Multi-Dimensional Semantic Map Design and High-Precision Localization for Train Group Control

Group-based train control is expected to break the capacity bottleneck of conventional block-based signaling by operating trains in closely spaced formations, which requires continuous, precise train positioning and semantic maps that encode control-relevant elements such as the...

A Generalizable Framework for Building Executable Domain‐Specific Large Language Models Under Data Scarcity: Demonstration on Semiconductor Technology Computer‐Aided Design Simulation

Scientific and engineering verticals often suffer from data scarcity and strict executability requirements: models must generate not only fluent text but also syntactically valid, tool‐compilable scripts. We present a schema‐first alignment framework for building compact, executa...
