The Automated Flying Pigeon of Archytas

Dennis Lee — Sun, 10 May 2026 04:59:48 +0000

Around 400 BCE, the Greek mathematician Archytas of Tarentum built a wooden bird propelled by trapped steam or compressed air that flew about 200 meters. This marked the transition from myth to real-world engineering, proving physical machinery could simulate the biological behavior of animals.

The Theoretical Scaling Limits of Deep Stacked Denoising Autoencoders

Dennis Lee — Mon, 04 May 2026 06:30:42 +0000

Pascal Vincent, Hugo Larochelle, Yoshua Bengio, and Pierre-Antoine Manzagol introduced denoising autoencoders. By forcing the network to reconstruct clean data from inputs artificially corrupted by noise, they proved that deep layers could independently learn highly robust, abstract structural features of the environment.
