Quality matters, especially in sharing knowledge [From the Editor]
These days, all it takes is a few clicks of the mouse for a person to access massive amounts of information and data through Web pages, blogs, or social-centric Web sites. This easy-to-access and fast-to-find information is what makes the era we live in a special one. But with all this advancements comes the question of quality . Does the shared knowledge have high quality? What sources can one rely on to access quality knowledge? This is where publications such as IEEE Signal Processing Magazine (SPM) play an important role. Signal processing as indicated by our new editor-in-chief, Dr. Li Deng, is going through a transformation from focusing on low-level signals such as waveforms to dealing with semantic and human-centric signals. This signal processing transformation has to be accompanied by a metamorphosis in how the community exchanges high-quality knowledge and how the community members learn from each other.
