Did I say GTSAM 4.3 is available? If using @gtsam4 I recommend switching to the latest version. We'll keep develop on a 4.3 version for now to quickly react to any breaking changes - but really only expect better performance :-) gtsam.org/

Can Jev specify graphical models for us?

One of the issues I discussed with students in class today is the ethical component: the Bayes nets will inherit whatever biases Jed has internalized from its training data.

🎉 Excited to share our recent work on deformable object manipulation, 𝗣𝗵𝘆𝘀𝗖𝗼𝗥𝗲, accepted to 𝗖𝗼𝗥𝗟 𝟮𝟬𝟮𝟲. Congrats to @hcy1n @ShuohanT! 𝗖𝗼𝗱𝗲 & 𝗗𝗮𝘁𝗮: lunarlab-gatech.github.io/Ph… #CoRL2026 #RobotLearning #DeformableObjects

PhysCoRe: Physics-Corrected Residual World Models for Material-Aware Deformable Dynamics

A physics-corrected residual world model that infers per-particle material from visual observations and corrects a differentiable MPM simulator. CoRL 2026.

Excited to share our #CoRL2026 work PhysCoRe: a physics-corrected world model for deformable objects! We couple a physics-based simulator with two feed-forward modules: one infers material from vision, the other corrects its internal dynamics. Check: lunarlab-gatech.github.io/Ph…

Some very cool work from @VarunGiridhar3 et al in @animesh_garg’s group - @GTrobotics FTW!

You fine-tune a robot foundation model on a hard task. It gets 25%. Now what? Introducing Q-Planning, a learning-based harness that lets large black-box robot policies recursively self-improve. On a hard fine-grained task: 25% → 80% in 100 robot attempts (~30 mins), no extra human data. q-planning.github.io/ 1/n 🧵

GTSAM is going GPU! 🚀 Ruogu Li has built an impressive new experimental CUDA backend for nonlinear factor-graph optimization in GTSAM, just in time for the 4.3 release next week.

Exciting to see how the community puts @gtsam4 to work! In a guest post, Jash Shah explores an application of factor graphs to 3D Gaussian Splatting, bringing neural rendering together with pose graphs, loop closures, robust noise models, and iSAM2. gtsam.org/2026/08/04/gaussia… #GTSAM #SLAM #3DGS
