Abstract

fetched live from OpenAlex

Twitter is a popular social network that carries information in short messages. A user's tweets can contain information that is similar to another user's tweets. In this research, we aim to provide stochastic tweets that can be used for testing recommender systems with large data. For this reason, we used term frequency and inverse document frequency (tf-idf) to analyze users' aggregated tweets. The empirical results show Weibull distribution fits the model of tf-idf of the words in users' tweets. Then Weibull distribution is used to generate stochastic data for users' tweets. A simulation of a recommender system was also conducted to test classification of users based on stochastic tweets. The recommender system uses collaborative filtering to find similarity between users. The simulation used k-means clustering to verify the similarity of the stochastic data versus real 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.
