Prediction method and device of disease complications, computer equipment and storage medium

The invention relates to the technical field of artificial intelligence, and provides a disease complication prediction method and device, computer equipment and a storage medium, and the method comprises the steps: scanning a preset disease transaction database, and calculating a first weight of a disease item in the disease transaction database; calculating a second weight of the disease transaction based on the first weight of the disease item; calculating a first support count for the disease item based on the second weight of the disease transaction; screening disease frequent items of all disease affairs; generating an FP-tree based on the disease frequent items; calculating a second support degree count of a disease item set extracted from the FP-tree, and screening a disease frequent item set based on a support degree count threshold; and based on the disease frequent item set contained in the FP-tree and a preset confidence threshold, mining complications corresponding to diseases belonging to the di
