Q:

Which figure represents an overfitted model?

Q:

True or false: The model that best minimizes training error is the one that will perform best for the task of prediction on new data.

Q:

Question 3 The following table illustrates the results of evaluating 4 models with different parameter choices on some data set. Which of the following models fits this data the best? Model index Parameters (intercept, slope) Residual sum of squares (RSS) 1 (0,1.4) 20.51 2 (3.1,1.4) 15.23 3 (2.7, 1.9) 13.67 4 (0, 2.3) 18.99  

Q:

Assume we fit the following quadratic function: f(x) = w0+w1*x+w2*(x^2) to the dataset shown (blue circles). The fitted function is shown by the green curve in the picture below. Out of the 3 parameters of the fitted function (w0, w1, w2), which ones are estimated to be 0? (Note: you must select all parameters estimated as 0 to get the question correct.)

Q:

Which of the following plots would you not expect to see as a plot of training and test error curves?

Q:

True or false: One always prefers to use a model with more features since it better captures the true underlying process.
