A journey to the heart of the society [From the Editor]
Serving as the editor-in-chief of IEEE Signal Processing Magazine (SPM) is a privilege and a blessing. Three years ago, when I first assumed the responsibility, I expected a journey similar to prior ones with other publications. Now at the end of this one, I am immensely gratified by what we, the editorial team, have accomplished and what I, together with authors, readers, guest editors, and the entire editorial team, have learned.
