Abstract: The present disclosure provides a method for configuring a learning model for music generation and the corresponding learning model. The method includes training a masked autoencoder with training data comprising a combination of a reconstruction loss over time and frequency domains and a patch-based adversarial objective operating at different resolutions. An omnidirectional latent diffusion model is trained based on music data represented in a latent space to obtain a pretrained diffusion model. The pretrained diffusion model is fine-tuned based on text-guided music generation, bidirectional music in-painting, and unidirectional music continuation. The method enables high-fidelity music generation conditioned on text or music representations while maintaining computational efficiency.

The clamping mechanism (320) is disposed at a distal end of the body (310), and the body (310) extends from the first proximal end to the first distal end. The clamping mechanism (320) limits relative movement and thus prevents tangling of the protrusions (111) by passing through all or some of the protrusions (111).
