Ah, I get the question now. If I understand correctly CSR, it stores indexes and values as a list. I store them also as a list - that's why the comparison is there. The difference is that with CSR you store say 15% of the values from a given row. I store all of them, but use only the first X% of them. The X% varies and depends on the input vector. They are stored sorted, from the one of a highest absolute value to the lowest absolute value. It's after midnight so my explanations may not be too good now, but I hope the pseudocode on the page and the examples explain it slightly better. I'll be fixing grammar / typos, and asking ChatGPT to rewrite the page text for me tomorrow to make it more readable :)
