Project description

Confusion matrix tool.

Further information:

Instalation

From source code:

python setup.py install

From pypi:

pip intall confumatrix

Usage

>>> from confumatrix import ConfuMatrix
>>> cm = ConfuMatrix(a=10, b=1, c=10, d=3)
>>> cm.accuracy()
0.5416666666666666
>>> cm.precision()
0.9090909090909091
>>> cm.recall()
0.5
>>> cm.specificity()
0.75
>>> cm.sensitivity()
0.5
>>> cm.f1()
0.6451612903225806
>>> print cm

binary_classification.py

Load a yaml file with results of a binary classfication and prints Confusion matrix for that results.

Input file format:

# Languages that can be detected
types: [en, es, pt, it, de]
umbral: 0.5
sample:
  - result:
      en: 0.1
      es: 0.2
      pt: 0.3
      it: 0.6666  #hit! ( 0.6666 > 0.5 )
      de: 0.3
    expected: de
  - result:
      en: 0.2
      es: 0.99 # hit
      pt: 0.98 # hit
      it: 0.4
      de: 0.3
    expected: es
