This AI Paper Proposes A Self-Supervised Music Understanding Model Called MERT That Attains Overall SOTA Performance on 14 MIR Tasks

Self-supervised learning is being prominently utilized in Artificial Intelligence to develop intelligent systems. The transformer models like BERT and T5 have recently got popular resulting from their excellent properties and have utilized the thought of self-supervision in Natural Language Processing tasks. These models are first trained with massive amounts of unlabeled data, then fine-tuned with labeled data samples. Though Self-supervised learning has been successfully utilized in a variety of fields, including speech processing, Computer vision, and Natural Language Processing, its application still must be explored in music audios. The explanation for that’s the constraints accompanying the sphere of music, which is modeling musical knowledge just like the tonal and pitched characteristics of music.

To handle this issue, a team of researchers has introduced MERT, which is an abbreviation for ‘Music undERstanding model with large-scale self-supervised Training.’ This acoustic model has been developed with the thought of using teacher models to generate pseudo labels in the way of masked language modeling (MLM) for the pre-training phase. MERT helps the transformer encoder within the BERT approach, which is the coed model, to understand and understand the model music audio in a greater way by integrating the teacher models.

This generalizable and inexpensive pre-trained acoustic music model follows a speech Self Supervised Learning paradigm and employs teacher models to generate pseudo targets for sequential audio clips by incorporating a multi-task paradigm to balance acoustic and musical representation learning. To reinforce the robustness of the learned representations, MERT has introduced an in-batch noise mixture augmentation technique. By combining audio recordings with random clips, this system distorts the audio recordings, difficult the model to choose up relevant meanings even from obscure circumstances. The model’s capability to generalize to situations where music could also be mixed with irrelevant audio is enhanced by this addition.

The team has give you a brilliant effective combination of teacher models that shows higher performance than all the traditional audio and speech methods. This group includes an acoustic teacher based on Residual Vector Quantization – Variational AutoEncoder (RVQ-VAE) and a music teacher based on the Constant-Q Transform (CQT). The acoustic teacher utilizes RVQ-VAE to offer a discretized acoustic-level summarization of the music signal, capturing the acoustic characteristics. Based on CQT, the musical teacher focuses on capturing the tonal and pitched elements of the music. Together, these teachers guide the coed model to learn meaningful representations of music audio.

The team has also explored settings to deal with acoustic language model pre-training instability. By optimizing these settings, they were in a position to scale up MERT from 95M to 330M parameters, leading to a more powerful model able to capturing intricate details of music audio. Upon evaluation, the experimental results demonstrated the effectiveness of MERT in generalizing to varied music understanding tasks. The model achieved SOTA scores on 14 different tasks, showcasing its strong performance and generalization ability. 

In conclusion, the MERT model addresses the gap in applying Self Supervised Learning to music audios.
