Abstract

fetched live from OpenAlex

Queries for similarity-based time series data retrieval can be categorized into two types: (1) pattern existence queries, and (2) exact match queries. Pattern existence queries find the time series data with certain patterns while exact match queries search over the time series data by specifying exact values and detailed temporal information. In this paper, we propose multi-scale time series histograms that can be used to answer both types of queries, thus offering users more flexibility. The experimental results show that multi-scale histograms can effectively find the patterns in time series data as well as answer exact match queries, even when the data contain noise, local time shifting, local time scaling, amplitude shifting and amplitude scaling. 1

Full frame distilled prediction

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.
