Abstract: Disclosed is an automatic depression detection method using audio-video, including: acquiring original data containing two modalities of long-term audio file and long-term video file from an audio-video file; dividing the long-term audio file into several audio segments, and meanwhile dividing the long-term video file into a plurality of video segments; inputting each audio segment/each video segment into an audio feature extraction network/a video feature extraction network to obtain in-depth audio features/in-depth video features; calculating the in-depth audio features and the in-depth video features by using multi-head attention mechanism so as to obtain attention audio features and attention video features; aggregating the attention audio features and the attention video features into audio-video features; and inputting the audio-video features into a decision network to predict a depression level of an individual in the audio-video file.

Abstract: Embodiments of this application relate to the video coding and compression field, and disclose an encoding method and apparatus, and a decoding method and apparatus, to resolve a problem that an existing split mode cannot satisfy a relatively complex texture requirement. The decoding method specifically includes: parsing a bitstream to determine a basic split mode for a current to-be-decoded picture block and a target derivation mode for a subpicture block of the current to-be-decoded picture block; splitting the current to-be-decoded picture block into N subpicture blocks in the basic split mode, where N is an integer greater than or equal to 2; deriving one derived picture block from at least two adjacent subpicture blocks in the N subpicture blocks in the target derivation mode; and decoding the derived picture block.

Abstract: Disclosed are a heating core assembly and an air heating atomization device. The heating core assembly includes a preheating passage, a tobacco pot, a heating element and a filter assembly. The tobacco pot is divided into a first pot body and a second pot body. The second pot body is communicated with the preheating passage. The heating element is arranged in the preheating passage. The filter assembly is removably installed in the second pot body and can be pushed into the second pot body again through the first pot body after being removed. During smoking, external air flow enters the preheating passage, and then the preheating passage discharges hot air to the second pot body, such that heat is uniformly sent into the first pot body to evaporate substance to be evaporated after passing through the filter assembly. Such design can improve air preheating efficiency while ensuring convenient cleaning.
