A watershed desk can feed an LLM either a flat list of sensor IDs or a short description of which sensors share a parent tributary — a graph-derived feature. They want to know which input helps a downstream summary. How should they compare those inputs?
Select an answer to reveal the explanation.
Short Explanation
Flat sensor IDs versus a short parent-tributary description. Hold the model and the gold summaries constant and treat that graph-derived feature as the input. Do not turn the trial into a vector-index job, a CUDA printout, or an image-fusion stack.
Full Explanation
Graph-derived features can be an experimental input to an LLM task: same model, same gold summaries, only the prompt payload changes. A short parent-tributary description versus a flat ID list is that factor. Building a retrieval index is a later data-prep concern and is not required to run this comparison. Kernels and multimodal image fusion are the wrong harness.
