model-contrast 0.1.8

Compare two ML models.

Models Contrast

A simple package for compare the performance of two ML models in sklearn, python.

Installation

Use the package manager pip to install model-contrast.

pip install model-contrast

Usage

Compare 2 Binary Classifiers

from sklearn.datasets import make_classification
from sklearn.ensemble import RandomForestClassifier
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import train_test_split

# create two demo models
X, y =  make_classification(n_samples=700, random_state=42)
X_train, X_test, y_train, y_test = train_test_split(X, y,
         test_size=0.2, random_state=42)

model1 = RandomForestClassifier(n_estimators=10, random_state=42)
model2 = LogisticRegression()

#train the models
model1.fit(X_train, y_train)
model2.fit(X_train, y_train)

Now let's compare them with our package:

from model_contrast import classificator_contrast

classificator_contrast(model1, model2, X_test, y_test)

and it return:

Compare Multi-Class Classifiers

from sklearn.datasets import make_classification
from sklearn.ensemble import RandomForestClassifier
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import train_test_split

# create two demo models
X, y =  make_classification(n_samples=700, random_state=42, n_classes=4, n_informative=4)
X_train, X_test, y_train, y_test = train_test_split(X, y,
         test_size=0.2, random_state=42)

model1 = RandomForestClassifier(n_estimators=10, random_state=42)
model2 = LogisticRegression()

#train the models
model1.fit(X_train, y_train)
model2.fit(X_train, y_train)

Compare them:

from model_contrast import classificator_contrast

classificator_contrast(model1, model2, X_test, y_test)

and it returns:

Compare 2 Regressors

from sklearn.datasets import make_regression
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
from sklearn.ensemble import RandomForestRegressor

#create the regressor
X, y =  make_regression(n_samples=700, random_state=42)
X_train, X_test, y_train, y_test = train_test_split(X, y,
         test_size=0.2, random_state=42)

model1 = RandomForestRegressor(n_estimators=10, random_state=42)
model2 = LinearRegression()

#train the regressors
model1.fit(X_train, y_train)
model2.fit(X_train, y_train)

Compare them:

from model_contrast import  regressor_contrast

regressor_contrast(model1, model2, X_test, y_test)

and it returns:
