The invention provides a mass image classification method based on distributed K-means, and belongs to the technical field of machine learning and image processing. The mass image classification method based on distributed K-means can be applied to large-scale image classification, adopts the distributed K-means algorithm to extract image characteristics on a big data processing platform Hadoop, and finally achieves the purpose of classifying large-scale images. According to the invention, through the design of performing dictionary learning on large-scale image data, and constructing a characteristic mapping function and a classification algorithm, a characteristic extracting algorithm based on the distributed K-means is provided on the basis of the big data processing platform Hadoop. The method avoids the tedious work of manually designing large-scale image characteristics, and reduces training time under the premise of ensuring classification accuracy; and the achievement of the invention has significant meanings in aspects of large-scale database management, military and medical treatment.

The present invention provides a method and an apparatus for adapting a communications network of a plurality of wireless access nodes, such as base stations to a changing environment. The method comprises determining a current location of at least a first user in the communications network, identifying a need for change in at least one parameter associated with a position of a first base station of the plurality of base stations based on the current location of the first user, and implementing a first response in the communications network in response to the need for change for the first base station. In this way, a self-deploying wireless access network may autonomously reposition base stations in a changing environment of user distributions across a coverage area and / or user demand by users of wireless communication devices, such as mobile units. Using indirect communication between the base stations capable of operating with different standards or protocols, a distributed algorithm may adapt the network to the changing environment. Such adaptation of the network in a distributed manner may control overall network costs of providing wireless services to mobile users.
