Abstract

fetched live from OpenAlex

Let T be a two-dimensional table with each cell weighted by a nonzero positive number. A StreamTable visualization of T represents the columns as non-overlapping vertical streams and the rows as horizontal bands such that the intersection between a stream and a band is a rectangle with area equal to the weight of the corresponding cell. To avoid large wiggle of the streams, it is desirable to keep the consecutive cells in a stream to be adjacent. The difference between the area of the bounding box containing the StreamTable and the sum of the weights of T is referred to as the excess area. We attempt to optimize various StreamTable aesthetics (e.g., minimizing excess area, or maximizing cell adjacencies in streams). * If the row permutation is fixed and the row heights are given, then we give an O(rc)-time algorithm to optimize these aesthetics, where r and c are the number of rows and columns, respectively. * If the row permutation is fixed but the row heights can be chosen, then we discuss a technique to compute a StreamTable with small area and required cell adjacencies by solving a quadratically- constrained quadratic program, followed by iterative improvements. If the row heights are restricted to be integers, then we prove the problem to be NP-hard. * If the row permutations can be chosen, then we show that it is NP-hard to find a row permutation that optimizes the area or adjacency aesthetics.

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.
