Abstract

fetched live from OpenAlex

One major bottleneck in the practical implementation of received signal\nstrength (RSS) based indoor localization systems is the extensive deployment\nefforts required to construct the radio maps through fingerprinting. In this\npaper, we aim to design an indoor localization scheme that can be directly\nemployed without building a full fingerprinted radio map of the indoor\nenvironment. By accumulating the information of localized RSSs, this scheme can\nalso simultaneously construct the radio map with limited calibration. To design\nthis scheme, we employ a source data set that possesses the same spatial\ncorrelation of the RSSs in the indoor environment under study. The knowledge of\nthis data set is then transferred to a limited number of calibration\nfingerprints and one or several RSS observations with unknown locations, in\norder to perform direct localization of these observations using manifold\nalignment. We test two different source data sets, namely a simulated radio\npropagation map and the environments plan coordinates. For moving users, we\nexploit the correlation of their observations to improve the localization\naccuracy. The online testing in two indoor environments shows that the plan\ncoordinates achieve better results than the simulated radio maps, and a\nnegligible degradation with 70-85% reduction in calibration load.\n

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
