The type "bool" is a fundamental C++ type that can take on the values "true" and "false". When a non-bool x is converted to a bool, non-zero becomes true and zero becomes false, as if you had written x != 0. When bool is converted to non-bool, true becomes 1 and false ...
The output of the Pointer Network is a distribution over positions in the input sequence, while S2V-DQN outputs Q-values for each action in a given state. In summary, the main difference between Pointer Network and S2V-DQN lies in the problems they are designed to solve and the underlying ...
There's often confusion about the difference between the following three declarations in Objective-C: id foo1; NSObject *foo2; id<NSObject> foo3; The first one is the most common. It simply declares a pointer to some Objective-C object (see/usr/include/objc/objc.h).idgives the compil...
