大小盘风格轮动策略,本版本暂时选取沪深300作为大盘股指数，中小板指数作为小盘股指数(Size of the disk style rotation strategy, the release time being selected as the CSI 300 index of large-cap stocks, small board index as the small cap index)

Compute log(sum(exp(x),dim)) while avoiding numerical underflow. By default dim = 1 (columns).

带有级比调整的灰色预测代码 在灰色预测之前做级比检验，降低相对误差(GREY MODEL)

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)

Visual Cryptography is based on cryptography where n images are encoded in a way that only the human visual system can decrypt the hidden message without any cryptographic computations when all shares are stacked together. This paper presents an improved algorithm based on Chang’s and Yu visual cryptography scheme for hiding a colored image into multiple colored cover images. This scheme achieves lossless recovery and reduces the noise in the cover images without adding any computational complexity.
