Welcome to the SKGA repository! This repository contains the skga package, which is a Python library for performing machine learning hyperparameters optimization.
To install the skga package, follow these steps:
-
Make sure you have Python 3.9 installed on your system.
-
Open a terminal or command prompt.
-
Run the following command to install the package using pip:
pip install skga
This will automatically download and install the
skgapackage along with its dependencies.
Once you have installed the skga package, you can start using it in your Python projects. Here's a basic example to get you started:
from sklearn import svm, datasets
from sklearn.model_selection import train_test_split
from skga import HyperBRKGASearchCV
# Load the Iris dataset
irisX, irisY = datasets.load_iris(return_X_y=True)
# Split the dataset into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(irisX, irisY, test_size=0.5, random_state=0)
# Define the parameters for the SVM classifier
parameters = {'kernel': ('linear', 'rbf'), 'C': [1, 10]}
# Create an SVM classifier
svc = svm.SVC()
# Create a HyperBRKGASearchCV instance
clf = HyperBRKGASearchCV(svc, parameters=parameters, data=X_train, target=y_train)
print("# Optimizing hyperparameters for accuracy\n")
# Fit the classifier to the training data
clf.fit(X_train, y_train)
print("Best combination of parameters found in the training set:\n")
print(clf.cv_results_['best_param_decoded'])
print()
print("Scores of HyperBRKGA in the training set:\n")
print(clf.cv_results_)This example demonstrates how to use the HyperBRKGASearchCV class from the skga package to perform hyperparameter optimization for an SVM classifier.
