images so on the Left we see a bunch of real-world images of flowers in this case on the right we see random data the data on the left if your dataset looks like that it's very compressible because there are a lot of regularities at an intuitive level example often maybe pixels have roughly the same value whereas images on the right which are completely random there is no correlation between neighboring pixels that you can exploit to maybe compress how to represent the data on the right so two very different
