And that makes meanings matter even more.

A hybrid learning framework uses a collective anomaly to analyze patterns in denial-of-service attacks along with data clustering to distinguish an attack from normal network traffic. In two evaluation datasets, the framework achieved higher hit rates relative to existing anomaly-detection techniques.

Rather than continue the expensive and time-consuming quest for transistor replacement, the authors argue that 3D chips coupled with new computer architectures can keep Moore's law on its traditional scaling path.

To maintain Moore's law, the semiconductor industry decided a decade ago that a new transistor was imperative. That silver bullet has yet to materialize, but computer design innovations are now maintaining or even exceeding expected scaling progress. This theme issue gives a cross-sectional view of these new scaling drivers.

To enable autonomous driving, a computing stack must simultaneously ensure high performance, consume minimal power, and have low thermal dissipation--all at an acceptable cost. An architecture that matches workload to computing units and implements task time-sharing can meet these requirements.

Recent advances in deep learning for image recognition have spawned numerous challenge-based learning competitions in which participants can use a low-cost GPU graphics card to accomplish goals that required expensive resources in the recent past. Students are encouraged to explore this exciting new field of research by entering these competitions. Scooter Willis, "Stand on the Shoulders of Giants", Computer, vol.

The authors propose an agile, softwarized infrastructure for the flexible, cost-effective, secure, and privacy-preserving deployment of Internet of Things systems for smart healthcare applications and services.

WiSE-Mnet is a holistic simulator that abstracts the key functions of smart-camera networks and models the main operations to account for hardware capabilities, the complexities of visual data, and their associated high-data-rate communication.

An architecture firm used the hackathon model to design spaces that integrate lifelong learning with other aspects of our daily lives, such as working, playing, and socializing.

Penetration testing is a crucial defense against common web application security threats such as SQL injection and cross-site scripting attacks. A proposed web vulnerability scanner automatically generates test data with combinative evasion techniques, significantly expanding test coverage and revealing more vulnerabilities.
