Data and Knowledge Visualization with Virtual Reality Spaces, Neural Networks and Rough Sets: Application to Geophysical Prospecting
Bibliographic record
Abstract
Visual data mining with virtual reality spaces are used for the representation of data and symbolic knowledge. The approach is illustrated with data from a geophysical prospecting case in which partially defined fuzzy classes are present. In order to understand the structure of both the data and knowledge extracted in the form of production rules, structure-preserving and maximally discriminative virtual spaces are constructed. High quality visual representations can be obtained using Samann and nonlinear discriminant neural networks. Rough set techniques are used for demonstrating the irreducibility of the set of original attributes and for learning the symbolic knowledge. Grid computing techniques are used for constructing sets of virtual reality spaces and for assessing the behavior of some of the neural network parameters controlling the quality of the virtual worlds. The general properties of the symbolic knowledge can be found with greater ease in the virtual reality space whereas both the prediction of unknown objects to the target class, as well as a derivation of a fuzzy membership function from the virtual reality space and the neural network results are obtained.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
