Abstract

The invention provides a time sequence processing method and device based on a computational flow graph and a storage medium. The method comprises the following steps: carrying out sub-graph search based on a given end point node of a calculation flow graph to obtain a sub-graph required for calculating the end point node; Recording the degree of each node in the sub-graph, wherein the degree comprises an input degree; Traversing the subgraphs according to the recorded in-degree of the nodes, and determining a calculation execution sequence of the nodes; and performing calculation operation between the nodes based on the determined calculation execution sequence, and storing a calculation result. According to the embodiment of the invention, the execution efficiency of time sequence processing can be optimized.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a time series processing method, device and computer storage medium based on computational flow graphs. Background technique [0002] A time series is a series of values ​​obtained by observing a certain physical quantity at equal intervals. Time series exist widely in real life, covering financial, medical, biological and chemical fields. Time series often involve cumbersome and complex calculation processes, and there are often data dependencies between these calculation processes. [0003] Computational flow graphs clearly express this data dependency. Each process of time series processing represents an operation, nodes represent data, edges between nodes describe an operation, operations are described by one or more edges, and the direction of the edges represents the direction of data flow, so as to build a directional but A graph without loop closures is a com...
