Abstract
Procedure Design for Experiments Towards Modeling of the Cutting Force in Excavation of Bulk Media A. Hemami, F. Hassani Pages 111-117 (2003 Proceedings of the 20th ISARC, Eindhoven, Holland, ISBN 978-90-6814-574-8, ISSN 2413-5844) Abstract: The work discussed in this paper concerns automation of excavation or automation of loading particulate media by an excavating machine. Based on the analysis of the process, knowledge of the force of cutting/digging is required for feedback purposes. The lack of a reliable and well established model for the force in question dictates the primary work of the development of such a model. This interaction force is a function of a large number of parameters. Up to 32 parameters have been proposed. In addition to the large number of the parameters an analytical formulation of such a model is less likely possible, as can be seen from the past work. The complexity of the matter, therefore, calls for an empirical formulation, based on the results of experiments that must be carried out. This calls for a huge number of tests. It is important to reduce, as much as possible, the number of experiments to be performed. Also, if the material is categorized in a logical manner, various media can be prepared by mixtures of only a finite number of materials. The objective of the present paper is to define a generic function for the mathematical model and a plan for the tests that must be performed on soil type material. This leads to increased efficiency and helps to reduce duplications and unnecessary work before spending time on experiments. Based on this systematic approach the experiments can be arranged in a logical order, and the results can be later plugged in at their proper places.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
