Abstract

fetched live from OpenAlex

The purpose of this study is to compare a series of well-known statistical machine learning techniques that classify online social network (OSN) Twitter users based on their socioeconomic status (upper/middle/lower). In the experiments, five classification algorithms are employed for the classification task. Logistic Regression, Support Vector Machine (SVM), Naïve Bayes (NB), k-Nearest Neighbors, and Decision Tree are applied on high-dimensional data set extracted from the users’ platform-based and profile-based behavior on Twitter. These algorithms are theoretically investigated and experimentally evaluated in terms of four performance measures: accuracy, precision, recall and, AUC. Ensemble methods are employed to improve the performance of the aforementioned algorithms. MANOVA is employed to examine if their performance measures are significantly different. ANOVA is used to analyze the differences of the classifiers for each performance measure. The analyses indicate a significant difference among these algorithms; both SVM and NB achieve good performance on our high-dimensional OSN data.

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.

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.
