Abstract

fetched live from OpenAlex

While originally proposed to provide fault-tolerance and scalability for data analysis queries on unstructured data over massive clusters, MapReduce systems today are being used for analysis of rich combinations of unstructured, semi-structured and structured data. To achieve performance on these new workloads, MapReduce systems (and the distributed file systems on which they are built) can no longer rely on static data placement strategies. In this thesis, we propose new physical data independence and adaptive data tuning solutions that can greatly improve the performance of analysis queries in systems where workloads are not static and where workloads may include complex queries with overlapping or related computations (subqueries). While profiting from the work on physical data independence in relational systems, we propose novel strategies that recognize the central role of data partitioning (and co-partitioning) in shared-nothing distributed file systems.

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.
