By leveraging big data and deep learning, in recent years, AI technologies have made significant progress. They have been adopted in many applications, including malware detection, image classification, and stock market prediction. As our society becomes more automated, more and more systems will rely on AI techniques. And instead of augmenting human decisions, some AI systems will make their own decisions and execute autonomously. This is extremely risky especially for mission-critical fields (like homeland security, medical diagnosis, and self-driving vehicles). In fact, the advances in AI outpace efforts to curb its potential hazards, because AI systems are vulnerable due to various attacks and biases.
This project aims to develop innovative system testing and data governance engines to identify AI system vulnerabilities, defend against advanced attacks, improve technical robustness, and mitigate technical unfairness/biases. Our engines leverage fine-grained reliability assessment, generalized robustness enhancement, and hardware-based privacy protection techniques to secure both AI model and data throughout the system development life cycle.
Since AI is being applied to more domains for mission-critical tasks, our engines can offer “AI System Testing and Data Governance” as a service to make businesses in these domains more reliable, trustworthy, transparent, and secure. We are developing new solutions to support a variety of AI systems with different types of data, thus can be applied to an enormous variety of businesses, including autonomous driving, biometric authentication, finance, healthcare, IoT devices, smart factories, and more.

Chris White discusses the evolution of scientific disciplines, which often begin with exploration driven by curiosity and experimentation. As fields grow in complexity and cost, they shift to theoretical frameworks that optimize research. This transition is crucial for sustainable progress. Currently,
The development of next-generation sequencing (NGS) has enabled the discovery of cancer-specific driver gene alternations, making precision medicine possible. However, accurategenetic testing requires a sufficient amount of tumor cells in the specimen. The evaluation of tumor content ratio (TCR) from
NEC Laboratories Europe and NEC Laboratories America have developed MateriAI, an AI-based, material design platform that accelerates the development of new, environmentally friendly materials. The prototype platform was initially designed to overcome major hurdles in the creation of new synthetic, organic
Data crowdsourcing is an increasingly pervasive and lifestyle-changing technology due to the flywheel effect that results from the interaction between the Internet of Things and Cloud Computing. This paper presents the Citizen Science for the Sea with Information Technologies (C4Sea-IT) framework. It

The age of computer vision is upon us, and it’s transforming the way we live, work and interact with the world. Nearly every industry has found a use case to grow revenue, reduce cost, or create exceptional experiences using computer vision. From self-driving cars to retail automation, surgeons to
We are helping to safely bring the first woman astronaut to the moon as part of NASA – National Aeronautics and Space Administration’s Artemis Project with our System Invariant Analysis Technology (SIAT). With Lockheed Martin Space’s T-Tauri AI platform, our SIAT analytics engine takes the data from
By 2024, the spacecraft “Orion” developed by Lockheed Martin will bring humans to the moon in NASA’s Artemis program. The system invariant analysis technology, one of NEC’s Artificial Intelligence technologies, will perform checks to ensure that the spacecraft is tested and operating properly during
By employing distributed fiber optic sensing (DFOS) technologies, field deployed fiber cables can be utilized as not only communication media for data transmissions but also sensing media for continuously monitoring of the physical phenomenon along the entire route. The fiber can be used to monitor ambient
Distributed fiber optic sensing systems (DFOS) allow deployed fiber cables to be sensing media, not only dedicated function of data transmission.
