Ground Truth
The concept of ground truth is a well-established principle in cartography, where data collected at a distance are confirmed by measurements made on location. Those local measurements are used to calibrate remote sensing devices, verify or correct experimental inferences, and update geographic databases. Ground truth observations also provide a means of training and supervising image classifica...
متن کاملThe Temperament Police: The Truth, the Ground Truth, and Nothing but the Truth
The tuning system of a keyboard instrument is chosen so that frequently used musical intervals sound as consonant as possible. Temperament refers to the compromise arising from the fact that not all intervals can be maximally consonant simultaneously. Recent work showed that it is possible to estimate temperament from audio recordings with no prior knowledge of the musical score, using a conser...
متن کاملImage Clustering without Ground Truth
Cluster analysis has become one of the most exercised research areas over the past few decades in computer science. As a consequence, numerous clustering algorithms have already been developed to find appropriate partitions of a set of objects. Given multiple such clustering solutions, it is a challenging task to obtain an ensemble of these solutions. This becomes more challenging when the grou...
متن کاملOn Reliable Crowdsourcing and the Use of Ground Truth Information
Using some expert labels or control questions with known answers may significantly improve the reliabilities of crowdsourcing systems, but with high cost that may not be feasible at large scale. This raises important problems on how to optimally integrate such additional, expensive but accurate information with the cheap but unreliable crowd labels, addressing which is critical to build more re...
متن کاملCrowdsourcing Ambiguity-Aware Ground Truth
The process of gathering ground truth data through human annotation is a major bottleneck in the use of information extraction methods. Crowdsourcing-based approaches are gaining popularity in the attempt to solve the issues related to volume of data and lack of annotators. Typically these practices use inter-annotator agreement as a measure of quality. However, this assumption often creates is...
