Table of Confusion
When the classification function is not perfect, false results will appear. The example confusion matrix below, of the 8 actual cats, a function predicted that three were dogs, and of the six dogs, it predicted that one was a rabbit and two were cats. We can see from the matrix that the system in question has trouble distinguishing between cats and dogs, but can make the distinction between rabbits and other types of animals pretty well.
| Predicted | ||||
|---|---|---|---|---|
| Cat | Dog | Rabbit | ||
| Actual | Cat | 5 | 3 | 0 |
| Dog | 2 | 3 | 1 | |
| Rabbit | 0 | 2 | 11 | |
When dealing with binary classifications these concepts are simpler

Famous quotes containing the words table of, table and/or confusion:
““A sigh for every so many breath,
And for every so many sigh a death.
That’s what I always tell my wife
Is the multiplication table of life.””
—Robert Frost (1874–1963)
“... So damn your food and damn your wines,
Your twisted loaves and twisting vines,
Your table d’hôte, your à la carte,
. . . .
From now on you can keep the lot.
Take every single thing you’ve got,
Your land, your wealth, your men, your dames,
Your dream of independent power,
And dear old Konrad Adenauer,
And stick them up your Eiffel Tower.”
—Anthony Jay (b. 1930)
“The confusion is not my invention. We cannot listen to a conversation for five minutes without being aware of the confusion. It is all around us and our only chance now is to let it in. The only chance of renovation is to open our eyes and see the mess. It is not a mess you can make sense of.”
—Samuel Beckett (1906–1989)
