Abstract

Credit assessment models are an important basis for financial credit institutions to determine whether to lend or not, so an efficient and accurate credit assessment model is crucial for financial credit institutions. Traditional credit assessment algorithms do not take into account the noise problem caused by the massive amount of credit data, which greatly affects the time complexity and accuracy of credit assessment algorithms. In view of this, this paper proposes a credit assessment method based on information entropy and LSSVM. The method first uses information entropy to assign weights to feature attributes, then sets thresholds on them for feature extraction, and constructs an LSSVM model to evaluate credit data, so as to achieve accurate assessment of credit transaction risk. The experimental results show that the method can effectively reduce the time complexity of the algorithm and improve the accuracy of prediction
基于信息熵和LSSVM的信用评估模型研究
信用评估模型是金融信贷机构决定是否发放贷款的重要依据,因此一个高效、准确的信用评估模型对金融信贷机构至关重要。传统的信用评估算法没有考虑海量信用数据带来的噪声问题,极大地影响了信用评估算法的时间复杂度和准确性。鉴于此,本文提出了一种基于信息熵和LSSVM的信用评估方法。该方法首先利用信息熵对特征属性赋予权重,然后对特征属性设置阈值进行特征提取,并构建LSSVM模型对信用数据进行评估,从而实现对信用交易风险的准确评估。实验结果表明,该方法能有效降低算法的时间复杂度,提高预测精度
