Problems

  1. Mary and her temperature preferences: Imagine that you know that your friend Mary feels cold when it is -50 degrees Celsius, but she feels warm when it is 20 degrees Celsius. What would the 1-NN algorithm say about Mary; would she feel warm or cold at the temperatures 22, 15, -10? Do you think that the algorithm predicted Mary's body perception of the temperature correctly? If not, please, give the reasons and suggest why the algorithm did not give appropriate results and what would need to improve in order for the algorithm to make a better classification.
  2. Mary and temperature preferences: Do you think that the use of the 1-NN algorithm would yield better results than the use of the k-NN algorithm for k>1?
  3. Mary and temperature ...
