More on "Long Short Term Memory"

Following up on a recent blog of mine, Marcelo Medeiros kindly alerted me to this very nice paper by Livia Paranhos, "Predicting Inflation with Neural Networks".  She is a Ph.D. candidate in Economics at Warwick, working with NNs in macro forecasting.  I'm still wondering whether/how "Long Short Term Memory" is related to conventional statistical long memory in the sense of fractional integration.
