Query-by-Example On-Device Keyword Spotting [PDF]
2019 IEEE Automatic Speech Recognition and Understanding Workshop (ASRU), 2019 A keyword spotting (KWS) system determines the existence of, usually predefined, keyword in a continuous speech stream. This paper presents a query-by-example on-device KWS system which is user-specific. The proposed system consists of two main steps: query enrollment and testing.

Separations in Query Complexity Based on Pointer Functions [PDF]
, 2015 In 1986, Saks and Wigderson conjectured that the largest separation between deterministic and zero-error randomized query complexity for a total boolean function is given by the function $f$ on $n=2^k$ bits defined by a complete binary tree of NAND gates

EURASIP Journal on Audio, Speech, and Music Processing, 2019 The huge amount of information stored in audio and video repositories makes search on speech (SoS) a priority area nowadays. Within SoS, Query-by-Example Spoken Term Detection (QbE STD) aims to retrieve data from a speech repository given a spoken query.

Performance of Graph and Relational Databases in Complex Queries
Applied Sciences, 2022 In developing NoSQL databases, a major motivation is to achieve better efficient query performance compared with relational databases. The graph database is a NoSQL paradigm where navigation is based on links instead of joining tables.

Bridging the Gap: Query by Semantic Example [PDF]
IEEE Transactions on Multimedia, 2007 A combination of query-by-visual-example (QBVE) and semantic retrieval (SR), denoted as query-by-semantic-example (QBSE), is proposed. Images are labeled with respect to a vocabulary of visual concepts, as is usual in SR. Each image is then represented by a vector, referred to as a semantic multinomial, of posterior concept probabilities.

Text-Image Matching for Cross-Modal Remote Sensing Image Retrieval via Graph Neural Network
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 The rapid development of remote sensing (RS) technology has produced massive images, which makes it difficult to obtain interpretation results by manual screening. Therefore, researchers began to develop automatic retrieval method of RS images. In recent

A Query Language for Data Access in Ubiquitous Environments
CLEI Electronic Journal, 2018 Recent progress in ubiquitous computing technology is allowing development of new and so- phisticated applications that are now able to store very large data on the mobile device itself, besides access data stored remotely. Thus emerges the need to query

gmos: Rapid Detection of Genome Mosaicism over Short Evolutionary Distances. [PDF]
PLoS ONE, 2016 Prokaryotic and viral genomes are often altered by recombination and horizontal gene transfer. The existing methods for detecting recombination are primarily aimed at viral genomes or sets of loci, since the expensive computation of underlying ...
