Latent space walk

Latent space walk

The project attempts to explore the processes of machine learning and neural networks through their unconventional and somewhat counterintuitive use. It depicts the process of training a neural network all the way from collecting the initial images to animating its final products. The principle that the project explores is related to the processes of training in computer vision, where neural networks are exposed to thousands of images of specific objects, and the “algorithmic summary” created along the way changes with every image and gradually approaches some kind of a visual essence of individual objects. What is specific about this project is that the initial database used is not homogenous, but the product of a generative process. It is therefore first and foremost an experiment – we don’t know how the neural network will interpret the distinctly diverse bank of images, and we’re interested in how the final product will reflect the nature of the process.

The work is conceived as a video installation with two monitors. The first monitor displays a generative collage, animated on a local server by using a pixi.js javascript library. The collage is composed from an enormous number of different images with a completely random rate of occurrence, size, transparency and location. A computer makes a screenshot of the first screen every 15 seconds, crops these images into the 1280 x 768 format with the ImageMagick program and sends them to the server. These images are used as a dataset for machine learning by the GAN (generative adversarial network), StyleGAN2 to be exact, that then forms a unique algorithmic approximation to the set of these generative collages. This, in turn, can be used ad infinitum to generate new images that are based on the initial images, animate the transitions between them and display these on the second, larger screen.

Although the broad collection of images that form the initial visual bank, displayed on the first screen, seems completely random, it is loosely based on the author’s visual interests and therefore forms a unique moodboard. The work can therefore be understood as an anticipation of future creative processes enriched with neural networks, where artists equipped with such tools will be able to create new content through associative combinatorics alone.
