Effect of Errors in Ground Truth on Classification Accuracy

The effect of errors in ground truth on the estimated thematic accuracy of a classifier is considered. A relationship is derived between the true accuracy of a classifier relative to ground truth without errors, the actual accuracy of the ground truth used, and the measured accuracy of the classifier as a function of the number of classes. We show that if the accuracy of the ground truth is kno...

Training Deep Learning based Denoisers without Ground Truth Data

Recent deep learning based denoisers are trained to minimize the mean squared error (MSE) between the output of a network and the ground truth noiseless image in the training data. Thus, it is crucial to have high quality noiseless training data for high performance denoisers. Unfortunately, in some application areas such as medical imaging, it is expensive or even infeasible to acquire such a ...

Ground truth for automatic music mood classification

Automatic music classification based on audio signals provides a core technology for tools that help users to manage and browse their music collections. Since “mood” is also used as a browsing criterium, automatic mood classification could support the creation of the necessary metadata. We have developed a method to obtain a reliable “ground truth” database for automatic music mood classificati...

What is gold standard and what is ground truth?

Clinical decision-making is complex and based upon accurate evaluation of clinical findings using diagnostic tests and reference standard data. Given that many aspects of dental examination are not direct measures, but rely on indirect measures, it is important for clinicians to understand the basic principles and terms used to assess the accuracy of diagnostic tests and to appropriately evalua...

On Refining Twitter Lists as Ground Truth Data for Multi-community User Classification

To help scholars and businesses understand and analyse Twitter users, it is useful to have classifiers that can identify the communities that a given user belongs to, e.g. business or politics. Obtaining high quality training data is an important step towards producing an effective multi-community classifier. An efficient approach for creating such ground truth data is to extract users from exi...
