针对基于高光谱数据的悬浮物浓度反演问题,提出一种利用预训练神经网络(PNN)进行有监督波段选择的方法,并使用随机森林和神经网络建立悬浮物浓度反演模型。PNN算法需进行多次重复实验以获得低噪声且充分的波段重要性表达,在每次实验时选取适当数量的波段作为神经网络输入数据的特征,训练一个神经网络,并利用最后一期训练时第一层权重的L1范数、L2范数和ReLU(Rectified Linear Unit)函数来表示波段的重要性。实验结果表明,相比其他常用的波段选择算法,使用L1范数、L2范数的PNN算法能够得到信息量更大的波段集合,且其用于悬浮物浓度反演时,能够获得更优的效果。

Two-dimensional materials represent a major frontier for research into exotic many-body quantum phenomena. In the extreme two-dimensional limit, electron-electron interaction often dominates over other electronic energy scales, leading to strongly correlated effects such as quantum spin liquid and unconventional *** dominance is conventionally attributed to the lack of electron screening in the third dimension. Here, we discover an intriguing metal to Mott insulator transition in 1T-TaSe2that defies conventional wisdom. Specifically, we find that dimensionality crossover, instead of reduced screening, drives the transition in atomically thin 1T-TaSe2. A dispersive band crossing the Fermi level is found to be responsible for the bulk metallicity in the material. Reducing the dimensionality,however, effectively quenches the kinetic energy of these initially itinerant electrons, and drives the material into a Mott insulating *** dimensionality-driven metal to Mott insulator transition resolves the long-standing dichotomy between metallic bulk and insulating surface of 1T-TaSe2. Our work further reveals a new pathway for modulating two-dimensional materials that enables exploring strongly correlated systems across uncharted parameter space.
