The rules use compute node identifiers for LNCNs located at the particular datacenter and network addresses for LNCNs located at other datacenters as the local manager does not store data regarding compute nodes located at the other datacenters.

Dynamic growth model construction method and system for crop canopy structure, and storable medium

Through exploration of the characteristics of a crop canopy structure and the variation laws in the crop development processes, a three-dimensional crop canopy structure model and a dynamic maize growth simulation are established by fusing the three-dimensional crop canopy structure model. The model describes the crop growth and development stages by adopting growing degree-days, carries out dynamic simulation on a two-dimensional maize canopy structure by adopting a Logistic equation, and characterizes veins, leaf margin and the like by adopting a spatial topological structure. On this basis, a dynamic simulation method for a three-dimensional spatial crop canopy structure is finally established, the coupling simulation of multiple hydrothermal carbonization processes in a complex farmland ecosystem is realized, and thus the simulation capability and universality of the crop model are effectively improved.

Video recommendation generation using video content based on bi-directional prediction

In some embodiments, a method receives a history of videos that were viewed on a video delivery system as a first sentence in a sequential order and a target video as a second sentence as input to a prediction network. The prediction network analyzes representations for the history of videos and a representation of the target video. The prediction network generates a session representation based on bidirectionally analyzing a sequence of the first representations and the second representation. The method uses the session representation to determine whether to recommend the target video.
