Abstract

fetched live from OpenAlex

In indoor positioning applications, UWB technology can achieve centimeter-level positioning accuracy, and has good resistance to multipath interference and weakness, as well as strong penetration. However, due to the complex and changeable indoor environment, UWB communication signals are easily blocked. Although UWB technology has penetration capability, it still produces errors. When there is strong interference, fluctuations of will occur, and indoor positioning cannot be basically completed, or even serious accidents will occur. Therefore, the problem of ultra-wideband (UWB) precise location under signal interference becomes an urgent problem to be solved. An algorithm is established to find the correct distance between the abnormal data processed by the minimum sum of absolute distance differences and normal data. Optimal target optimization A model based on shark optimization and UWB localization based on least square method are used to establish a comparison model, using shark optimization model can better calculate the exact location of Tag point.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
