Problems solved by technology

[0003] However, the interaction event involves both parties, and the state of each participant can change dynamically. Therefore, it is very difficult to accurately express the characteristics of the interaction participants by comprehensively considering the various characteristics of the interaction participants.

Embodiment approach

[0148] According to an implementation manner, the aforementioned current node is a node: in the dynamic interaction graph, there is no connection edge pointing to this node.

[0149] In one embodiment, the first target node is a node to which no connecting edge exists in said dynamic interaction graph.

[0150] According to an implementation manner, the nodes within the predetermined range include: nodes within a preset number K of connection edges; and / or nodes whose interaction time is within a preset time range.

[0151] In one embodiment, each interaction event further includes the event characteristics of the interaction event; in this case, the node characteristics of each node include the attribute characteristics of the object corresponding to each node, and the interaction The event characteristic of the event.

[0152] In one embodiment, the apparatus 800 further includes a first prediction unit (not shown), configured to predict the classification category of the o...

Abstract

The embodiments of this specification provide a method and device for processing interaction sequence data. In this method, the dynamic interaction graph constructed according to the dynamic interaction sequence is first obtained, wherein the dynamic interaction sequence includes multiple interaction events arranged in chronological order, the dynamic interaction graph includes nodes representing each interaction object in each interaction event, and any node i The connection edge points to the two nodes corresponding to the previous interaction event that the object represented by the node i participated in. Then, in the dynamic interaction graph, the target subgraph corresponding to the target node is determined, and the target subgraph includes nodes within a predetermined range that start from the target node and reach via connecting edges; then, based on each The node features of the nodes and the pointing relationship of the connection edges between the nodes can determine the feature vector corresponding to the target node.

Description

technical field [0001] One or more embodiments of this specification relate to the field of machine learning, and in particular to a method and device for processing interaction sequence data using machine learning. Background technique [0002] In many scenarios, user interaction events need to be analyzed and processed. Interaction events are one of the basic elements of Internet events. For example, the click behavior when a user browses a page can be regarded as an interaction event between the user and the content block of the page, and the purchase behavior in e-commerce can be regarded as the interaction event between the user and the product. The interaction event between accounts, and the transfer behavior between accounts is the interaction event between users. A series of user interaction events contains the characteristics of the user's fine-grained habits and preferences, as well as the characteristics of the interactive objects, which are important feature sou...
