ruDALL-E: Generating Images from Text. Facing down the biggest computational challenge in Russia

Multimodality has led the pack in machine learning in 2021. Neural networks are wolfing down images, text, speech and music all at the same time.  OpenAI is, as usual, top dog, but as if in defiance of their name, they are in no hurry to share their models openly.  At the beginning of the year, the company presented the DALL-E neural network, which generates 256x256 pixel images in answer to...

And since my former colleague Alexei Stennikov and I were directly involved in finding this vulnerability, I would like to share some details. Read more Read more

Экономика как целое: холистический подход vs частная перспектива

Неоклассическая, она же неолиберальная, экономическая парадигма, отличается индивидоцентричностью. Это — слепое пятно современной мейнстрим-экономики. 100% создаваемого в экономике богатства — это сумма труда 100% работающих в экономике людей. Например, 110 триллионов рублей ВВП России в 2019 году — это совокупная ценность продуктов труда 73 миллионов человек. Но совокупная ценность труда в экономике не равна сумме ценности труда 73 миллионов индивидов. В ВВП считается ценность конечного продукта. Это в Сре Read more
