Here in confusion matrix, 25 should be true negative, instead of true positive.
The output layout of is different from what we saw in regular confusion matrix.

On 17:34 you said that the test data should not be scaled.
On 18:42 you scale x_test.
I'm a bit confused.

The number of predictions(n) depends on what??
If we have 5000 test data, what will be the number of predictions(n) for confusion matrix?
