This disclosure provides an entity classification method, apparatus, electronic device, and storage medium. The method includes: acquiring multiple entity relationship networks corresponding to multiple entity nodes; the same entity node corresponding to different entity relationships in different entity relationship networks; performing multi-label prediction on the multiple entity relationship networks based on multiple trained base learners to obtain the multi-label prediction result of each entity node in each entity relationship network; and determining the final multi-label prediction result corresponding to each entity node based on the multi-label prediction result of each entity node in each entity relationship network. This disclosure, from the perspective of multi-view learning, performs multi-label prediction based on multiple entity relationship networks, which can more fully explore the relationships between entities, making the multi-label prediction results for entity nodes more accurate.

This disclosure provides a microphone array noise reduction method, apparatus, system, electronic device, and storage medium. The method includes: acquiring an audio signal to be denoised; performing frequency domain processing on the audio signal to obtain a frequency domain signal; responding to a first sub-frequency domain signal with a frequency less than a preset threshold in the frequency domain signal, performing a first noise reduction process based on a pre-set subtractive microphone array to obtain a denoised first sub-frequency domain signal; responding to a second sub-frequency domain signal with a frequency greater than or equal to a preset threshold in the frequency domain signal, performing a second noise reduction process based on a pre-set additive microphone array to obtain a denoised second sub-frequency domain signal; and obtaining a denoised audio signal based on the denoised first and second sub-frequency domain signals. This disclosure combines the superior characteristics of subtractive and additive microphone arrays to perform targeted noise reduction processing on low-frequency and high-frequency signals respectively, resulting in better noise reduction performance.
