Slice-Based Online Convolutional Dictionary Learning
IEEE Transactions on Cybernetics, 2021Convolutional dictionary learning (CDL) aims to learn a structured and shift-invariant dictionary to decompose signals into sparse representations. While yielding superior results compared to traditional sparse coding methods on various signal and image processing tasks, most CDL methods have difficulties handling large data, because they have to ...

An online algorithm for distributed dictionary learning
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015This paper proposes a novel algorithm for online distributed dictionary learning, where a set of nodes is requested to collectively estimate a common dictionary via sequentially received data vectors. At each time instance, in which a new datum becomes available, the sparse representation of the data with respect to the estimated dictionary is computed

Automated dictionary discovery for the online marketplace
Proceedings of the 2012 iConference, 2012Shopping online has become a prolific activity as the number of online vendors and consumers continue to rise each year. In 2009, almost $15 billion in goods and services were ordered online by Canadians [1]. About 53% of these consumers 'window shop' by doing product research before actually making a purchase.

Online kernel dictionary learning on a budget
2016 50th Asilomar Conference on Signals, Systems and Computers, 2016Online kernel-based dictionary learning (DL) algorithms are considered, which perform DL on training data lifted to a high-dimensional feature space via a nonlinear mapping. Compared to batch versions, online algorithms require low computational complexity, essential for processing the Big Data, based on the stochastic gradient descent method. However,

Dynamic Dictionary Matching in the Online Model
2019In the classic dictionary matching problem, the input is a dictionary of patterns \(\mathcal {D}=\{P_1,P_2,\ldots ,P_k\}\) and a text T, and the goal is to report all the occurrences in T of every pattern from \(\mathcal {D}\). In the dynamic version of the dictionary matching problem, patterns may be either added or removed from \(\mathcal {D}\).

2014
Until now, there has been little research into the use of online dictionaries despite expanding markets: both academic and commercial lexicography increasingly focus on online products while sales figures for printed dictionaries decline. This created a demand for reliable empirical information on how online dictionaries are actually used and how they ...

Teaching Dictionary Skills through Online Bilingual Dictionaries
2022This module, aimed at helping both English as a Foreign Language (EFL) teachers and their students, is the result of a qualitative, applied, transversal and constructivist research conducted with Open Lingua teachers. One of the objectives of said research was to establish the factors that favored and hindered the curriculum integration of open access ...

Online dictionaries of English
2010In this paper I present an overview of the spectrum of available online English language dictionaries, and then offer some general comments on a few selected key issues. Given the current explosion of web content, it is quite pointless to try to list every single dictionary available.

Online emotional facial expression dictionary
Proceedings of the 15th International Conference on Computer Systems and Technologies, 2014Facial expressions play an important role in human communication. But there is a lot of disagreement about the semantic interpretation. In this paper we present an online facial expression dictionary. Users can upload a facial expression which will be interpreted automatically.

Online Dictionary Matching with Variable-Length Gaps
2011The string-matching problem with wildcards is considered in the context of online matching of multiple patterns. Our patterns are strings of characters in the input alphabet and of variable-length gaps, where the width of a gap may vary between two integer bounds or from an integer lower bound to infinity.
