This Is What Happens When You Let Artificial Intelligence Get Artistic

Beauty can be anything, when the eye of the beholder belongs to an AI system.

This Is What Happens When You Let Artificial Intelligence Get Artistic

Artificial Intelligence (AI) is being used for everything from facial recognition software to chat bots that interact with a company's potential customers.

But what about the artistic side of AI?

Some researchers want to discover what happens when they give their neural networks a chance to show their creative side -- and the results are surreal to say the least.

Neural networks go naked

AI researcher Robbie Barrat fed a Generative Adversarial Network (GAN) thousands of nude portraits from a dataset and then trained it to create its own version of the artwork it processed. The results of the AI art of surreal, swirly naked female forms would impress even the likes of Salvador Dali.

Generative adversarial networks are artificial intelligence algorithms that are used in unsupervised machine learning. It uses two different neural networks -- a generator and a discriminator.

The generator tries to come up with images that fools the discriminator, and the discriminator tries to learn how to tell the difference between real images from the dataset and fake images the generator feeds it. Over time, the more realistic the output will be -- in this case nude paintings.

However sometimes the generator and discriminator will keep trying to fool each other without actually getting better at the task at hand. And in the case of Barrat's neural network, the artwork looks like a surrealist nightmare.

Unhappy little trees

The MIT-trained roboticist and artist Alexander Reben, uses his art to explore what goes wrong when machine learning filters a seemingly innocent episode of the PBS retro TV show "The Joy of Painting" through the neural net.

In the video "Deeply Artificial Trees" by Reben's artist pseudonym Artboffin, we see the PBS show host, artist Bob Ross, looking less like the '70s art icon who loved to paint calming landscapes, and more like a character featured in a bad acid trip.

The video shows the "happy, little trees" Ross is famous for painting re-imagined as horrific-looking Lovecraftian insects summoned by the fictional grimoire, the Necronomicon.

"This artwork represents what it would be like for an AI to watch Bob Ross on LSD (once someone invents digital drugs)," artBoffin writes in the video description. "It shows some of the unreasonable effectiveness and strange inner workings of deep learning systems. The unique characteristics of the human voice are learned and generated, as well as hallucinations of a system trying to find images which are not there."

AI explores dragons and romance

Sometimes dragons and candy hearts are the the perfect muse for a neural network. Janelle Shane, a research engineer for an optics company who also likes to experiment with neural-network programming, trained a machine-learning system to create new monsters for the fantasy tabletop game, Dungeons & Dragons.

Shane gathered 2,205 creature names from the second-edition Dungeons & Dragons monster manual, and her neural network transformed those names into new imaginary creatures like a Curple Lard Dragon, Wolfworm, Spectral Slug, Jabberwont, Burglestar and Marraganralleraith.

She then created a recurrent neural network algorithm to generate D&D spells like Barking Sphere, Hold Mouse and Gland Growth.

Shane also trained her machine-learning system to generate new romantic phrases for Valentine's Day candy hearts. Instead of the typical "Be Mine" message, the AI came up with "Hot Give" "Team Bear" and "Time Hug."

The surrealist art movement seems boringly normal compared to this new wave of AI artists. Here's hoping one day, art museums everywhere will have wing dedicated to the neural networks making this unusual art, and the humans who trained them.
