Introduction

The glmnet-classifier project provides GlmnetClassifier for the classification and prediction for two classes, the binomial case. GlmnetClassifier is based on glmnet. A fortran compiler is required.

GlmnetClassifier is designed for use with scikit-learn pipelines and composite estimators.

Example

from glmnet_classifier import GlmnetClassifier
from sklearn.datasets import make_classification
from sklearn.model_selection import train_test_split

Make a classification problem

seed = 42
X, y = make_classification(
    n_samples=30,
    n_features=5,
    n_informative=2,
    n_redundant=2,
    n_classes=2,
    random_state=seed
)
X_train, X_test, y_train, y_test = train_test_split(X, y, random_state=seed)

Train the classifier

cls = GlmnetClassifier().fit(X_train, y_train)

Get the score on unseen data

cls.score(X_test, y_test)
