Having not written anything about my #tricycle project in months, I've now written two posts in two days. Here's the first:

Rethinking the tricycle drive train

Rethinking the tricycle drive train
I've been rereading my posts on design of a tricycle, and especially this one; and I've been looking again at this picture, of Seventy Seven's removable front subframe which carries its front wheel, steering, and transmission systems; and I've been thinking. This will be a short post documenting my thoughts.

FlowDrive: moderated flow matching with data balancing for trajectory planning
Learning-based planners are sensitive to the long-tailed distribution of driving data. Common maneuvers dominate datasets, while dangerous or rare scenarios are sparse. This imbalance can bias models toward the frequent cases and degrade performance on critical scenarios. To tackle this problem, we compare balancing strategies for sampling training data and find reweighting by trajectory pattern an effective approach. We then present FlowDrive, a flow-matching trajectory planner that learns a c…

Die „Tragik der Allmende“ besteht insbesondere bei lokalem Gemeinbesitz¹ vor allem darin, daß Einzelne keinen Gewinn mit etwas machen können, was allen gehört – und das ist aus Sicht des Kapitalismus tragisch.²

JointDiff: Bridging Continuous and Discrete in Multi-Agent Trajectory Generation
Generative models often treat continuous data and discrete events as separate processes, creating a gap in modeling complex systems where they interact synchronously. To bridge this gap, we introduce JointDiff, a novel diffusion framework designed to unify these two processes by simultaneously generating continuous spatio-temporal data and synchronous discrete events. We demonstrate its efficacy in the sports domain by simultaneously modeling multi-agent trajectories and key possession events. …

Positive traces on certain $\operatorname{SL}(2)$ Coulomb branches
For a noncommutative algebra $A$ and an antilinear automorphism $ρ$ of $A$ there is a notion of a positive trace. Positive traces appear in study of supersymmetric gauge theories. We classify positive traces on $A$ in two cases. The first case is when $A$ is a quantization of a Kleinian singularity of type $D$, with certain restriction on the quantization parameter. The second case is when $A=K^{\operatorname{SL}(2,\mathbb{C}[[t]])\rtimes \mathbb{C}_q^{\times}}(\operatorname{Gr}_{\operatorname…
