Abstract: This application discloses a polar code retransmission method and apparatus, to achieve an encoding gain. The method includes: when decoding of the first code word fails, performing polar code encoding on K first to-be-encoded bits and K? second to-be-encoded bits based on a second information bit position set to obtain a second code word, where elements in the second information bit position set are used to indicate positions of the to-be-encoded bits, and an element that is in the second information bit position set and that is used to indicate a position of a first to-be-encoded bit is a sum of N and an element that is in the first information bit position set and that is used to indicate the position of the first to-be-encoded bit; and sending a subcode in the second code word other than the first code word to the decoding device.

Abstract: An operation behavior monitoring method includes: obtaining target historical operation behavior data of a target user, and performing data statistics on the target historical operation behavior data according to different dimensions, to build a multi-dimensional coordinate system; when a target operation behavior is received, determining a target data item corresponding to the target operation behavior in each dimension, determining whether a labeling point corresponding to the target data item exists in the multi-dimensional coordinate system or not; if yes, increasing the density of the labeling points by one; if not, determining a labeling point corresponding to the target data item in the multi-dimensional coordinate system, and setting the density of the labeling point to be 1; and calculating a center-of-gravity position corresponding to each coordinate axis according to the density of all the labeling points on each coordinate axis, determining a target point based on all the center-of-gravity positio
