The present disclosure provides a composite material and a preparation method thereof, and a light-emitting device. The composite material includes inorganic nanoparticles and a polymer, the polymer is attached to the inorganic nanoparticles, and the polymer contains a porphyrin group. Since the polymer has the property of isolating water and oxygen, when the polymer is attached to the inorganic nanoparticle, the influence of external water and oxygen on the inorganic nanoparticle may be weakened or eliminated, so that the electrical properties of the inorganic nanoparticle remain stable. Since the porphyrin group in the polymer has conductive properties, the electron transport efficiency of the composite material may be improved.

A system and method for video temporal action proposal generation are provided. It processes video features extracted from the input video through an encoder to obtain video encoding features with global information, extracts corresponding interest segment features from the video encoding features using pre-trained proposal segments, and provides them to the decoder. The decoder generates segment features based on the interest segment features corresponding to each proposal segment and the pre-trained proposal features. These are then provided to the prediction module, generating temporal action proposal results based on the decoder's segment features. The solution in embodiments of the present invention can effectively capture global context information of the video, obtaining video encoding features with stronger representational capabilities; By introducing the several learnable proposal segments to extract the corresponding position-based feature sequences from the video encoding features, the training convergence speed is enhanced, and computational burden is reduced.
