Artificial Neural Networks adoption of the Deep Learning algorithm (DL) has limited the development of algorithms that can deal with generality and the mapping of associations DL designs rapidly adopted Parallel Arrays of Multiply-Accumulate (MAC) solutions using High Bandwidth Memory (HBM)Memory is internal to the algorithm used and has no external object “association” tetherDependence on a purely statistical algorithm with little reference to a memory framework is DLs weakest link
