In the python API 'def Sequential' (location: bindings/python/cntk/layers/higher_order_layers.py), there is a line as follows: \r\ncomposed_function = reduce(lambda f, g: f >> g, layers, identity)\r\nWhat does '>>' mean in CNTK?Is it a overload operation in CNTK?I know 'Sequential' is a function that accepts one argument and applies the given `functions` one after another,but how does it work?\r\nI am not sure whether I explain it clearly,any help would be appreciated."}}
