Abstract

fetched live from OpenAlex

We introduce SelfTalk, a novel declarative language that allows users to query and understand the status of a large scale system. SelfTalk is sufficiently expressive to encode an administrator's high level hypotheses/expectations about normal system behavior, such as, "I expect that the throughputs across all system components are linearly correlated". SelfTalk works in conjunction with Dena, a runtime support system designed to help system administrators detect the root cause of system misbehavior quickly and accurately. Given a user hypothesis, Dena instantiates and validates it using actual monitored data within specific system contexts. We evaluate Dena by posing several hypotheses about system behavior and querying Dena to diagnose anomalies in a virtual storage system. We find that Dena can automatically validate the system performance based on the user hypotheses and also accurately diagnose system misbehavior.

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.
