Research Scholar, Computer Science and Engineering Department, Lingaya’s University, Faridabad Associate Professor, Computer Science and Engineering Department, Lingaya’s University, Faridabad [email protected], [email protected] ABSTRACT An ample amount of documents present on web puts the users in state of dilemma. Users get confused about relevance of documents. Relevance means ...

Effects of Feature Normalization on Image Retrieval

Image retrieval algorithms use distances between feature vectors to compute similarities between images. An important step between feature extraction and distance computation is feature normalization. Popular distance measures like the Euclidean distance implicitly assign more weighting to features with large ranges than those with small ranges. This paper describes six normalization methods to...

Formulas of Retrieval Rate in Database Based on Normalization Design

A normalization database is considered as mathematics logical design to avoid redundancies and inconsistencies in the stored data which brought about null data and many relationship tables in the physical database. A retrieval rate is affected directly in running a practical system of the normalization design. We argue in the paper that rate formulas given out retrieval speed via testing the va...

Normalization in Support Vector Machines

This article deals with various aspects of normalization in the context of Support Vector Machines. We consider fist normalization of the vectors in the input space and point out the inherent limitations. A natural extension to the feature space is then represented by the kernel function normalization. A correction of the position of the Optimal Separating Hyperplane is subsequently introduced ...
