Similarity Search Using Multiple Examples in MARS
Unlike traditional database management systems, in multimedia databases that support content-based retrieval over multimedia objects, it is di cult for users to express their exact information need directly in the form of a precise query. A typical interface supported by content-based retrieval systems allows users to express their query in the form of examples of objects similar to the ones th...
متن کاملSimilarity Search in Arbitrary Subspaces Under Lp-Norm
Similarity search has been widely used in many applications such as information retrieval, image data analysis, and time-series matching. Specifically, a similarity query retrieves all data objects in a data set that are similar to a given query object. Previous work on similarity search usually consider the search problem in the full space. In this paper, however, we propose a novel problem, s...
متن کاملDetermining appropriate weight for criteria in multi criteria group decision making problems using an Lp model and similarity measure
Decision matrix in group decision making problems depends on a lot of criteria. It is essential to know the necessity ofweight or coefficient of each criterion. Accurate and precise selection of weight will help to achieve the intended goal.The aim of this article is to introduce a linear programming model for recognizing the importance of each criterion inmulti criteria group decision making w...
متن کاملOn Projection Based Operators in lp Space for Exact Similarity Search
We investigate exact indexing for high dimensional lp norms based on the 1-Lipschitz property and projection operators. The orthogonal projection that satisfies the 1-Lipschitz property for the lp norm is described. The adaptive projection defined by the first principal component is introduced.
متن کاملOn the Suitability of Lp-norms for Creating and Preventing Adversarial Examples
Much research effort has been devoted to better understanding adversarial examples, which are specially crafted inputs to machine-learning models that are perceptually similar to benign inputs, but are classified differently (i.e., misclassified). Both algorithms that create adversarial examples and strategies for defending against them typically use Lp-norms to measure the perceptual similarit...
