I'm not familiar with LQRs. Versus HMMs and linear autoregressive models, I think avoiding the need to predefine the form of the autoregression is a bigger leap than it might appear right now. I'd always been a neural network skeptic, thinking they're excessively complex for no benefit. It seems to me that's no longer true. I'm not certain that'll hold, but it's exciting.
