GAUSSIAN RANDOM VECTORS AND PROCESSES
A random variable U with this density, for arbitraryµ and 0, is defined to be a Gaussian random variable and is denoted U ⇠ N(µ,2). The added generality of a mean often obscures formulas; we usually assume zero-mean rv’s and random vectors (rv’s) and add means later if necessary. Recall that any rv U with a

www.rle.mit.edumachine learning; spatial architectures; VLSI I. INTRODUCTION Deep neural networks (DNNs) are currently the founda-tion for many modern artificial intelligence (AI) applica-tions [1]. Since the breakthrough application of DNNs to speech recognition [2] and image recognition [3], the number of applications that use DNNs has exploded. These
