Entropy Calculation Part 1 - Intro to Machine Learning

  • 0:01 - 0:02
    Now let's do an example.
  • 0:02 - 0:07
    So here's your reminder of the formula and suppose this is my data.
  • 0:07 - 0:11
    I have four data points and for each data point I have three features,
  • 0:11 - 0:18
    the grade of the train, the bumpiness, whether there's a speed limit,
  • 0:18 - 0:21
    and then the speed that the car goes.
  • 0:22 - 0:23
    And i'm just making up some data here.
  • 0:23 - 0:27
    So let's start out at the top of the decision tree here.
  • 0:27 - 0:32
    So I have two slow examples and two fast examples.
  • 0:32 - 0:36
    Slow, slow, fast, fast.
  • 0:36 - 0:39
    So the first question is, what's the entropy of this node?
  • 0:40 - 0:43
    So let's do this piece by piece.
  • 0:43 - 0:47
    How many of the examples in this node are slow?
  • 0:47 - 0:48
    Write your answer here.
