Hi and welcome back to Chapter 11 where we start taking a look at the confusion matrix which is confusing

2
00:00:06,930 --> 00:00:13,340
for now but it's very helpful and also viewing all the data that gets misclassified by our classifier.

3
00:00:13,560 --> 00:00:18,660
It's very important to look at this data sometimes because we need to know exactly what are classified

4
00:00:18,690 --> 00:00:21,580
what's wrong and why.

5
00:00:21,590 --> 00:00:23,820
So let's look at the contents in this chapter it's fairly simple.

6
00:00:23,830 --> 00:00:28,600
Eleven point one and basically deals with the confusion matrix and eleven point two deals with misclassified

7
00:00:28,600 --> 00:00:30,710
data and how we can view them.

8
00:00:30,710 --> 00:00:30,990
OK.

9
00:00:31,000 --> 00:00:32,980
So let's get started on eleven point one.
