From: Vanessa Didelez Sent: August 26, 2020 1:26 PM To: M. Abrahamowicz, Dr. Subject: neural nets longitudinal data Dear Michal, thank you so much for organizing this great conference and the last session in particular - after 19:10 we were not able to submit questions or comments anymore... there was a question about neural nets for longituidnal data and both speakers did not seem to know: the AI community uses something called recurrent neural nets (RNN) for that; also see Ngufor, C., H. Van Houten, B. S. Caffo, N. D. Shah, et al. (2019). Mixed effect machine learning: A framework for predicting longitudinal change in hemoglobin A1c. J Biomed Inform 89: 56-67. Xiong, Y., H. J.
