Defined the very best method: with cats!

Why is AI-generated synthetic data all the craze lately? On this article, I’ll clarify my favourite method: with cats!

Let’s say I wish to prepare a cat-not-cat classifier from scratch, however I solely have one photograph to work with:

The creator’s cat, Huxley.

Effectively, if I can’t gather them and I can’t purchase them, then I’ll should make them myself. Behold, my creation:

Your creator is a veritable Michelangelo.

No good? Yeah, drawing was by no means my robust swimsuit. One other method to make faux information is to repeat present datapoints, besides this isn’t going to be a lot use for offering educational selection.

This method fools nobody. I’ve nonetheless solely successfully received one datapoint.

It’ll be like instructing a human scholar by giving them the identical instance again and again, so all they study is that one factor. If my dataset is 30,000 copies of this Huxley photograph…
