chainer.functions
Chainer provides basic ~chainer.FunctionNode implementations in the chainer.functions package. Most of them are wrapped by plain Python functions, which users should use.
Note
As of v1.5, the concept of parameterized functions are gone, and they are replaced by corresponding ~chainer.Link implementations. They are found in the ~chainer.links namespace.
