Embodiment approach
[0041] Wherein, the ratio of each bucket can be set in advance, for example, the ratio is the ratio of the total number of negative samples to the number of positive samples in the bucket. In one embodiment, the process of sampling the sample data corresponding to the proportion of the bucket from each bucket may be: calculating the average value of the loss value of the positive sample data in each bucket; for each bucket, calculating the The ratio of the average value of the bucket to the sum of the average values of all buckets, and calculate the product of the ratio and the negative sample data, and sample the sample data corresponding to the product from the bucket. In this implementation, the preset ratio of the i-th bucket can be expressed as: in, is the average of the loss values of all positive sample data in the i-th bucket, and p is the number of disks in the negative sample data. If the average value of the loss value of the positive sample data in the buck...
