对于S1，可以获取用户发送的信用卡客户价值确定请求，也可以是应用系统发送的信用卡客户价值确定请求。
信用卡客户价值确定请求，是指确定信用卡客户的客户潜在价值的请求。
目标历史交易数据，是以当前时间为结束时间第一预设时长内的信用卡客户的历史信用卡交易数据。
历史信用卡交易数据，也就是信用卡交易数据。信用卡交易数据包括但不限于：业务类别、交易金额、交易时间。
业务类别包括：基础消费、个人分期、商户分期、提取现金。基础消费，是信用卡客户在商户分期以外的刷卡消费。个人分期包括：账单分期、取现分期。商户分期，是指为商户商品定制的分期，信用卡客户购买该商户的商品时选择了分期的刷卡消费。提取现金，是信用卡客户将信用额度提取现金但是没有将提取的现金选择分期的消费。
对于S2，将所述目标历史交易数据依次进行业务类别划分和生命周期匹配，得到多个待分析历史交易数据，也就是说，同一待分析历史交易数据中的数据属于相同业务类别和相同生命周期。
所述各自对应的目标业务类别及目标生命周期，是指多个待分析历史交易数据各自对应的目标业务类别及目标生命周期。
将划分待分析历史交易数据所用的业务类别作为待分析历史交易数据对应的目标业务类别。将划分待分析历史交易数据所处的生命周期作为待分析历史交易数据对应的目标生命周期。
生命周期，是指信用卡客户的生命周期阶段。生命周期包括：获客期、接触期、成长期、成熟期、衰退期、沉默期，可以理解的是，生命周期还可以有其他划分方式和命名方式，在此不做具体限定。
客户状态包括：距今消费时长、消费频次、消费金额。距今消费时长包括：首次消费的距今消费时长、最后一次消费的距今消费时长。消费频次是指以当前时间为结束时间第二预设时长内的消费次数。
对于S3，依次从多个待分析历史交易数据中提取出待分析历史交易数据；根据提取出的所述待分析历史交易数据对应的所述目标业务类别和所述目标生命周期从数据库中获取客户价值均值数据，将获取的客户价值均值数据作为提取出的待分析历史交易数据的目标客户价值均值数据；重复上述步骤直至确定所有所述待分析历史交易数据的目标客户价值均值数据。
目标客户价值均值数据，也就是客户价值均值数据。客户价值均值数据是个 时间序列。也就是说，客户价值均值数据，是同一个业务类别和同一个生命周期的信用卡客户的客户价值的平均值。
客户价值均值数据包括但不限于：信用卡客户毛利润均值数据、信用卡客户净利润均值数据。
对于S4，采用马尔科夫决策过程分别根据每个所述待分析历史交易数据和各自对应的所述目标客户价值均值数据进行效用函数提取，得到多个效用函数集合；然后采用最大似然逆强化学习分别对每个所述效用函数集合进行进行参数估计，得到每个所述待分析历史交易数据的目标状态转移概率矩阵。每个所述待分析历史交易数据对应一个目标状态转移概率矩阵。
目标状态转移概率矩阵，也就是状态转移概率矩阵。状态转移概率矩阵，是客户状态转移的概率的矩阵。
对于S5，分别将每个所述待分析历史交易数据的目标状态转移概率矩阵和各自对应的所述目标客户价值均值数据进行相乘计算，得到多个待分析客户价值矩阵；分别将每个所述待分析客户价值矩阵的元素值进行求和计算，得到所述多个目标细分类客户价值数据。也就是说，每个所述待分析历史交易数据对应一个所述目标细分类客户价值数据。
比如，目标状态转移概率矩阵表述为：
Figure PCTCN2021096978-appb-000001
目标客户价值均值数据G为：[G1G2G3G4G5]，目标状态转移概率矩阵和目标客户价值均值数据相乘，将P和G相乘得到矩阵J，将矩阵J中所有元素的元素值进行求和计算，将计算结果作为目标细分类客户价值数据，在此举例不做具体限定。
目标细分类客户价值数据，就是目标历史交易数据对应的信用卡客户在目标业务类别在目标生命周期的客户价值。也就是说，目标细分类客户价值数据的数量和业务类别的数量相同。
对于S6，可选的，将所述多个目标细分类客户价值数据按时间形成矩阵将该矩阵也就是信用卡客户的用户画像，将该信用卡客户的用户画像作为目标用户画像。
目标用户画像，用于描述所述信用卡客户价值确定请求对应的信用卡客户在信用卡各业务类别的在时间点是否进行消费及消费带来的预期客户价值。
当客户价值均值数据是信用卡客户毛利润均值数据时，消费带来的预期客户价值是指毛利润数值；当客户价值均值数据是信用卡客户净利润均值数据时，消费带来的预期客户价值是指净利润数值。
比如，当客户价值均值数据是信用卡客户毛利润均值数据时，目标用户画像可以表述为：
Figure PCTCN2021096978-appb-000002
其中，第一行表述目标业务类别为基础消费，第二行表述目标业务类别为个人分期，第三行表述目标业务类别为商户分期，第四行表述目标业务类别为提取现金，第一列表述第一时间、第二列表述第二时间、第三列表述第三时间、第四列表述第四时间；
目标用户画像的第一时间表述在个人分期和提取现金将进行消费，在第一时间针对该信用卡客户应该将精准营销定位在个人分期和提取现金，又由于个人分期带来的预期客户价值500元大于提取现金带来的预期客户价值100元，需要进一步将精准营销定位在个人分期；
目标用户画像的第三时间表述该信用卡客户不会进行消费，在第三时间将不需要对该信用卡客户进行精准营销，在此举例不做具体限定。
在一个实施例中，上述将所述目标历史交易数据进行业务类别划分和生命周期匹配，确定多个待分析历史交易数据和各自对应的目标业务类别及目标生命周期的步骤，包括：

S23：采用所述生命周期划分标准数据分别根据每个所述待分析历史交易数据的距今消费时长、消费频次、消费金额、所述目标业务类别进行生命周期匹配，得到每个所述待分析历史交易数据对应的目标生命周期。
本实施例实现了先按业务类别和生命周期对所述目标历史交易数据进行划分，生命周期是根据待分析历史交易数据和目标业务类别确定的，充分考虑了业务类别、生命周期、历史交易数据，为后续确定目标细分类客户价值数据提供了数据基础。

比如，业务类别包括：基础消费、个人分期、商户分期、提取现金，生命周期包括：获客期、接触期、成长期、成熟期、衰退期、沉默期，信用卡客户A的目标历史交易数据采用所述业务类别进行划分，得到基础消费的历史交易数据为A1、个人分期的历史交易数据为A2、商户分期的历史交易数据为A3、提取现金的历史交易数据为A4，根据A1的距今消费时长、消费频次、消费金额进行生命周期划分得到A1的目标生命周期为成熟期，根据A2的距今消费时长、消费频次、消费金额进行生命周期划分得到A2的目标生命周期为成长期，根据A3的距今消费时长、消费频次、消费金额进行生命周期划分得到A3的目标生命周期为接触期，根据A4的距今消费时长、消费频次、消费金额进行生命周期划分 得到A4的目标生命周期为接触期，在此举例不做具体限定。

对于S31，依次从所述多个待分析历史交易数据中提取出一个所述待分析历史交易数据的所有数据。
