Protocol Compression Changes Which Party Pays: Bilateral Cost in Cross-Organization LLM Agent Communication
Janghoon Lee
Agents that talk across organizations exchange long messages billed by the token. A shorter notation therefore looks like a saving that costs nothing but an agreement to use it. Re…
Repair, Not Improvement: Decomposing Constrained Decoding in Tool-Call Abstention
Janghoon Lee
A tool-calling router has to pick the right tool when one applies and decline when none does. Restricting the decoder to a grammar over the tool names is the standard remedy for th…
Most of the LLM Routing Gap Is Task Type
Janghoon Lee
An LLM router picks which model should answer each query. The appeal is that models fail on different questions. Whatever single model is best overall still gets some wrong, and an…
3W Dataset 2.0.0: a realistic and public dataset with rare undesirable real events in oil wells
Ricardo Emanuel Vaz Vargas, Afrânio José de Melo Junior, Celso José Munaro +17
In the oil industry, undesirable events in oil wells can cause economic losses, environmental accidents, and human casualties. Solutions based on Artificial Intelligence and Machin…
Geophysics-informed neural network for model-based seismic inversion using surrogate point spread functions
Marcus Saraiva, Ana Muller, Alexandre Maul
Model-based seismic inversion is a key technique in reservoir characterization, but traditional methods face significant limitations, such as relying on 1D average stationary wavel…
A relax-fix-and-exclude algorithm for an MINLP problem with multilinear interpolations
Bruno Machado Pacheco, Pedro Marcolin Antunes, Eduardo Camponogara +4
This paper introduces a novel algorithm for Mixed-Integer Nonlinear Programming (MINLP) problems with multilinear interpolations of look-up tables. These problems arise when object…
