presumably the more codes there are in your code book the more tiles there are the more complicated the function that you're trying to approximate so these are two approaches well I'm going to get one that really expands upon these two and it it is leveraging the fact that we can was leveraging really the the fact that lots of data sets of particular image type data sets we have a reasonable reasonably true property that the the the training data live on low lowered that doesn't that be low dimensional but lower dimensional
