    Resolution limits for process comparison from event data

    Antony R. Lee, Peter Tiňo, Iain B. Styles

    cs.DB · cs.LG · stat.ML

    One hospital runs bloods and imaging at the same time. Another runs them one after the other, in either order, equally often. Knowing which actually happened, and how it is recorded in data, is critical for all operational managers. In process mining, the standard approach is to construct an event log, and attempt to discover concurrent and sequential processes in a data-driven way. We show this standard approach, built on the stochastic...

    A Functional Pilot for Certified Freshness-Aware Semantic--Spatial Range Retrieval

    Taimoor Ahmad

    cs.DB · cs.AI

    Geographic applications need every object inside a radius that satisfies a semantic threshold, yet embedding indexes return approximate top-ranked lists and may omit qualifying records silently. We present FRESH-GEORANGE, a semantic- spatial range design that separates source-watermark freshness from optional record age. Geographic cells and semantic mi- croblocks provide admissible pruning bounds; a graph proposes verification order but...
