can see if you do it with the true w you're really good at the beginning if you do it with a regress w we can see that before you can you so this is the small version of this plot right here this is like this uh section i think yeah you know you improve however we can also learn this pi function we can also learn the features where if we're not given the features maybe we can learn the features and they say well we can do this with but also by regression so here what we can do is we can find the function that minimizes the function
