Academic faculty comparing their research output 😅

I use Jekyll to build my academic site. Maintenance used to be painful. With Codex, it became painless.

What did Yann LeCun see? 🤔

Paper rejected from #CVPR2025, paper ready for #ICCV2025 💪

At one point, MIT thought neural networks weren’t worth teaching in intro #AI. Trends change. Fundamentals don’t.

AI won’t just change how we assess students. It can also transform how we teach them. Interactive visualizations can make abstract concepts more intuitive and engaging. Check out this epipolar geometry visualization created with Codex. Link to interactive webpage in thread.

#KostasKeynoteLessons: Curious about the "Keynote magic" behind my slides? I’m releasing the full Keynote source file for my recent Gaussian Splatting lecture, all 10 GIGAbytes of it! Grab the files in the thread and feel free to remix.

Back to the lecture prep grind. VERY early version of my lecture on Policy Gradients. With #computervision and #robotics research appearing to converge, at least based on #CVPR2026 and my European tour conversations, it feels like good timing 😉

Fun with 3D Gaussians using After Effects. Perhaps part of a future lecture 😉

Nearest neighbour for the win 💪

My publicity chair retirement didn't last long 😉 I just joined the #ECCV2026 European Conference on Computer Vision #ECCV2026 publicity team 😅 New mask, same task. We are looking to grow our team and coverage, including adding a social media account in China. Stay tuned.

Sometimes we need a reality check 😉
