The present invention provides a method, device, electronic device, and storage medium for training a cheat recognition model. The method includes: determining the training samples of the cheat recognition model based on the behavior information of the target user, and determining the characteristics of the cheat portrait in the cheat recognition environment. ; According to the behavior information of the target user, determine the corresponding behavior sequence information; determine the model parameters that are compatible with the plug-in identification model, so that the behavior of the target user can be monitored in real time through the plug-in identification model, and According to the risk prediction results, the matching event execution strategy is executed, which makes the generalization ability and data processing ability of the cheat recognition model stronger, adapts to different cheat recognition environments, and reduces the robustness of the cheat recognition model. At the same time, there is no need to obtain a large number of labeled samples to train a model dedicated to identifying cheating behaviors, so the cost of identifying cheating behaviors can be effectively reduced.

The invention discloses an intelligent billiards referee anti-cheating method and system, comprising: acquiring the batter's batting parameters, and calculating the batting energy value according to the batting parameters; after the batter finishes hitting the ball, acquiring Continuous frame images of the table and billiards on the table; analyzing the continuous frame images to obtain the movement trajectory of each billiard ball; obtaining the corresponding energy loss value of each billiard ball according to the movement trajectory of each billiard ball; calculating the energy consumption of all billiard balls value, judging whether the sum of the energy loss values ​​is greater than the energy value of hitting the ball, and if it is determined that the sum of the energy loss values ​​is greater than the energy value of hitting the ball, it indicates that there is cheating. According to the relationship between the energy value of hitting the ball and the energy loss value of the billiard ball after hitting the ball, it is accurately judged whether the player is cheating.

The invention relates to the field of network education technology, and particularly to an intelligent cheating preventing method and a device thereof, wherein the method comprises the steps of acquiring position distribution of intelligent devices by a server, and further determining n intelligent devices with a cheating risk around a random intelligent device A; distributing examination questions to each intelligent device by a server according to different sequences so that each intelligent device successively displays the problems according to a distributed sequence; and dynamically adjusting the displaying sequence of the questions on each intelligent device by the server based on the question answering progress of each examinee, so that the current displaying questions on a random intelligent device in the n intelligent devices and the intelligent device A are different. According to the method and the device, not only can the examination questions be distributed to the intelligent devices according to different sequences in advance, but also the question sequence is dynamically adjusted according to the question answering progress in an examination process so that displayingof the same question on the screens of adjacent examinees at the same time is prevented, thereby reducing cheating behaviors.
