Query-by-Example Search with Discriminative Neural Acoustic Word Embeddings [PDF]
Interspeech, 2017 Query-by-example search often uses dynamic time warping (DTW) for comparing queries and proposed matching segments. Recent work has shown that comparing speech segments by representing them as fixed-dimensional vectors --- acoustic word embeddings ...

Query by Example in Remote Sensing Image Archive Using Enhanced Deep Support Vector Data Description
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 This article studies remote sensing image retrieval using kernel-based support vector data description (SVDD). We exploit deep SVDD, which is a well-known method for one-class classification to recover the most relevant samples from the archive.

CNN Based Query by Example Spoken Term Detection
Interspeech, 2018 In this work, we address the problem of query by example spoken term detection (QbE-STD) in zero-resource scenario. State of the art solutions usually rely on dynamic time warping (DTW) based template matching.

Partial-sum queries in OLAP data cubes using covering codes [PDF]
, 1997 A partial-sum query obtains the summation over a set of specified cells of a data cube. We establish a connection between the covering problem in the theory of error-correcting codes and the partial-sum problem and use this connection to devise ...

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.
