wangwei updated SINGA-60:
-------------------------
Description:
The learning rate of SGD typically changes through time.
There are many different ways to change the learning rate of SGD. SINGA has
implemented a couple of changing methods. But users may want to implement their
own changing method. To make this part modular, this ticket is going to create
a base learning rate generator, e.g. called LRGen, which is declared like,
{code}
class LRGenerator {
public:
virtual float Get (int step) = 0;
protected:
LRProto proto_;
};
{code}
Users can then inherit LRGenerator to implement the their own changing
algorithm in the `Get(int step)`.
Users can also add configurations for their generator by extending the base
LRProto.

a base learning rate generator called LRGen, which is declared like,

class LRGen {
public:
virtual float operator() (int step) = 0;
protected:
LRProto proto_;

Users can then inherit LRGen to implement the their own changing algorithm in
the `operator()(int step)`.
Users can also add configurations for their generator by extending the base
LRProto.
