I’m going to guess that they meant Directed Acyclic Graphs or DAGs, which is a useful way to represent data dependencies and transformations, allowing formulation for GPU, CPU, NNA, DSP, FPGA, etc. If the macrostructure of the operations can be represented appropriately, automatic platform-specific optimization is more approachable.
