Optimizing Multistage Discriminative Dictionaries for Blind Image Quality Assessment

IEEE transactions on multimedia, 2018
State-of-the-art algorithms for blind image quality assessment (BIQA) typically have two categories. The first category approaches extract natural scene statistics (NSS) as features based on the statistical regularity of natural images.

Deterministic Dictionaries

Journal of Algorithms, 2001
Summary: It is shown that a static dictionary that offers constant-time access to \(n\) elements with \(w\)-bit keys and occupies \(O(n)\) words of memory can be constructed deterministically in \(O(n\log n)\) time on a unit-cost RAM with word length \(w\) and a standard instruction set including multiplication.

Dictionaries for Sparse Representation Modeling

Proceedings of the IEEE, 2010
Sparse and redundant representation modeling of data assumes an ability to describe signals as linear combinations of a few atoms from a pre-specified dictionary.

The big two dictionaries: Capturing agency and communion in natural language

European Journal of Social Psychology, 2019
Four studies developed and validated two dictionaries to capture agentic and communal expressions in natural language. Their development followed the Linguistic Inquiry and Word Count (LIWC) approach (Study 1) and we tested their validity with frequency ...

Johnson's 'Dictionary' and Dictionary Johnson

The Yearbook of English Studies, 1998
Popular ideas about the authorship of dictionaries have a curious double life. On the one hand, any and all dictionaries of a given language are likely to be thought of under the impersonal rubric of'the dictionary': we have often been told and often told others to 'look it up in the dictionary'.

Dictionaries and the Dictionary

2000
Abstract It is traditional to start with definitions, and this is particularly appropriate in the circumstances, since the main object of lexicography is to define words and terms. Of course, the central notion to be defined is the notion of ‘dictionary’.

Dictionary management

2017
In management theories we find different descriptions of project planning, but the following steps occur in most management plans: target, concept, time plan with milestones and a deadline, project management and the delegation of tasks. These abstract steps are in practice applied very differently in different projects.

Dictionary types and dictionary users

2008
Abstract This chapter sets dictionary writing in its context. It looks at how the dictionary comes about in the first place and how dictionaries may be classified. The dictionary user is shown to play a central role in the planning process, and we illustrate the ways in which editorial decisions are influenced by our understanding of the
