Abstract
The cries of infants contain rich information, indicating hunger, tiredness, discomfort, and other physical discomforts. If we can understand a baby's cry, we can quickly assess their state and take appropriate action. The classification of infant cry sounds plays a crucial role in areas such as household prompts and medical examinations. However, the diversity and complexity of infant cry categories present significant challenges for deep classification design. To improve classification accuracy while conserving computational resources, this study proposes a classification method based on a multi-scale convolutional attention neural network with residual downsampling. The proposed model consists of four parts: a feature extraction module, SE attention module, residual downsampling module based on residual networks, and multi-scale convolution module. Mel spectrogram transformation is applied to the audio to extract feature information, and downsampling is performed to obtain richer feature representations. The combination of multi-scale convolution and attention is used to extract key information from the features. The proposed model achieves an accuracy of 86.29% on publicly available datasets. The model parameters of the proposed algorithm amount to 6.67 million, with a computational cost of 0.66G FLOPs per second. Compared to other existing deep learning algorithms, the proposed model achieves the highest accuracy while considering both the parameter quantity and computational cost simultaneously.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
