Problem 3: Compare Different Alpha Values

Problem Description

Write a Python program that trains Ridge regression models with alpha values of 0.1, 1, and 100, comparing how the coefficient magnitudes shrink as alpha increases.

Input

A dataset with numeric features.

Output

The coefficients for each alpha value.

Constraints

• At least 5 data points.

Example Input

text
(A dataset with 2 features across 5 rows)

Example Output

text
alpha=0.1: [4.8, 2.1]
alpha=1: [3.9, 1.7]
alpha=100: [0.5, 0.3]

Concepts Covered

Ridge, alpha parameter, coefficient shrinkage.
