Abstract

fetched live from OpenAlex

Autonomic systems are motivated by the increased scale, complexity and cost of managing the current information infrastructure. Database configuration advisors are a very successful class of autonomic tools (they suggest desirable indexes, materialized views, and so on). Giving advice on configurations is a challenging task, yet the rewards on system responsiveness and performance can be huge. In this thesis we describe an iterative framework to provide on-going recommendations. We present algorithms that re-assess recommendations every step of the way until the DBMS reaches a satisfactory level of performance. Our proposal should be contrasted with the current approach of applying all of the recommender suggestions in one big batch. The proposed iterative framework allows the user to control the process of implementing new physical structures while observing the improvement in performance.

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.
