Abstract

fetched live from OpenAlex

To allow visitors to flee the Louvre the first time after a terrorist attack on the Louvre, we have built such a model. We looked up some data about the Louvre, then analyzed the types of terrorist attacks, and developed a more flexible evacuation model. We first put together the closer exits and refer to them as an exit group. Each exit group is accompanied by a region in which visitors must evacuate from that exit group. Each region has a planned escape route, and staff in the region will lead visitors to evacuate. The division of each region is determined by factors such as the traffic capacity of the exit group and the pavilion in which it is located. We calculate the area of each region accordingly. After each floor block, we get some areas where each region has its own escape route. We come up with an optional path through the ant colony algorithm. Visitors from each region can simply follow the arrangements of the staff on each floor to evacuate quickly. In order to verify the model, we fit the formula of escape speed according to the data of many aspects. Through the formula, we calculated the time of the tourist escape more accurately, which is a better simulation of the real scene of the tourist escape. Also, we have made a lot of recommendations for the Louvre in response to different types of terrorist attacks. We also discussed where terrorist at tacks took place and considered them from multiple angles. In order to enable rescue workers to quickly enter the scene, we have also proposed a number of improvement measures.

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.
