Abstract

fetched live from OpenAlex

Databases have reduced the cost associated with data management by abstracting applications from information processing challenges. There is an increasing need for managing and analyzing data in smaller embedded devices and sensor nodes. Due to resource limitations, these devices typically do not have well-defined data management APIs and standards such as the relational model and SQL. This results in increased complexity and cost. LittleD is a SQL relational database allowing ad-hoc queries on sensor devices. The novel implementation of LittleD adapts to memory and code size restrictions by streamlining query parsing and execution and implementing efficient memory management techniques. Experimental results demonstrate that LittleD executes queries with joins and selections on devices with less than 2 KB memory in a few seconds.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
