Machine learning has an alarming threat: undetectable backdoors

This article is part of our coverage of the latest in AI research. If an adversary gives you a machine learning model and secretly plants a malicious backdoor in it, what are the chances that you can discover it? The security of machine learning is becoming increasingly critical as ML models find their way into a growing number of applications. The new study focuses on the security threats of delegating the training and development of machine learning models to third parties and service providers. With the shortage of AI talent and resources, many organizations are outsourcing their machine learning work, using pre-trained models or online ML services.
