Research on the application of situation form judgment in command training based on K nearest neighbor data mining algorithm

Based on k nearest neighbor algorithm, this paper discusses the training method of assistant commander to judge the situation in command training, and focuses on judging the situation level of a certain area in a specific event. Firstly, KNN model is introduced. Then, after understanding the principle of the algorithm, python tool is used to calculate, classify and visualize the test samples of 13 regions. Finally, according to the distance between the test sample and the test sample, the level ' risk ' of the test area X is calculated, and then a reference training method is proposed for the training of decision-making ability in command training to assist command training.
