Automatic preprocessing of image data using UMAP in DimensionReduce

Posted 3 years ago

Hi Michael, you can explore the internals of the DimensionReducerFunction to check the preprocessor—ideally you should be able to do

Information[_DimensionReducerFunction, "FeatureExtractor"]

but we have not hook it up there yet. In the meantime you can check what the internal processor is doing (hover over each processor to see more info)

reducer[[1, "Processor"]]

reducer_processor

and apply it to an image

reducer[[1, "Processor"]] @* reducer[[1, "Preprocessor"]] @ RandomImage[]

reduced_dataset

Remember to use DimensionReduction instead of DimensionReduce in order to get the function and not the reduced data directly.

Thank you, that's helpful!
