Threshold dynamics of a delayed predator–prey model with impulse via the basic reproduction number

Xiangsen Liu, Binxiang Dai • Advances in Difference Equations (2018)

Abstract In this paper, we study a delayed predator–prey model with impulse and, in particular, the existence of the predator-free periodic solution. We employ the approach and techniques coming from epidemiology and calculate the basic rep...

Multi-step prediction in linearized latent state spaces for representation learning

Andrii Tytarenko • Sistemnì Doslìdženâ ta Informacìjnì Tehnologìï (2022)

In this paper, we derive a novel method as a generalization over LCEs such as E2C. The method develops the idea of learning a locally linear state space by adding a multi-step prediction, thus allowing for more explicit control over the cur...
