SPAD-SoCとあるが、チップはソニーかな

計算装置としてのGPUの記事が気になる

そういえば最近DeepL使わなくなってしまった

I’ve decided to leave OpenAI. Below is the note I shared with my team. Building Sora zero-to-one with you all has been the honor and adventure of a lifetime. As this team knows well, one of the best parts of working on video is that you can see the scaling behavior with your own eyes, and there have been a lot of oh-shit moments over the years. About a month into Sora, way back when this was just a tiny two-man effort, we saw a sample where a land shark swam by a bunch of intricate cacti in a desert (it was a weird prompt), and the details of each cactus were perfectly preserved once the shark passed. We had never seen object permanence like this in any video model. That’s when we knew we were onto something. It’s amazing how much the Overton window has shifted on video models. OpenAI has a high tolerance for crazy moonshots, but even back in July 2023 there was a ton of skepticism that high-fidelity 1080p multi-shot generation was achievable within a year given the state of video in the broader industry. We managed to get there 7 months later. While the original Sora ignited a huge amount of investment in video across the industry, it took the next generation of models with Sora 2 for the broader public to understand the transformation happening. I’m proud of all the sleepless nights before and after the launch this team endured in order to deploy the technology in a responsible way and help steer societal norms. I am immensely grateful to Sam, Mark, Aditya and Jakub for fostering a research environment that allowed us to pursue ideas off-the-beaten path from the company’s mainline roadmap. It’s tempting in life to mode collapse to the most important thing, but cultivating entropy is the only way for a research lab to thrive long-term, and Sam deeply understands this. Sora was a project that could not have happened anywhere but OpenAI, and I will always deeply love this place for that. I’m going to miss this team a lot, but there are great things on the horizon for all of you. I will always be in your guys’ corner cheering you on. Love, Bill

このサーベイ論文は勉強になりそうです

📢 We release "Feed-Forward 3D Scene Modeling: A Problem-Driven Perspective" — a comprehensive survey covering 200+ papers on feed-forward 3D reconstruction! Instead of categorizing by 3D representations, we propose a problem-driven taxonomy. 🌐 ff3d-survey.github.io

@bluebacks_pub 早く読みたい

皆さん！もうすぐ光り輝くブルーバックスが発売されます。 〈なぜ帯にホログラムが貼ってあるのか？〉 勘の良い方はお気づきになるかもしれません。 いま世界中の物理学者が注目する「あの原理」の 一般書が登場します！ 著者は、理論物理学者の橋本幸士先生。 4月23日の発売をお楽しみに！！

感情を推定するという技術は定期的にいろんな会社から出てきては消えているが、今だまともに使える技術としては実現指定ない。そもそも感情という定義の難しいものを数値化するのが難しい。ソニーも何度目かの挑戦だろうがどうアプローチするのか興味がある。 forbesjapan.com/articles/detai…

What if I told you any shape can be broken down into circles? This visualization demonstrates the stunning power of the Fourier Transform. By using a series of rotating vectors—known as epicycles—we can reconstruct complex, continuous paths from simple circular motions. Each circle represents a specific frequency, phase, and amplitude. When these rotating arrows are added together, the resulting "tip" traces out the intricate outline you see here. It’s where pure mathematics meets digital art, proving that even the most complex designs are just a symphony of oscillations. Credit: mathswithmuza

Ready… set… Earth! 🌎 As Artemis II flew around the far side of the Moon, the crew captured a new view of home. These images show Earthset, when Earth dips below the lunar horizon. Parts of Australia & Oceania are visible, while the dark side of Earth is experiencing nighttime.

Hello, Moon. It’s great to be back. Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: nasa.gov/artemis-ii-mul…

Watch hydrogen atom wavefunctions smoothly transition between quantum states (n,l,m) This is the actual probability density of finding the electron; not just static orbitals, but the real quantum dance as it morphs between energy levels.

アルテミス計画で月へ向かっている宇宙飛行士が取った地球の姿。普段よく見る宇宙ステーションからの地球と異なり、地球全部が見えますね。

日本の僧侶、貴族、天皇たちが1200年にわたり、桜の記録を細かく残し続け、偶然にも世界最長の気候データセットを構築していたと世界中で話題に 本当に貴重な資料だと思います

Liftoff. The Artemis II mission launched from @NASAKennedy at 6:35pm ET (2235 UTC), propelling four astronauts on a journey around the Moon. Artemis II will pave the way for future Moon landings, as well as the next giant leap — astronauts on Mars.
