Abstract: A nitride semiconductor light-emitting element includes an active layer comprising at least one well layer, a p-type semiconductor layer located on one side of the active layer, and an electron blocking stack body located between the active layer and the p-type semiconductor layer. The electron blocking stack body includes a first electron blocking layer and a second electron blocking layer that is located on the p-type semiconductor layer side relative to the first electron blocking layer and has a lower Al composition ratio than that of the first electron blocking layer. When a total number of the well layers in the active layer is N, a film thickness of the first electron blocking layer is a film thickness d [nm] and an Al composition ratio of the second electron blocking layer is an Al composition ratio x [%], relationships 0.1N+0.9?d?0.2N+2.0 and 10N+40?x?10N+60 are satisfied.

Abstract: Disclosed is a method for training an abnormal-detection model based on an improved denoising autoencoder, including: acquiring an original image; generating a rectangular frame according to a preset range of a resolution ratio, by the improved denoising autoencoder, and occluding the original image by the rectangular frame, wherein the resolution ratio is a ratio of a resolution of an occlusion area formed by the rectangular frame to a resolution of the original image; filling random noise in the rectangular frame to obtain a noised image, by the improved denoising autoencoder; and performing constraint learning on the original image and the noised image, by the abnormal-detection model, to implement training of the abnormal-detection model. Because a learning task is more complex, it is helpful to alleviate identity mapping, and detection performance of the model is improved. The present application further provides an apparatus, a device, and a readable storage medium thereof.
Abstract: The present disclosure discloses an interface display method and apparatus, a computer device, and a storage medium, and the interface display method is applied to a first client and includes: during a first period when a livestreaming room is in a preset state, in response to receiving an interaction trigger operation for the livestreaming room, determining, according to the interaction trigger operation, target interaction information corresponding to the preset state, the target interaction information being different from actual interaction information corresponding to the interaction trigger operation; and based on the target interaction information, generating an interaction effect corresponding to the preset state, and displaying the interaction effect.
