Many imaging techniques for multimodal retinal images are developing in the recent...

In this paper we consider the problem of finding a vector that can be written as a nonnegative, integer and linear combination of given 0-1 vectors, the generators, such that the l1-distance between this vector and a given target vector is minimized. We prove that this closest vector problem is NP-hard to approximate within an additive error of (ln 2− ǫ)d ≈ (0, 693 − ǫ) d for all ǫ > 0 where d ...

Background: One long-standing issue in Estimation by Analogy (EBA) is finding closest analogies. Prior studies revealed that existing similarity measures are easily influenced by extreme values and irrelevant features. Aims: Instead of identifying closest projects based on the aggregated similarity degrees, we propose to use Ranked Voting Methods that rank projects per feature and then aggregat...
