Fixing Security Vulnerabilities with AI in OSS-Fuzz
Yuntong Zhang, Jiawei Wang, Dominic Berzin +5
Critical open source software systems undergo significant validation in the form of lengthy fuzz campaigns. The fuzz campaigns typically conduct a biased random search over the dom…
Program Repair by Fuzzing over Patch and Input Space
Yuntong Zhang, Ridwan Shariffdeen, Gregory J. Duck +2
Fuzz testing (fuzzing) is a well-known method for exposing bugs/vulnerabilities in software systems. Popular fuzzers, such as AFL, use a biased random search over the domain of pro…
Patch Space Exploration using Static Analysis Feedback
Yuntong Zhang, Andreea Costea, Ridwan Shariffdeen +2
Automated Program Repair (APR) techniques typically rely on a given test-suite to guide the repair process. Apart from the need to provide test oracles, this makes the produced pat…
Efficient and Direct Inference of Heart Rate Variability using Both Signal Processing and Machine Learning
Yuntong Zhang, Jingye Xu, Mimi Xie +3
Heart Rate Variability (HRV) measures the variation of the time between consecutive heartbeats and is a major indicator of physical and mental health. Recent research has demonstra…
PPG-based Heart Rate Estimation with Efficient Sensor Sampling and Learning Models
Yuntong Zhang, Jingye Xu, Mimi Xie +4
Recent studies showed that Photoplethysmography (PPG) sensors embedded in wearable devices can estimate heart rate (HR) with high accuracy. However, despite of prior research effor…
