End-to-End Dynamic Metasurface Antenna Wireless System: Prototype, Opportunities, and Challenges
Dynamic metasurface antennas (DMAs) are a promising hybrid analog/digital beamforming technology to realize next-generation wireless systems with low cost, footprint, and power consumption. The research on DMA-empowered wireless systems is still at an early stage, mostly limited to theoretical studies under simplifying assumptions on the one hand and a few antenna-level experiments on the other hand. Substantial knowledge gaps arise from the lack of complete end-to-end DMA-empowered wireless sy…

@… Sorry, I overlooked the mention.
I forked the Crystal-lang relay that was once maintained on Mastodon, and added the ability to set conditions for the Activity to be relayed. By default, it only relays Notes with a ha…

Introduction to Predictive Coding Networks for Machine Learning
Predictive coding networks (PCNs) constitute a biologically inspired framework for understanding hierarchical computation in the brain, and offer an alternative to traditional feedforward neural networks in ML. This note serves as a quick, onboarding introduction to PCNs for machine learning practitioners. We cover the foundational network architecture, inference and learning update rules, and algorithmic implementation. A concrete image-classification task (CIFAR-10) is provided as a benchmark…

Dezentrale Netze wie das Fediverse sind die natürliche Form des Internets, deren Brücken aufgrund der Geschäftsmodelle der heute etablierten sozialen Netzwerke bewusst gekappt wurden. TikTok, Instagram, Facebook, schließen die Benutzer ein und widersprechen grundsätzlich der ursprünglichen Vision des Internets:
"There is the idea that society can run without a hierarchical bureaucratic government being involved at every step, if only we can hit on the right set of rules for peer-p…
