Multi-way Spectral Analysis Methods Based on Support Tensor Machines
The powerful ability of generating multi-way spectral data in modern spectrum instruments makes multi-way spectral quantitative analysis method become one of the important topics. Since the multi-way spectrometry is represented as a tensor
a new multi-way spectral quantitative analysis method based on support tensor machines (STM) is presented. The presented methods preserve the intrinsic structure of the multi-way spectrometry. Due to the reduction of model parameter number
the methods represented by tensor reduce the over-fit problem in the case of small samples. Unlike the conventional methods such as parallel factor analysis (PARAFAC) and multi-way partial least squares (N-PLS)
the presented methods do not need to estimate the component number. The experiments for detecting chemical oxygen demand (COD) and total organic carbon (TOC) in water are carried out. The experimental results show that the presented methods are improved with comparison to the existing multi-way spectral quantitative analysis methods
and the models are not sensitive to the pre-determined parameters
