In this paper we report on the ISMIR 2004 Audio Description Contest. We first detail the contest organization, evaluation metrics, data and infrastructure. We then provide the details and results of each contest in turn. Published papers and algorithm source codes are given when originally available. We finally discuss some aspects of these contests and propose ways to organize future, improved...

In this paper we summarize the framework and the results of the fourth edition of the International Symbol Recognition Contest, organized in the context of GREC’11. The contest follows the series started at the GREC’03 workshop and it is the first time that, in addition to recognition of isolated symbols, the contest includes the evaluation of symbol spotting. In this report we describe the eva...

In this paper, a group contest is analyzed, where the groups are allowed to determine their sharing rules either sequentially or simultaneously. It is found that in case the more numerous group determines its sharing rule prior to the smaller group, rent dissipation in the group contest is higher than in an individual contest. However, if the order of moves is endogenized, the smaller group wil...

Simulation system is charged with the strategy validation and dual team meets, and as the 2dimensional simulation platform for underwater robotic fish game, URWPGSim2D is the assigned platform for Chinese underwater robot contest and Robot cup underwater program. By now on URWPGSim2D, there is only static obstacles, thus short of changeableness. In order to improve the changeableness and innova...

The key element of models of contest is the Contest Success Function (CSF) which specifies the winning probabilities of agents. The existing axiomatizations of CSFs assume that contestants can make only one type of investment. This paper generalizes these axiomatizations to the case where each agent can have multiple types of investments. This allows us to provide a unified framework to extend ...

Crowdsourcing offers unprecedented potential for solving tasks efficiently by tapping into the skills of large groups of people. A salient feature of crowdsourcing--its openness of entry--makes it vulnerable to malicious behaviour. Such behaviour took place in a number of recent popular crowdsourcing competitions. We provide game-theoretic analysis of a fundamental trade-off between the potenti...

This contest involved the running and evaluation of computer vision and pattern recognition techniques on different data sets with known groundtruth. The contest included three areas; binary shape recognition, symbol recognition and image flow estimation. A package was made available for each area. Each package contained either real images with manual groundtruth or programs to generate data se...

The means of contest design may include differential taxation of the prize. This paper considers all-pay auctions under complete information and establishes that, given a revenue-maximizing contest designer who faces a balanced-budget constraint, the optimal taxation scheme corresponding to an all-pay auction is appealing in two senses. First, it ensures extreme equitable final prize valuations...

In this work, we describe a conditional random fields (CRF) based system for Part-OfSpeech (POS) tagging of code-mixed Indian social media text as part of our participation in the tool contest on POS tagging for codemixed Indian social media text, held in conjunction with the 2016 International Conference on Natural Language Processing, IIT(BHU), India. We participated only in constrained mode ...

Following the experience of the rst edition of the international symbol recognition contest held during GREC'03 in Barcelona, a second edition has been organized during GREC'05. In this paper, rst, we bring to mind the general principles of both contests before presenting more speci cally the details of this last edition. In particular, we describe the dataset used in the contest, the methods t...
