日本银行业在上世纪90年代爆发不良债权问题,由于初期的忽视和处理的拖延,导致日本陷入长期的景气收缩,物价下行,银行惜贷,货币政策和财政政策难以施力。在实施全额存款保险、成立资产管理公司、注入公共资金,量化宽松政策、金融再生计划等一系列特别措施后,最终走出不良债权问题的阴影。当前我国不良债权比率骤升,同时,经济面临景气下行和通缩压力,日本处理不良债权的经验及教训值得我们重新思考和研究。

The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2.

高光谱图像分类是图像解译任务的重要技术之一,已经在遥感观测、智慧医疗等诸多领域得到广泛的应用。本质上,高光谱图像分类由特征提取与基于分类器的标签预测这两阶段操作组成。现有分类方法在特征提取时,大多不考虑分类器的影响,会导致提取的特征与所用分类器之间的兼容性较差,难免出现预测结果差的情况。针对此问题,本文提出具有分类器机制的高光谱图像特征提取方法,保证特征提取与分类器之间的兼容性,使特征能更易于被分类器准确计算,改善分类预测结果。本文给出了两种具有分类器机制的高光谱图像特征提取模型的形式:(1)以稀疏表示和支持向量机为例,将支持向量机特性集成到稀疏表示形式中,建立了能够与支持向量机分类器相兼容的SRS特征提取模型;(2)以深度自编码网络与softmax函数为例,将softmax分类器特性嵌入到深度自编码网络中,构建能与softmax分类器相兼容的DAES特征提取模型。为获得SRS和DAES模型的解,本文还给出了对应的求解策略与优化过程。在遥感高光谱图像和医学高光谱图像数据上开展实验验证,结果表明,本文SRS和DAES算法具有明显的有效性和优越性,在高光谱图像分类指标OA (Overall Accuracy)、AA (Average Accuracy)、Kappa上分别提升约5.03%、5.13%、7.30%。
