 Each operation invocation conceptually returns a distinct new value, without
 changing the value of any other {{MLOperand}}. 
 
-Internally, the {{MLGraphBuilder}} methods such as {{MLGraphBuilder/gemm()}} create an [=implementation-defined=] <dfn>platform operator</dfn> which is held by the {{MLOperand}} or {{MLActivation}}, which perform the actual operation on the input data when the computation is run. An {{MLOperand}} also holds an [=implementation-defined=] <dfn>platform operand</dfn>, which references the operand in the underlying computational graph, and is connected to [=platform operators=] as input and/or output.

 The runtime values (of {{MLOperand}}s) are tensors, which are essentially multidimensional
 arrays. The representation of the tensors is implementation dependent, but it typically
