Abstract

In order to overcome the problems existing in traditional financial risk evaluation methods, such as high generalization error and fitting degree with actual value, this paper designs a financial risk evaluation method of blockchain digital currency based on CART algorithm. After screening and ranking the financial risk indicators of blockchain digital currency, the financial risk level of blockchain digital currency is determined by combining CART algorithm. Finally, by calculating the covariance matrix of the financial risk decision matrix, the positive ideal solution and the negative ideal solution of the financial risk are found, and then the final evaluation result is obtained by combining the progress of the financial risk. Experimental results show that the minimum generalization error of this method is only 0.021, the fitting degree of the obtained results and the actual risk can reach 98.0%, and the maximum risk accuracy can reach 0.978.
基于CART算法的区块链数字货币财务风险评估方法
为了克服传统金融风险评价方法存在的泛化误差大、与实际值拟合程度高等问题,本文设计了一种基于CART算法的区块链数字货币金融风险评价方法。对区块链数字货币的财务风险指标进行筛选排序后,结合CART算法确定区块链数字货币的财务风险等级。最后,通过计算财务风险决策矩阵的协方差矩阵,找到财务风险的正理想解和负理想解,然后结合财务风险的进展得到最终的评价结果。实验结果表明,该方法的最小概化误差仅为0.021,所得结果与实际风险的拟合程度可达98.0%,最大风险准确率可达0.978。
