every time it chooses to learn basis functions that look like these edges and what this decomposition says is that this image X is 0.8 times H number 36 plus 0.3 times H number 42 plus 0.5 times H number 63 okay so if you will this is saying this is now decompose the image in terms of what edges appear in this image and this gives a high-level more succinct more compact representation of the image and also probably a more useful one right because it's more useful to know where the edges are in the image that you know where the
