The electronics industry over the past several years has made tremendous strides in creating artificial intelligence in a manner imagined by Allen Turing in the 1940s. The convergence of algorithmic advances in multilayer neural networks, the evolution of PC GPUs as massively parallel processing accelerators, and the availability of massive data sets fueled by the Internet and widely deployed sensors — big data — has enabled a renaissance in software neural network modeling techniques commonly referred to as “deep learning,” or “DL.”
