Midterm 1 Answer 15mp4

  • 0:01 - 0:10
    Now, the first answer is two-third, and the reason is we observed A once, and this was all we observed.
  • 0:10 - 0:14
    So maximum life would give us a probability of one, but because we used Laplacian smoothing,
  • 0:14 - 0:19
    and there's two different possible states, we add one, as before, which makes two-thirds.
  • 0:19 - 0:29
    Two-thirds is also the correct answer for the next question. There's one, two, three, four transitions out of A,
  • 0:29 - 0:37
    three of which leads to A again. So maximum life would give us three-quarters, but because we do Laplacian smoothing,
  • 0:37 - 0:43
    we add one fake transition over here, and there could've been two of those, one to A and one to B, we had two over here,
  • 0:43 - 0:50
    which is four over six or two over three. And there's no transition out of B in this example.
  • 0:50 - 0:57
    So for maximum life we wouldn't even know what to say. But in our case, with Laplacian smoothing, we add one fake observation
  • 0:57 - 1:02
    divided by two as a denominator, so we get half for the last question.
