Technology: Frequently Asked QuestionsSo is this analog, or digital? This is not traditional analog. It is not traditional digital. It is a fundamentally new way of processing. For probability processing, we've adopted some of the best ideas from both analog and digital. We run on a clock like a digital circuit. Our circuits are modular and scalable. Our designs are made up of many instances of a small family of standard cells. However, we don't force our variables to be just 0s and 1s. Our variables take on any possible probability value: any analog value between 0 and 1. So is it fuzzy logic? Probability processing is Bayesian. The probabilities of different outcomes must add up to one. In fuzzy logic, you are allowed to be 60% sure that a coin is heads, and 60% sure that it is tails, both at the same time. That is not allowed in Lyric's probability processing technology. If we are 60% certain that a coin is heads, the probability that it is tails must be 40% -- no other value is consistent. So is this like a neural net? Although Lyric's technology can be adaptive and can implement learning algorithms, it is fundamentally different from neural nets. Neural nets must be trained to exhibit desired behaviors. Once they're trained, neural nets can be very hard to understand and nearly impossible to debug. Lyric's technology can be programmed using PSBL to implement predictable, understandable, deterministic behaviors. |
