-oriented program is written like this:Bart = Student ('Bart Simpson',Student ('Lisa Simpson') ,Bart.print_score () Lisa.print_score ( )The idea of object-oriented design is from the nature, because in nature, the concept of classes (class) and instances (Instance) is very natural. Class is an abstract concept, such as our definition of class--student, which refers to the concept of a student, while an instance (Instance) is a specific Student, for ex

All models/algorithms published by the LISA Lab should has reference implementations in PYLEARN2. PYLEARN2 may wrap other libraries such as Scikits.learn if this is practical PYLEARN2 differs from Scikits.learn in, PYLEARN2 aims to provide great flexibility and make it possible for

Beautiful warm photos, fresh and moving pictures, in the enjoyment of them, add a beautiful border how about it? A piece of land plus? That's a lot of trouble! It is much more convenient to record a "border action" with the action panel of Photoshop. Just open the photo you want to add a border to, and then click the "Execute Action" button on the action panel, and the action will be done by the action (action can be interpreted as Photoshop's "macro", which can combine a series of commands into
