Companies are looking to develop a variety of tools to protect their creations, says Mikel Rodriguez, director of the Artificial Intelligence and Autonomy Innovation Center at MITRE.
"There is tremendous value locked into today's machine-learning models, and as companies expose ML models via APIs, these threats are not hypothetical," he says. "Not only do you have to consider the intellectual property of the models and the cost to label millions of training samples, but also the raw computing power represents a significant investment."
