  4. principles.

17. Consider a binary classification problem. Suppose I have trained a model on a linearly separable training set, and now I get a new labeled data point which is correctly classified by the model, and far away from the decision boundary. If I now add this new point to my earlier training set and re-train, in which cases is the learnt decision boundary likely to change?

  1. When my model is a perceptron and logistic regression.
  2. When my model is logistic regression and Gaussian discriminant analysis.
  3. When my model is an SVM.
  4. When my model is a perceptron

18. Data used to build a data mining model.

  1. validation data
  2. training data
  3. test data
  4. hidden data

19. Data used to optimize the parameter settings of a supervised learner model.

  1. training
  2. test
  3. verification
  4. validation

20. Generalization error measures how well an algorithm perform on unseen data. The test error obtained using cross-validation is an estimate of the generalization error. Is this estimate unbiased?

  1. Yes
  2. No
