Artificial Datasets
Arcade Universe – An artificial dataset generator with images containing arcade games sprites such as tetris pentomino/tetromino objects. This generator is based on the O. Breleux’s bugland dataset generator.
A collection of datasets inspired by the ideas from BabyAISchool:
BabyAIShapesDatasets : distinguishing between 3 simple shapes
BabyAIImageAndQuestionDatasets : a question-image-answer dataset
Datasets generated for the purpose of an empirical evaluation of deep architectures (DeepVsShallowComparisonICML2007):
MnistVariations : introducing controlled variations in MNIST
RectanglesData : discriminating between wide and tall rectangles
ConvexNonConvex : discriminating between convex and nonconvex shapes
BackgroundCorrelation : controlling the degree of correlation in noisy MNIST backgrounds
