Pay for Percentile

Pay for Percentile

We propose an incentive pay scheme for educators that links educator compensation to the ranks of their students within appropriately defined comparison sets. Because this scheme employs only ordinal information, it allows education authorities to employ new assessments at each testing date without ever having to equate various assessment forms. Thus, our scheme mitigates incentives for teacher...

Percentile Blobs for Image Similarity

We present a new algorithm called PBSIM for computing image similarity, based upon a novel method of extracting bloblike features from images. In tests on a classification task using a data set of over 1000 images, PBSIM shows significantly higher accuracy than algorithms based upon color histograms, as well as previously reported results for another approach based upon bloblike features.

Fast percentile filtering

Four algorithms for percentile filtering are compared. The ways they can be implemented in hardware and software, their flexibility and their speed are taken into account.

Percentile Finding Algorithm for Multiple Sorted Runs

External sorting is frequently used b>relational database s!-stems for building indexes on tables, ordered retrieval, duplicate elimination, joins, subqueries. grouping, and aggregation; it would be quite beneficial to parallelize this function. Previous parallel external sorting algorithms found in the database literature used a sequential merge as the final stage of the parallel sort. This re...
