WebFeb 22, 2024 · This chapter provides an overview of different types of dataset characteristics, which are sometimes also referred to as metafeatures. These are of different types, and include so-called simple, statistical, information-theoretic, model-based, complexitybased, and performance-based metafeatures. Test datasets must be representative of the entire target population of images, i.e., sufficiently diverse and unbiased. To minimize spurious correlations between confounding variables and the target variable and to uncover shortcut learning in AI methods, all dimensions of biological and technical variability … See more Compiling a test dataset requires a detailed description of the intended use of the AI solution to be tested. The intended use must clearly … See more AI solutions that are very accurate on average often perform much worse on certain subsets of their target population of images94, a … See more Any test dataset is a sample from the target population of images, thus any performance metric computed on a test dataset is subject to sampling error. In order to draw reliable … See more Biases can make test datasets unsuitable for evaluating the performance of AI algorithms.
