appropriate words, I believe the effect will be very good. If you can't use it after you've modified it, you can overwrite the backup back. Here are some of the shortcut keys that are commonly used in MyEclipse:1, toggle edit point ALT + 2. View open file Ctr + E.3, make full use of the template is the main definition of their own.4, custom shortcut key generation getter and setter.5, delete when try not to backspace or delete key, row level

mathematical expressions are: Among them, Yi refers to the real class I samples belong to 0 or 1,PI indicates that the first sample belongs to the probability of category 1, so that the two parts of the formula will only choose one for each sample, because there is a certain 0, when the prediction and the actual category exactly match, then two parts are 0, which assumes 0log0=0.AUC (area under Curve)ClickThrough Rate for CTR (click through rate) onl
