My idea was to explode ingredients and create a kind of one-hot vector and employ kmodes to look at how the different recipes cluster together. 1. If we're feeling ambitious, we might toss in animation for a temporal dimension (the prime example is Hans Rosling showing 5 variables at once in the Gapminder Talk. Many biomineralized tissues (such as teeth and bone) are hybrid inorganic-organic materials whose properties are determined by their convoluted internal structures. When it comes to clustering, work with a sample. how to visualize high dimensional data clustering; how to visualize high dimensional data clustering.
