Abstract
Rapid and economical classification of transgenic soybean and non-transgenic soybean is highly important for food processing and handling. This paper developed an efficient and low-cost identification method for different categories of soybeans on the basis of a handheld miniature near-infrared spectrometer. The dataset consists of transgenic modified and non-transgenic soybeans from soybean breeders, and different pretreatment methods and classifiers are used to establish models. The identification model with the best performance is selected for the boosting models. After the data are compared by different pretreatment methods and classifiers, SG+SNV is the best, and the performance of the model constructed by the gradient lifting tree is optimized. The accuracy is 98.03 % and the F1 score is 96.74 %. The results show that the near-infrared spectrum can be used to collect the all-band spectrum of soybean, and the model can be used to classify the soybean category accurately, and quickly via a handheld miniature spectrometer.

- 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
