Abstract

fetched live from OpenAlex

The developments in communication, sensor and computing technologies are generating information at increasing rates and the nature of the data is becoming highly heterogeneous. Accordingly, the objects under study are described by collections of variables of very different kinds (e.g. numeric, non-numeric, images, signals, videos, documents, etc.) with different degrees of imprecision and incompleteness. Many data mining and machine learning methods do not handle heterogeneity well, requiring variables of the same type, information completeness (or imputation), also assuming no imprecision. Extreme learning machines (ELM) are very interesting computational algorithms because of their structural simplicity, their good performance and their speed. Accordingly, extending their scope by making them capable of processing heterogeneous information may increase their attractiveness as a modeling tool for addressing complex problems. ELMs are discussed in the context of heterogeneous data and approaches to build ELMs capable of performing classification and regression tasks in such cases are presented. Their performance is illustrated with real world examples of classification and regression involving heterogeneous information with scalar data described by nominal, ordinal, interval, ratio, and fuzzy variables as well as with entire empirical probability distributions as predictor variables.

Full frame distilled prediction

Teacher imitation

Not 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.
