Abstract

fetched live from OpenAlex

Human visual system can recognize incomplete contours and objects easily. However, these kind of recognition tasks are challenging in computer and robot vision. This paper demonstrates how combination of genetic algorithm and morphology operations can be used to generate an image processing procedure for recognition of subjective objects (e.g. incomplete objects). For this purpose, the approach receives the subjective object and the corresponding user-prepared gold sample (physical object which reflects the user’s expectations). After carrying out the training or optimization phase, the optimal procedure is generated and ready to be applied on new subjective objects (the same object but with different incomplete forms, sizes, etc.). As the most important feature of this approach, it does not need any prior knowledge; the training takes place based on one gold sample. This desirable characteristic reduces the level of dependency on expert participation which is usually an obstacle for full automation in most applications. The approach architecture and the employed methodologies are explained in detail. The performance of the approach has been evaluated by several well-prepared experiments.

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.
