Learning Stochastic Behaviour from Aggregate Data

no code implementations10 Feb 2020 Shaojun Ma, Shu Liu, Hongyuan Zha, Haomin Zhou

Learning nonlinear dynamics from aggregate data is a challenging problem because the full trajectory of each individual is not available, namely, the individual observed at one time may not be observed at the next time point, or the identity of individual is unavailable.
