Finding Signals in the Noise From hidden patterns to usable systems Sunil Kumar Kopparapu Much of science is the art of finding signal in noise. Looking back, that idea connects every stage of this journey, from algebra and signal processing to neural networks , computer vision, and speech technologies. Looking back, the journey was never driven by a grand plan. Rather, it unfolded through a series of small discoveries, each opening a door to a larger world. One of the earliest lessons was that aptitude is often acquired rather than inherited. As a schoolboy, mathematics did not come naturally. It was only around Class V or VI that algebra began to make sense, thanks to my father. What had first appeared to be a collection of mysterious symbols revealed, in less than fifteen minutes, an underlying logic. There was a quiet satisfaction in realizing that abstract notation could describe concrete relationships. In retrospect, this may have been the first encount...
