error view one is looking for and then given a test example give it a test image X right what what what they will do is it will select out let's say three out of my 64 basis functions here and it will take that test example and explain it or decompose it into a linear combination of in this case just three out of 64 of my basis functions okay so speaking loosely this algorithm has to quote invented edge detection right the algorithm is free to choose absolutely any basis functions at once but it shows but you know if you run it
