具体实施方式
本公开实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
参见图1,图1是本公开实施例提供的信息处理方法的流程图,如图1所示,包括以下步骤:
步骤101、获取目标用户的数据,其中,所述目标用户的数据包括健康数据、属性数据、评估数据以及所述目标用户在候选训练项目中的训练数据,所述目标用户的评估数据在第一预设时间段内的改善值大于0。
在本公开实施例中,可通过传感设备等采集用户的数据,例如包括:用户基本的健康数据,基本的属性数据,评估数据,在候选训练项目中的训练数据等。
其中,健康数据可包括:年龄段,性别,学历,体重,身高,血压,脉搏,睡眠,精神状态,情绪状态,跌倒经历,既往病症等;属性数据可包括:年龄,性别,学历,跌倒经历,既往病症等;评估数据包括通过简易精神状态量表(Mini Mental State Examination,MMSE)或者起立行走(Time Up Go, TUG)试验等评估方法获得的评估分数;在候选训练项目中的训练数据可包括利用脑成像仪等方式采集的大脑训练数据以及利用魔法垫等方式采集的身体活动训练数据。
其中,所述候选训练项目可根据需要设置,所述第一预设时间段也可根据需要设置。
对于采集用户的数据,利用历史数据统计方法,提取预设期间内(例如:短期:1个月,长期:3个月)评估数据的评分数值有改善效果的评估数据。其中,有改善的评估数据指的是,在预设时间内的最后一次MMSE/TUG的分数值和前一次MMSE/TUG的分数值之差大于0的评估数据。将这些有改善的评估数据所对应的用户作为目标用户,并提取这些目标用户的数据。通过这种方式,可使得获得的训练项目推荐模型更符合用户的需求。
步骤102、根据所述目标用户的数据形成训练项目推荐模型,其中,所述训练项目推荐模型利用评估数据的改善值最大的训练项目推荐路径生成。
在此步骤中,可根据所述目标用户的数据生成决策树模型,并利用所述决策树模型,获取目标项目推荐路径,其中,所述目标项目推荐路径包括评估数据的改善值最大的项目推荐路径。然后,根据所述目标项目推荐路径形成训练项目推荐模型。
在根据所述目标用户的数据生成决策树模型的过程中,基于目标用户的数据,利用信息熵算法对用户数据的特征进行影响度分析,选择对改善结果有影响的特征,特征选取完成后,生成决策树模型。
具体的,对于所述健康数据、所述属性数据以及所述训练数据中的每个特征,计算每个特征对应的信息增益比和阈值。对于同一类特征,将信息增益比最大的特征作为根节点,根据所述阈值将其他的特征进行树杈分支,形成决策树分支。然后,基于所有类别的特征所形成的决策树分支,形成所述决策树模型。通过这种方式,可生成一颗基于对改善结果影响重要度进行排序和分类的决策树模型。
此外,在形成决策树模型之后,还可删除所述决策树模型中信息增益比为0(也即对改善效果没影响)的决策树分支,从而提高处理效率。
在本公开实施例中,获取的目标路径可包括第一目标项目推荐路径,其 中,所述第一目标项目推荐路径对应的评估数据的改善值(效果)最大;还可以进一步包括第二目标项目推荐路径,其中,第二目标项目推荐路径中,用户在第二预设时间段内参与训练项目的天数(兴趣)最多;第三目标项目推荐路径中,用户在第二预设时间段内参与训练项目的次数(效率)最小。其中,该第二预设时间段可根据需要设置。
具体的,可利用后剪枝算法,从所述决策树模型中选取第一目标项目推荐路径,其中,所述第一目标项目推荐路径对应的评估数据的改善值最大。利用后剪枝算法,从所述第一目标项目推荐路径中选取第二目标项目推荐路径,以及,利用后剪枝算法,从所述第二目标项目推荐路径中选取第三目标项目推荐路径。也即,对同一类特征用户,利用决策树的后剪枝算法,保留效果最大的路径;从效果最大的路径中,保留兴趣最大的路径;从兴趣最大的路径中,保留效率最大路径。当然,在实际应用中,兴趣或者效果还可通过其他参数来体现。
在实际应用中,可根据第一目标项目推荐路径形成训练项目推荐模型,或者,还可根据第二目标项目推荐路径形成训练项目推荐模型,还可根据第三目标项目推荐路径形成训练项目推荐模型。
在获得了目标项目推荐路径后,可获取其中的训练天数,每个项目的训练次数等信息,利用用户的数据对该模型进行训练,从而可提高模型的准确性。
步骤103、获取待推荐用户的数据,其中,所述待推荐用户的数据包括健康数据、属性数据、评估数据。
其中,待推荐用户的健康数据可包括:年龄段,性别,学历,体重,身高,血压,脉搏,睡眠,精神状态,情绪状态,跌倒经历,既往病症等;属性数据可包括:年龄,性别,学历,跌倒经历,既往病症等;评估数据包括通过MMSE或者TUG等评估方法获得的评估分数。
步骤104、根据所述待推荐用户的数据以及所述训练项目推荐模型,为所述待推荐用户生成推荐训练项目。
在实际应用中,如果按照步骤101-102的过程生成了训练项目推荐模型,那么,在后期为用户推荐训练项目时,可无需再重新生成模型,而可直接利 用已经生成的训练项目推荐模型为用户推荐训练项目。
由于训练项目推荐模型是利用评估数据的改善值最大的训练项目推荐路径生成,也即该训练项目推荐路径对应的训练项目效果改善最好,因此,可使得通过该模型获得的推荐训练项目为对训练效果改善最好的训练项目,从而可满足用户对训练效果的要求。
参见图2,图2为根据本公开实施例的方案生成的决策树模型的示意图。其中,MMSE分数值改善最大的路径有3条,即分数值为2的三条路径。从这三条路径中,选择兴趣最大的路径即参与天数大于或等于3天的路径301;接着,在路径301中,选择参加游戏次数最少的路径(即路径最短,或称为效率最高)302。该路径302中的项目和用户特征可用作形成训练项目推荐模型。
参见图3,图3是本公开实施例的信息处理系统的结构示意图。如图3所示,该系统可包括传感设备,数据采集设备,训练项目推荐设备等。该系统和上述方法可应用于养老院等场所。
数据采集设备通过传感设备采集用户(比如老人)的数据,如基本数据,评估数据,训练数据等,该数据可同时存储到数据采集设备的数据库中。这些数据输入到训练项目推荐设备生成训练项目推荐模型。当需要为新的用户推荐训练项目时,采集该用户的基本数据,评估数据,并输入到训练项目推荐设备中,生成推荐训练项目。该推荐训练项目可提供给看护人员,并推荐给该新的用户。
参见图4,图4是本公开实施例提供的信息处理装置的结构图。由于信息处理装置解决问题的原理与本公开实施例中信息处理方法相似,因此该信息处理装置的实施可以参见方法的实施,重复之处不再赘述。
