• Implement RidgeRegression.train in ridge_regression.py
• Implement Logistic._iteration_step in logistic_regression.py
• Implement Logistic.predict_proba in logistic_regression.py
• Run python3 test.py to verify your implementation

For each question, there are 3 tests test.py:

• Pass all 3 tests: 5 score
• Pass 2 tests: 4 score
• Pass 1 test: 3 score
• Pass 0 test: 2 score

You can use test filter to only run partial test in your environment. For example, to run only ridge regression test, use the command python3 test.py TestRidgeModel. This could help you focus on debugging one model at each time.
