Linear Attention Architectures: Mechanisms, Trade-offs, and Cross-Layer Routing
Tommaso Cerruti, Tim Rieder, George Rowlands +2
Self-attention lets each token retrieve information from the full context, but its quadratic cost in sequence length limits training and inference at long context. This paper prese…

SimAB: Simulating A/B Tests with Persona-Conditioned AI Agents for Rapid Design Evaluation
Tim Rieder, Marian Schneider, Mario Truss +6
A/B testing is a standard method for validating design decisions, yet its reliance on real user traffic limits iteration speed and makes certain experiments impractical. We present…

Random-Shift Revisited: Tight Approximations for Tree Embeddings and L1-Oblivious Routings
Rasmus Kyng, Maximilian Probst Gutenberg, Tim Rieder
We present a new and surprisingly simple analysis of random-shift decompositions -- originally proposed by Miller, Peng, and Xu [SPAA'13]: We show that decompositions for exponenti…
