Normalizing Flows Are Capable Generative Models

news.ycombinator.com Unknown 2026-02-22 21:50:10

Normalizing Flows (NFs) are likelihood-based models for continuous inputs. They have demonstrated promising results on both density estimation and generative modeling tasks, but have received relatively little attention in recent years. In this work, we demonstrate that NFs are more powerful than previously believed. We present TarFlow: a simple and scalable architecture that enables highly performant NF models. TarFlow can be thought of as a Transformer-based variant of Masked Autoregressive Fl

The Effect of Noise on Sleep

Jun 26, 2025 The effect of noise on sleep Brandon Ballinger How detrimental is noise for your sleep? Andrej Karpathy raised this exact question in a tweet. The answer to Karpathy’s question is, well, empirical, with a rough experiment suggested by Paul Graham: Consumer devices like Apple Watch measure many sleep metrics, including sleep stages, heart rate variability, and heart rate. The Apple Watch’s microphone also measures noise in fine-grained frequency, which can be filtered down to times

Apple Research unearthed forgotten AI technique and using it to generate images

news.ycombinator.com Marcus Mendes 2026-02-20 23:19:47

Today, most generative image models basically fall into two main categories: diffusion models, like Stable Diffusion, or autoregressive models, like OpenAI’s GPT-4o. But Apple just released two papers that show how there might be room for a third, forgotten technique: Normalizing Flows.

A Review of Aerospike Nozzles: Current Trends in Aerospace Applications

news.ycombinator.com Cardenas 2026-02-26 16:33:10

The design of rocket nozzles aims to expand the combustion gases until the exit pressure matches the ambient pressure, thereby maximizing thrust. However, ambient pressuredecreases as the rocket ascends, posing a challenge for conventional nozzles, which operate efficiently only at a specific altitude [ 30 ]. By adjusting their flow characteristics to the varying atmospheric pressure, aerospike nozzles offer a significant advantage in this regard. To quantify this impact, the thrust coefficient
