CPU algorithm trains deep neural nets up to 15 times faster than top GPU trainers (2 minute read)

Computer scientists from Rice University have created an artificial intelligence software that can train deep neural networks 15 times faster on commodity processors than software that relies on graphic processors. The team built its system by recasting deep neural network training as a search problem that could be solved with hash tables. Companies can spend millions of dollars a week just to train and fine-tune their AI workloads, so the benefits of making commodity CPUs more efficient than specialized hardware cannot be understated.
