Spatial pooling strategies used in recent Image Quality Assessment (IQA) algorithms have generally been that of simply averaging the values of the obtained scores across the image. Given that certain regions in an image are perceptually more important than others, it is not unreasonable to suspect that gains can be achieved by using an appropriate pooling strategy. In this paper, we explore two...

Motivation: Rapid methods for protein structure search enable biological discoveries based on flexibly defined structural similarity, unleashing the power of the ever greater number of solved protein structures. Projection methods show promise for the development of fast structural database search solutions. Projection methods map a structure to a point in a high-dimensional space and compare t...

This paper introduces a method for the organization of recorded music according to structural similarity. It uses the Normalized Compression Distance (NCD) to measure the pairwise similarity between songs, represented using beat-synchronous self-similarity matrices. The approach is evaluated on its ability to cluster a collection into groups of performances of the same musical work. Tests are a...

We construct metrics from the geodesics of the Structural Similarity index, an image quality assessment measure. An analytical solution is given for the simple case of zero stability constants, and the general solution involving the numerical solution of a nonlinear equation is also found. © 2012 Elsevier Ltd.

Models of analog retrieval require a computationally cheap method of estimating similarity between a probe and the candidates in a large pool of memory items. The vector dot-product operation would be ideal for this purpose if it were possible to encode complex structures as vector representations in such a way that the superficial similarity of vector representations reflected underlying struc...

Children’s difficulties with headed object A’-dependencies have been attributed, on the one hand, to the intervention of a structurally similar element (the subject) in the interpretive chain formed by the moved object with the gap, and on the other, to the incremental processing of these constructions. This study brings new evidence to show that structural similarity as a source of difficulty ...

Measurement of similarity is a critical work for many applications such as text analysis, link prediction and recommendation. However, existing work stresses on content and rarely involves structural features. Even fewer methods are applicable for heterogeneous network, which is prevalent in the real world, such as bibliographic information network. To address this problem, we propose a new mea...

We propose a new retrieval system based on musical structure using symbolic structural queries. The aim is to compare musical form in audio files without extracting explicitly the underlying audio structure. From a given or arbitrary segmentation, an audio file is segmented. Irrespective of the audio feature choice, we then compute a selfsimilarity matrix whose coefficients correspond to the es...

Dual and triple activity-difference (DAD/TAD) maps are twoand threedimensional representations of the pairwise activity differences of compound data sets, respectively [1]. These maps are valuable tools for the systematic characterization of structure-activity relationships (SAR) of compounds data sets screened against two or three targets [2]. Adding pairwise structural similarity information ...

Most commonly, case-based reasoning is applied in domains where attribute value representations of cases are su cient to represent the features relevant to support classi cation, diagnosis or design tasks. Distance functions like the Hamming-distance or their transformation into similarity functions are applied to retrieve past cases to be used to generate the solution of an actual problem. Oft...
