ajayarunachalam / regressormetricgraphplot

Python package to simplify plotting of common evaluation metrics for regression models. Metrics included are pearson correlation coefficient (r), coefficient of determination (r-squared), mean squared error (mse), root mean squared error(rmse), root mean squared relative error (rmsre), mean absolute error (mae), mean absolute percentage error (mape), etc.

Common Evaluation metrics graph plot for Regression Problem

Description

PyPI: https://pypi.org/project/regressormetricgraphplot/

Python implementations for comparing different Regression Models and Plotting with their most common evaluation metrics.

The purpose of this package is to help users plot the graph at ease with different widely used metrics for regression model evaluation for comparing them at a glance

Illustration Example

# Importing libraries 
from sklearn.datasets import make_regression
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
from regressormetricgraphplot import *
%matplotlib inline

#Let's load a simple dataset and make a train & test set :
X, y = make_regression(n_samples=1000, n_features=10, n_informative=7, n_targets=1, random_state=0)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=10)

# Train the regressor and predict on test set 
# Fitting training set to linear regression model
lr = LinearRegression(n_jobs=-1)
lr.fit(X_train, y_train)
# Predicting
y_pred = lr.predict(X_test)

We can now use R2AndRMSE to compute & output R-squared, and Root Mean Square Error.

# Metrics
CompareModels.R2AndRMSE(y_test=y_test, y_pred=y_pred)

Make object of the class CompareModels

plot = CompareModels()

We can now use add & show method to add the built model & plot the graph at ease with all the evaluated metrics.

plot.add(model_name='Linear Regression', y_test=y_test, y_pred=y_pred)
plot.show(figsize=(10, 5))
