在进行转换时,我们将力争符合(有时需要最小限度的扩展)主流行业参考模型和标准(如 ACCORD、Xretail 等)。
When we conduct the transformation, we will strive to adhere, or sometimes with minimal extension, the prevaling industry reference models and standards (such as ACCORD, IXRetail, etc.).
在这种模型框架下,给出加权最小平均损失来测度风险的标准,于是问题转化为风险控制问题。
In the context of our model, we propose measuring risk as smallest expected weighted loss. Thus, the above-mentioned is transformed into one of risk control problems.
