News editors obtained the following quote from the background information suppli ed by the inventors:“There are two kinds of programming framework commonly used in machine learning (ML): a) old-schoolgraph-based frameworks like TensorFlow 1, and b) eager execution frameworks like PyTorch or TensorFlow2. Eager executi on steps through the source program sequentially and dispatches each operation f rom thesource program to be executed immediately, as-and-when they are encounte red. A graph-based approachon the other hand compiles the entire program in adv ance based on a graph representing relationshipsbetween the various variables a nd operations within the source program, and then only once compiledexecutes th e compiled program. Eager and graph-based programming frameworks can also be ext endedto other applications, not just machine learning.
