Abstract:
A trajectory data query method includes establishing a spatial-temporal index and an inverted index for trajectory data in a spatial-temporal database, where the inverted index is used to form a first relationship correspondence table that includes a correspondence between each trajectory and its associated index leaf node; performing sampling for an index leaf node included in a space area specified by a user, where a quantity of index leaf nodes in the space area and a quantity of index leaf nodes obtained by sampling are determined; determining, according to the index leaf nodes obtained by sampling and the first relationship correspondence table, a correspondence between each trajectory included in the index leaf nodes obtained by sampling and an index leaf node associated with the trajectory, to form a second relationship correspondence table; and determining an unbiased estimation operator according to the quantity of index leaf nodes in the space area.
Abstract:
A method for processing information by an intelligent agent and the intelligent agent, where the method comprises: a first intelligent agent sends a request message to a second intelligent agent, where the request message includes an invitation message or a recommendation message; the first intelligent agent receives a decision message fed back by the second intelligent agent, where the decision message is determined according to the invitation message or the recommendation message and a knowledge model of the second intelligent agent; and the first intelligent agent updates, according to the decision message, a knowledge model of the first intelligent agent or sends a notification message to a first user account corresponding to the first intelligent agent. By using these technical solutions, information on a social network may be learned and processed by means of interaction with another intelligent agent, thereby implementing mining of data on the social network.
Abstract:
A picture ranking method and a terminal comprises acquiring pictures stored in a terminal, detecting whether the pictures are first-type pictures, where a first-type picture refers to a picture including a human face, and when the pictures are first-type pictures, ranking the pictures according to a social relation model, or when the pictures are not first-type pictures, ranking the pictures according to a preset rule.
Abstract:
The present application provides a path planning method and a controller. The method includes: acquiring data flow information of a to-be-transmitted job in a software-defined network, where the job includes at least one target data flow, and the data flow information of the job includes: a source address, a destination address, and a volume of each target data flow; and performing path planning according to the data flow information, and obtaining a job transmission path used to ensure that the job is transmitted in the software-defined network in a shortest job transmission time, where the job transmission path includes a transmission path corresponding to each target data flow in the job. The present application improves a data transmission speed of a job in an SDN network.
Abstract:
A method for recognizing a target object in an image, and an apparatus, where the method includes extracting feature data from an image, and transforming the extracted feature data into a uniform expression, performing automatic clustering for features in the image according to the feature data in the uniform expression and a historical clustering result, grouping a target object of a known class included in an automatic clustering result into the corresponding known class, in order to recognize a target object of the known class in the image, and training a classifier in a machine learning manner, for a target object of an unknown class included in the automatic clustering result, in order to recognize a target object of an unknown class in the image. In the embodiments of the present invention, recognizing a target object of an unknown class can be implemented.
Abstract:
A method for determining virtual machine migration relates to the field of communications and can reduce a deployment cost. The method includes a client in a host machine obtains a unique identifier of a virtual machine on the host machine and an address of the host machine; and if the unique identifier of the virtual machine does not exist in a local record of the client, the client sends a packet to a server in a network in which the host machine is located, where the packet carries the unique identifier of the virtual machine and the address of the host machine, so that the server determines, according to the unique identifier of the virtual machine and the address of the host machine, whether the virtual machine is migrated; and the client adds the unique identifier of the virtual machine to the local record to update the local record.

Abstract:
A method and a system for processing lifelong learning of a terminal, and an apparatus is presented. The method for processing lifelong learning of a terminal according to the present disclosure includes sending, to a server, a request for downloading a function module, where the download request includes description information of the function module; receiving the function module that is sent by the server and is corresponding to the description information; and using the function module to expand and/or update a local function. According to the embodiments of the present disclosure, the lifelong learning of the terminal is implemented, and a problem in the prior art that the terminal cannot perform function expansion and updating is resolved.
