Fooling NLP Systems Through Word Swapping
MIT researchers have built a system that fools natural-language processing systems by swapping words with synonyms: The software, developed by a team at MIT, looks for the words in a sentence that are most important to an NLP classifier and replaces them with a synonym that a human would find natural. For example, changing the sentence "The characters, cast in… Continue reading Fooling NLP Systems Through Word Swapping
Vulnerability Finding Using Machine Learning
Microsoft is training a machine-learning system to find software bugs: At Microsoft, 47,000 developers generate nearly 30 thousand bugs a month. These items get stored across over 100 AzureDevOps and GitHub repositories. To better label and prioritize … Continue reading Vulnerability Finding Using Machine Learning
Vulnerability Finding Using Machine Learning
Microsoft is training a machine-learning system to find software bugs: At Microsoft, 47,000 developers generate nearly 30 thousand bugs a month. These items get stored across over 100 AzureDevOps and GitHub repositories. To better label and prioritize bugs at that scale, we couldn’t just apply more people to the problem. However, large volumes of semi-curated data are perfect for machine… Continue reading Vulnerability Finding Using Machine Learning
Clearview AI and Facial Recognition
The New York Times has a long story about Clearview AI, a small company that scrapes identified photos of people from pretty much everywhere, and then uses unstated magical AI technology to identify people in other photos. His tiny company, Clearview AI, devised a groundbreaking facial recognition app. You take a picture of a person, upload it and get to… Continue reading Clearview AI and Facial Recognition
Artificial Personas and Public Discourse
Presidential campaign season is officially, officially, upon us now, which means it’s time to confront the weird and insidious ways in which technology is warping politics. One of the biggest threats on the horizon: artificial personas are coming, and they’re poised to take over political debate. The risk arises from two separate threads coming together: artificial intelligence-driven text generation and… Continue reading Artificial Personas and Public Discourse

Fabricated Voice Used in Financial Fraud
This seems to be an identity theft first: Criminals used artificial intelligence-based software to impersonate a chief executive’s voice and demand a fraudulent transfer of €220,000 ($243,000) in March in what cybercrime experts described as an unusual case of artificial intelligence being used in hacking. Another news article…. Continue reading Fabricated Voice Used in Financial Fraud
AI Emotion-Detection Arms Race
Voice systems are increasingly using AI techniques to determine emotion. A new paper describes an AI-based countermeasure to mask emotion in spoken words. Their method for masking emotion involves collecting speech, analyzing it, and extracting emotional features from the raw signal. Next, an AI program trains on this signal and replaces the emotional indicators in speech, flattening them. Finally, a… Continue reading AI Emotion-Detection Arms Race
