A data denoising method and a related device. According to the method, artificial intelligence technology can be used for denoising data, and any target denoising operation of at least one denoising operation, which is executed on noisy data, comprises: according to first prediction information and second prediction information, generating distribution information corresponding to the target denoising operation, wherein the first prediction information indicates predicted noise of second noisy data with respect to clean data, and the second prediction information indicates the square of the predicted noise of the second noisy data with respect to the clean data, or indicates the square of a predicted distance between the first prediction information and actual noise, and the actual noise comprises actual noise of the second noisy data with respect to the clean data; and sampling denoised data from a distribution space to which the distribution information points. Since distribution information corresponding to a denoising operation is not directly learned, the number of times that the denoising operation is executed on noisy data is not constrained by a training stage, thereby improving the flexibility of a reasoning stage.
