Sophisticate Confusion Matrix
Project description
conf-mat
This library was created to address the confusion in confusion matrices and classification reports generated by libraries like scikit-learn. It displays confusion matrices and their heatmaps in a more aesthetically pleasing, intuitive way. It also presents classification reports and accuracy rates in a manner that clarifies the calculation method and how those results were obtained, which can help alleviate confusion for beginners in machine learning
Installation
You can install conf-mat via pip:
pip install conf-mat
Usage
For Binary Classification
from numpy.random import randint
from matplotlib.pyplot import show
from conf_mat import print_conf_mat, plot_conf_mat, conf_mat_to_html
y_true = randint(0, 2, 1000)
y_pred = randint(0, 2, 1000)
# Show The Confusion Matrix On The Console (Classes Names Are Not Mandatory)
print_conf_mat(y_true, y_pred, classes_names=[False, True])
# Show The Confusion Matrix As A Heat Map (Classes Names Are Not Mandatory)
plot_conf_mat(y_true, y_pred, classes_names=[False, True])
show() # If You Are Using VSCode And You Are Executing The Code Direcctely
# Show The Confusion Matrix As It Appears On The Console And As A Heat Map On The HTML Page (Classes Names Are Not Mandatory)
conf_mat_to_html(y_true, y_pred, classes_names=[False, True])
Output
