    Abstract
    Wheel/rail rolling noise is considered to be one of the most important sources of railway noise, even for high-speed railways. In order to accurately predict wheel-rail noise, representative prediction program has been developed and applied. The authors have also developed a wheel/rail rolling noise prediction program, taking more account of characteristics of high-speed slab railway tracks, having sufficient computational efficiency to handle engineering problems. This paper introduces the calculation methods, operation mechanism and characteristics of this program. Typical results are given and compared with measurement.

    • 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
