```python kf = KFold(n_splits=5, random_state=0, shuffle=True) rmse = lambda y, y_pred: np.sqrt(mean_squared_error(y, y_pred)) scorer = make_scorer(rmse, greater_is_better=False) ``` ```python def random_search(model, grid, n_iter=100): n_jobs = max(cpu_count() - 2, 1) search = RandomizedSearchCV(model, grid, n_iter, scorer, n_jobs=n_jobs, cv ...

Also fit each of a ridge, lasso, and elastic net regression on the same data. Use the function cv.glmnet to cross-validate and find the best values of \(\lambda\) . For elastic net, try a few values of \(\alpha\) as well.

the techniques for fitting linear regression model can be used for fitting the polynomial regression model. For example: 2 yxx 01 2 or 2 E()yxx 01 2 is a polynomial regression model in one variable and is called a second-order model or quadratic model. This course generalizes the content of Regression Analysis and explores two main topics in Data Mining: prediction and classification. Clustering and Association Rules will also be discussed. Many real-life problems can be categorized into these topics.
