404.zero utilise neural networks and analog synthesisers in Deep Echo The audiovisual work is now available to buy as an NFT at SuperRare. In the second of a series of four NFTs being made available for auction by 404.zero in partnership with Fact at SuperRare, the Russian multidisciplinary duo utilise Natural Intelligence (NI), a system that uses real-life data to train a natural neural network, to generate an audiovisual piece in real time. “The most important component to any intelligence in this field is how it integrates all aspects,” 404.zero says of Deep Echo, which is currently up for auction. “We use all the tools to build a human learning algorithm that is capable of predicting the best possible output, even in the absence of significant performance gains.”
