1994 gave humanity lots of cool things, but without a doubt, one of my highlights is Greg Egan's book "Permutation City."
The book is especially relevant now that we started talking about multiverses once again. Once everything becomes digital, how would one distinguish between computer simulations of people and real people themselves? Also, when our consciousness becomes a series of bits, amenable from the outside, how would it feel to have one's entire past and present modified and re-created with or without one's consent?
I won't spoil the book further. I just wanted to mention it because it served as my inspiration while generating the series of images (accordingly called Fractal City) below:
One sees multiple variations of the same primary input turned into pieces of AI art by an algorithm called VQGAN+CLIP. The abbreviation became a hot topic recently among artists and scientists alike. In very simple terms, it uses a variation of the Generative Adversarial Network (GAN) idea that became synonymous with deep-fakes and projects like This Person Does Not Exist. A GAN consists of two networks. One tries to "fool "the other by making better and better representations of an original target
For example, when talking about faces, the generator will start with a series of randomly colored pixels, iteratively refining the output until its counterpart (the discriminator) says, "It's a face!"
Until now, GAN's were limited in what they could generate, based on the initial training data they were fed with. A GAN trained to generate faces, for example, won't be able to imagine a car. That is where CLIP enters the stage.
Developed by Open AI, CLIP is a neural network model able to infer (I think the word "imagine" sits better here) image feature based on human text. Without any limitations on what the text prompt can be.
There you have it- feeding GLIP with your imaginary text prompt will make it" train" your GAN with the image features that match the teat. The rest is GAN doing its best.
