Hi Jake, the tutorial looks great! Unfortunately, I haven't got the time to go through all of it yet, however, I spotted something that confused me: in the last paragraph of Section 2.3.4 you state: "Of the points we label quasars, only 14% of them are correctly labeled." By "we labeled quasars" you mean those points who's true label is positive (=quasar) and not who's predicted label is positive? Because the latter would refer to precision rather than recall. Maybe you should change the wording to avoid confusion.
BTW: "we are correctly identifying 95% of all quasars." should actually be "among the points identified as quasars 95% are correct" because the former would be recall rather than precision. best, Peter 2012/2/27 Jacob VanderPlas <[email protected]>: > Thanks for all the feedback. > I pushed an update this morning which addressing some of the easy fixes > that were brought up, as well as adding the final two exercises.
