Be sure to check out the picturesque Starfield Library! Also located within the Coex complex.

Being at #ICML2026, new to the community, and trying to meet people. Have fun @HThasarathan and make sure to network! Harry will be previewing our new work on cross-model circuit discovery at the Mech Interp Workshop.

On my to ICML 🇰🇷. Will present our Linearizer paper on Tuesday, July 7 at 10:30 AM poster session. Come and say hi! I’m happy to meet and chat about research, so please feel free to reach out and we can have a coffee together.
They tell you neural nets are non-linear. What does "linear" even mean?! Linearity is only defined given two vector spaces, X → Y. What if we could find a different pair of spaces where NNs ARE linear? 🤯 We do it and use it for many apps, such as one-step diffusion! 🧵

🚀 **What if 3D generation did not need a complicated cascade of models?** Most recent 3D asset generation pipelines still follow a multi-stage recipe: 🖼️ generate multi-view images → 🧱 reconstruct geometry → 🔁 convert representations → 🛠️ refine artifacts… and hope that errors do not accumulate along the way. In our new paper, **PixGS: Pixel-Space Diffusion for Direct 3D Gaussian Splat Generation**, accepted at **ECCV 2026** 🎉, we ask a simpler question: > Can we generate 3D Gaussian Splats directly — in a single stage — while preserving fine-grained geometry and appearance? Our answer is **PixGS** ✨, a pixel-space diffusion framework that directly denoises 3D Gaussian attributes instead of relying on lossy latent compression. This allows the model to regularize the generated asset at the **splat level** 🎯, improving both geometry and appearance while avoiding many decoding artifacts seen in latent/cascade pipelines. The key idea is to bring the strength of large 2D generative priors into 3D generation 🌍, but without forcing the 3D representation through a compressed latent bottleneck. PixGS uses richer supervision signals — including 🔹 RGB 🔹 depth 🔹 surface normals 🔹 high-frequency structural cues to better preserve object details and view consistency. The result: high-quality text/image-conditioned 3DGS generation with strong performance and fast inference — around **1 second on a single A100 GPU** ⚡. I’m especially excited about this direction because 3D Gaussian Splatting has already transformed how we render and represent scenes. PixGS suggests that the next bottleneck may not be rendering anymore, but how cleanly, directly, and efficiently we can **generate** 3D assets in the first place. 📄 Paper: arxiv.org/abs/2607.01803 Huge thanks to my co-author Cao Duy and everyone who supported this work! 🙌 #ECCV2026 #ComputerVision #GenerativeAI #3DGeneration #GaussianSplatting #DiffusionModels #AIResearch #Graphics #Robotics #QualcommAIResearch

Prompt source
Do You also wanted to make a playful portrait ? Select Model GPT Image 2 in @openart_ai Here is the Prompt: Ultra-realistic playful studio portrait of a young Indian woman with fair porcelain skin, expressive dark brown eyes, soft feminine facial features, glossy natural lips, and long black hair styled in a messy low bun with a few loose strands framing her face, wearing pearl earrings and smiling joyfully while running across a seamless light gray studio background. She is captured mid-stride with one leg lifted, laughing with a genuine happy expression. She wears an oversized cream sweatshirt and loose beige trousers with white sneakers, creating a stylish casual editorial look. In her hand, she holds a cute plush teddy bear and a bunch of pastel balloons. Behind her, a simple black hand-drawn cartoon stick figure grabs and stretches the back of her oversized sweatshirt, making the fabric appear elastically pulled as if the doodle is trying to stop her from running away. The doodle character has a funny shocked face, tiny legs, expressive eyes, and playful motion lines. Minimalist composition, clean high-key studio lighting, soft shadows beneath her feet, ultra-sharp focus, realistic skin texture, vibrant yet natural colors, whimsical editorial photography, premium fashion campaign aesthetic, playful storytelling, highly detailed, photorealistic, cinematic depth, magazine-quality image, 8K, vertical 9:16 composition. Style: Pixar-meets-high-fashion editorial photography, premium advertisement campaign, joyful and energetic mood. Negative Prompt: blurry, low resolution, extra fingers, extra limbs, distorted face, bad anatomy, duplicate person, cartoon skin, watermark, text, logo, messy composition, deformed hands, cropped subject, oversaturated colors, plastic texture, poorly drawn doodle.

We'll be in Seoul for ICML presenting "Interpreting Physics in Video World Models" at the main conference and mech interp workshop this week! 🌟 Main Conference - Thursday, July 9, 10:30-12:15 pm KST (Hall A 3406) 🌟 Mech Interp Workshop - Friday, July 10, 2-3 pm KST (Board 120) Stop by if you'd like to discuss interpretability for world models, physical reasoning, and scientific simulation!
Today we release a new paper from Meta @AIatMeta: "Interpreting Physics in Video World Models," one of the first interpretability studies of video encoders. V-JEPA 2 shows rich, counterintuitive behaviors, including brain-like population codes and high-dimensional steering.

Silicon Valley pundits love to preach the 80-hour work week; or what is it in China now, the 9-9-6 schedule. They tell you that building the future of AI, robotics, or a venture-backed startup requires constant, grinding hustle. They’re wrong. For a weekend read, I'm staring at "Rest: Why you get more done when you work less" by @AlexSoojun8374 Alex Soojung-Kim Pang. I had bought it last year and it finally rose to the top of the queue. Yet, it seems to be giving words to practices I've long espoused. I'm a "work hard everyday" kind of person, but I'm also a rest, create, expand type of person. One thing really from the beginning of the book jumped out at me. In the foreword, @ariannahuff Arianna Huffington points to a concept that completely refutes the tech-bro narrative: "Layer Work and Rest." The premise is simple but profound: supercreative people alternate periods of intensive work with periods of deliberate rest. She writes, and I'm paraphrasing hre: When you intentionally step away from a grueling technical problem, you aren't quitting. You are actually encouraging your subconscious mind into taking over. By giving yourself time and space immediately after focused effort, you allow your brain to discover the elegant solutions that eluded your conscious grasp. And I think that is actually layered into different temporal hierarchies: a given day, a given week, a given season. In STEM, we often treat humans like silicon processors that just need to be overclocked. But building responsible, impactful technology requires depth and clarity, not just raw compute. Deliberate rest isn't laziness. It’s the ultimate cheat code for bringing real value.

It’s been a trip back to Toronto filled with joy, seeing my kids’ graduations, then the heartache losing my father-in-law. He left us at 89. It was a great run: 3 kids and 8 grandkids. Please consider donating to your local Parkinson’s charity. (Pic of him sailing the world as a ship mechanic.)
