Lasso Regression
This module contains an implementation of Lasso Regression, a linear regression technique with L1 regularization.
Overview
Lasso Regression is a regression algorithm that adds a penalty term based on the absolute values of the coefficients. This penalty term helps in feature selection by driving some of the coefficients to exactly zero, effectively ignoring certain features.
Usage
To use Lasso Regression, follow these steps:
- Import the
LassoRegression
class. - Create an instance of the class, specifying parameters like learning rate, lambda (regularization strength), and the number of iterations.
- Fit the model to your training data using the
fit
method. - Make predictions using the
predict
method.
Example:
from LassoRegression import LassoRegression
lasso_model = LassoRegression(learning_rate=0.01, lambda_param=0.1, n_iterations=1000)
lasso_model.fit(X_train, y_train)
predictions = lasso_model.predict(X_test)
Parameters
learning_rate
: The step size for gradient descent.lambda_param
: Regularization strength (L1 penalty).n_iterations
: The number of iterations for gradient descent.
