Data analysis in SERS diagnostics
SERS for Point-Of-care and Clinical Applications（2022）
Abstract
Surface-enhanced Raman spectroscopy (SERS) datasets obtained from biomedical samples are rich in information, but this wealth of information is not always easy to get. Extracting the right information from this complexity is a challenging task. Preprocessing procedures and multivariate analysis methods are extremely powerful tools to help us in this task. These tools, however, are as powerful as dangerous, if not correctly used, and can easily lead to wrong conclusions. This chapter is a short introduction into the analysis and interpretation of SERS spectral data in biomedical studies. The aim is to give practical advices to the researcher through a quick overview of the most relevant techniques for data visualization and analysis, with an emphasis on both their capabilities and weaknesses.

- 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
