Abstract

fetched live from OpenAlex

Based on stochastic property of the transportation system,the function relation between stochastic travel time,the loss,and the flow are studied.A Frequency-domain Spanning Graph(FSG) model for searching multi-objective optimal path of the time-dependent stochastic transportation network is presented,and the corresponding algorithm is designed to deal with the model.Through the mutual transformation of probability function between time-domain and frequency-domain,O-D multi-objective probability change is capable of quantitative analysis.Continuous probability distribution and discrete probability distribution can be dealt with in the model.Experiment with Matlab proves the feasibility and effectiveness of the algorithm.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
