Deep learning training is the process whereby a deep neural network is taught using a set of data such that it can make predictions for a modeled event. It can involve trial and error, and it can take many tries until the network is able to accurately draw conclusions based on the training data. Constructing training data sets for deep learning models involves billions of data samples, curated by crawling the Internet. Trust is an implicit part of the arrangement: genuine data samples are required to model real events. This important information came to us from IEEE Spectrum in their article, “Protecting AI Models from “Data Poisoning”.
Trust is under threat by a new kind of cyberattack called data poisoning – when trawled data assembled for deep-learning training has been intentionally compromised with false patterns. A team of computer scientists have demonstrated two model data poisoning attacks. Thus far, there is no evidence of these attacks having yet been carried out. The attacks are expected to happen in text-based machine-learning models trained by the Internet.
Data poisoning can render machine learning models inaccurate, possibly resulting in faulty bases and bad decision-making. With no easy fixes available, security pros must focus on prevention and detection.
