Ranking and necessity: the Fusional Reduction Algorithm

Ranking and Necessity: The Fusional Reduction Algorithm

Understanding a linguistic theory within OT requires an exact characterization of the ranking conditions necessitated by data. These conditions determine the formal shape of the grammar while providing the crucial link between the data and its interpretation. We introduce an algorithm (‘Fusional Reduction’, FRed) which calculates the necessary and sufficient ranking conditions inherent in any c...

Reliability adjustment: a necessity for trauma center ranking and benchmarking.

BACKGROUND Currently, trauma center quality benchmarking is based on risk adjusted observed-expected (O/E) mortality ratios. However, failure to account for number of patients has been recently shown to produce unreliable mortality estimates, especially for low-volume centers. This study explores the effect of reliability adjustment (RA), a statistical technique developed to eliminate bias intr...

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

Dimension Reduction for Object Ranking

Ordered lists of objects are widely used as representational forms. Such ordered objects include Web search results and best-seller lists. Techniques for processing such ordinal data are being developed, particularly methods for an object ranking task: i.e., learning functions used to sort objects from sample orders. In this article, we propose two dimension reduction methods specifically desig...
