"The cost of training is the actual bottleneck in AI," said Anshumali Shrivastava, an assistant professor of computer science at Rice's Brown School of Engineering. "Companies are spending millions of dollars a week just to train and fine-tune their AI workloads." Shrivastava and collaborators from Rice and Intel will present research that addresses that bottleneck April 8 at the machine learning systems conference MLSys.
