemberczki2021shapley,
      title = {{The Shapley Value of Classifiers in Ensemble Games}}, 
      author = {Benedek Rozemberczki and Rik Sarkar},

      eprint = {2101.02153},
      archivePrefix = {arXiv},
      primaryClass = {cs.LG}
}

A simple example

Shapley makes solving voting games quite easy - see the accompanying tutorial. For example, this is all it takes to solve a weighted voting game with defined on the fly with permutation sampling:

import numpy as np
from shapley import PermutationSampler

W = np.random.uniform(0, 1, (1, 7))
W = W/W.sum()
q = 0.5

solver = PermutationSampler()
solver.solve_game(W, q)
shapley_values = solver.get_solution()

Methods Included

In detail, the following methods can be used.
