As part of the MediaEval 2013 benchmark evaluation campaign, the objective of the Spoken Web Search (SWS) task was to perform Query-by-Example Spoken Term Detection (QbE-STD), using spoken queries to retrieve matching segments in a set of audio files. As in previous editions, the SWS 2013 evaluation focused on the development of technology specifically designed to perform speech search in a low...

Many interesting pieces of music violate established structures or rules of their genre on purpose. These songs can be very atypical in their interior structure and their different parts might actually allude to entirely different other songs or genres. We present a query-by-example-based user interface that shows songs related to the one currently playing. This relation is not based on overall...

We report the results of an experiment designed to shed light on beliefs off equilibrium paths. The experiment implements an incomplete information club game. A unique outcome results in all perfect Bayesian equilibria, but beliefs and actions off the equilibrium path are unconstrained under all concepts except extensive form rationalizability (EFR) and logit equilibrium. 90% of subject’s decis...

This paper describes a music remixing interface, called Instrument Equalizer, that allows users to control the volume of each instrument part within existing audio recordings in real time. Although query-by-example retrieval systems need a user to prepare favorite examples (songs) in general, our interface gives a user to generate examples from existing ones by cutting or boosting some instrume...

This paper describes Probabilistic Bias Evaluation (PBE), a method for evaluating learning biases formally analyzing the tradeoff between the expected accuracy and complexity of alternative biases. Intelligent agents must filter out irrelevant aspects of the environment, in order to minimize the costs of learning. In PBE, probabilistic background knowledge about relevance is used to compute exp...

We present a novel method for searching for unknown music. RhythMiXearch is a music search system we developed that can accept two music inputs and mix those inputs to search for music that could reasonably be a result of the mixture. This approach expands the ability of Query-by-Example and allows greater flexibility for users in finding unknown music. Each music piece stored by our system is ...

We present a novel framework for intelligent search and retrieval by image content composition. Very different from the existing Query-by-Example paradigm, logical queries are expressed using categories of similar regions without any starting example region. The set of region category representatives constitutes the “photometric region thesaurus” of the image database. Logical composition of re...

We present a visualization oriented data mining tool designed for biomedical images with focus objects. The main functions of the tool are accessible via two interfaces: Query by Example and Query by Features. Each interface has visual feedback functions associated with it. The query-by-example interface allows the user to do similarity search using multiple image features. The visual feedback ...

This paper describes an effective unsupervised method for query-by-example speaker retrieval. We suppose that only one speaker is in each audio file or in audio segment. The audio data are modeled using a common universal codebook. The codebook is based on bag-of-frames (BOF). The features corresponding to the audio frames are extracted from all audio files. These features are grouped into clus...
