Where can I see a full list of ExampleData?

Question

Using ExampleData, we can extract data for Machine Learning, Sound and others. From the reference of the Wolfram Language, I can see a full list of types of data, like machine learning, dataset, audio, etc. But where can I see what data can I extract for every type?

Answer 1

Get the categories of example data:

ExampleData[]
(* {"AerialImage", "Audio", "ColorTexture", "Dataset", \
"Geometry3D", "LinearProgramming", "MachineLearning", "Matrix", \
"NetworkGraph", "Sound", "Statistics", "TestAnimation", "TestImage", \
"TestImage3D", "TestImageSet", "Text", "Texture"} *)

Get the available data in one category:

ExampleData["MachineLearning"]
(* {{"MachineLearning", "BostonHomes"}, {"MachineLearning", 
  "FisherIris"}, {"MachineLearning", "MNIST"}, {"MachineLearning", 
  "MovieReview"}, {"MachineLearning", "Mushroom"}, {"MachineLearning",
   "Satellite"}, {"MachineLearning", "Titanic"}, {"MachineLearning", 
  "UCILetter"}, {"MachineLearning", "WineQuality"}} *)

Get available properties of one dataset:

ExampleData[{"MachineLearning", "BostonHomes"}, "Properties"]
(* {"Data", "Description", "Data", "Dimensions", \
"LearningTask", "LongDescription", "MissingData", "Name", "Source", \
"TestData", "TrainingData", "VariableDescriptions", "VariableTypes"} *)
