Description

一种人工智能评估人才方法
技术领域
本发明涉及评价方法,尤其涉及一种人工智能评估人才方法。
背景技术
目前用人单位与求职者大多是通过现场或者视频会议的方式进行面试。
现有的招聘类产品与服务,一直沿袭着粗放式的信息(简历等)分发的状况,其中存在人的驱利本能所无法规避的问题:
(1)候选人在简历中有意隐瞒缺点或作假;同时也普遍存在着无意的作假,即由于候选人的自我认知偏差而导致的自我评价失真;
(2)很多高端岗位是异地面试,因面谈而产生的成本较高。
(3)现场面试需要用人单位和求职者同时有足够的时间才能够完成,占用彼此的时间。视频面试虽然可以足不出户利用连通了互联网的电脑,通过视频摄像头和耳麦进语音、视频、文字的方式进行即时沟通交流,但还是需要约定好同一时间,浪费人力和时间。
(4)不同的面试官,对问题会有不同的评价,同一面试官,因为不同的职场经验、面试技能和面试现场的认知状态下也会有不同的判断。另外虽然从国际人力资源以及人才管理领域引入的competency(国内翻译为胜任力、素质、能力)的概念,但从不同的翻译与缺乏知识系统的应用来看,产生非常多的不同的评估标准自然在所难免,最终导致评估效果的不确定性以及不利于持续的科学研究。
因此,如何提供一种人工智能评估人才方法,可以实现人工智能面试代替人工初次面试,能够对候选人进行多维度评价是本领域技术人员所亟待解决的技术问题。
发明内容
为了解决现有技术中的问题,本发明提供了一种人工智能评估人才方法。
本发明提供了一种人工智能评估人才方法,包括以下步骤:
首先,将分好词的问题q以及答案a利用词典映射成编码,利用embedding层将编码转换为特征矩阵
ea=wemb·ca (1)
eq=wemb·cq (2)
wemb为embedding层可训练的权重矩阵,ca表示编码后的答案向量,cq表示编码后的问题向量,dw为转换后每个词向量的长度,n为序列长度;在训练过程中特征矩阵会获得词级别的特征,获取到ea和eq后,使其经过双向LSTM层,LSTM指长短记忆网络,捕捉到整个句子的信息
ft=σ(wf·[ht-1,xt]+bf) (3)
it=σ(wi·[ht-1,xt]+bi) (4)
ot=σ(wo·[ht-1,xt]+bo) (7)
ht=ot×tanh(ct) (8)
r=[h1,h2,...,hn] (9)
wf,wi,wc,wo为可训练的权重矩阵,bf,bi,bc,bo为可训练的偏置向量,σ为sigmoid函数,dr为单向LSTM层隐藏状态的向量长度,xt为序列级别的特征输入,ft为遗忘门,it为输入门,ot为输出门,ct是细胞,ht为隐层状态;
其次,获取到答案和问题的句子表示ra,rq后,计算以答案为主的attention权重
将答案的句子表示ra与watt做数乘,对每行求平均值,生成包含问题和答案信息的全局表示
最后,h经过全连接层FCN得到答案的评分
I=avg(watt×ra) (11)
s=ws·l+bs (12)
其中,ws为可训练的权重矩阵,bs为可训练的偏置向量。
本发明的有益效果是:通过上述方案,可以实现人工智能面试代替人工初次面试,能够对候选人进行多维度评价,提高了面试效率和效果,降低了面试成本。
附图说明
图1是本发明一种人工智能评估人才方法的LSTM内部计算单元结构示意图。
图2是本发明一种人工智能评估人才方法的算法工作流程图。
具体实施方式
下面结合附图说明及具体实施方式对本发明作进一步说明。
如图1至图2所示,一种人工智能评估人才方法,利用深度学习相关方法,抽取问题和答案的高阶特征,并利用这些特征对答案进行打分,具体包括以下步骤:
首先,将分好词的问题q以及答案a利用词典映射成编码,利用embedding层将编码转换为特征矩阵
ea=wemb·ca (1)
eq=wemb·cq (2)
wemb为embedding层可训练的权重矩阵,ca表示编码后的答案向量,cq为编码后的问题向量,dw为转换后每个词向量的长度,n为序列长度;在训练过程中特征矩阵会获得词级别的特征,获取到ea和eq后,使其经过双向LSTM层,LSTM指长短记忆网络,捕捉到整个句子的信息
ft=σ(wf·[ht-1,xt]+bf) (3)
it=σ(wi·[ht-1,xt]+bi) (4)
ot=σ(wo·[ht-1,xt]+bo) (7)
ht=ot×tanh(ct) (8)
r=[h1,h2,…,hn] (9)
wf,wi,wc,wo为可训练的权重矩阵,bf,bi,bc,bo为可训练的偏置向量,σ为sigmoid函数,dr为单向LSTM层隐藏状态的向量长度,xt为序列级别的特征输入,ft为遗忘门,it为输入门,ot为输出门,ct是细胞,ht为隐层状态;
其次,获取到答案和问题的句子表示ra,rq后,计算以答案为主的attention权重
将答案的句子表示ra与watt做数乘,对每行求平均值,生成包含问题和答案信息的全局表示
最后,隐层输出向量h经过全连接层FCN得到答案的评分
I=avg(watt×ra) (11)
s=ws·l+bs (12)
其中,ws为可训练的权重矩阵,bs为可训练的偏置向量
为了更好的实现本发明,提高人工智能评估人才方法的效果,本发明还包括了由以下几个关键概念模型构建而成的Talent DNA才干模型:
A)Competency=Natural&Acquired Abilities(先天才能以及后天通过学习获得的才能)×Drive&Motivation(先天因为性格和智能所产生的动力以及后天通过价值观形成的动机而成的干劲),所以competency的正确翻译为才能与干劲,简称才干。
B)6C通用的人才培养框架
Care关爱–Self个人,Family家庭,Society社会,Environment环境;
Cognition认知–Learn to Learn学习怎样学习,Self-discovery自我发现,Thinking思维,Technologies科技,Humanities人文;
Culture文化–Own Culture自己的地域文化,Other Cultures他人的地域文化,Corporate Culture企业文化;
Communication沟通–Intrapersonal Communication内在反省的沟通,Interpersonal Communication人际关系的沟通,Communication Media&Tools沟通的媒介与工具;
Co-creation共创–Collaborative Creation&Innovation协作式创造创新,Problem Solving解决问题,Results/Values Orientation结果/价值导向;
Confidence自信–Self-esteem&Dignity自尊,Trustworthiness可信,Assertiveness坚定,Attitudes(Values&Beliefs)态度(价值观与信念),Resilience坚韧;
C)PILLAR专用的职场人才评估框架
6C框架下面的不同层次的元素组成了PILLAR:
Project Performance项目绩效才干–Co-creation共创;
Innovation&Influencing创新与影响才干–Collaborative Innovation协作式创新,Cognition Diversity多元认知&Communication沟通,Values价值观,Trust信任;
Learning学习才干–Cognition Diversity多元认知,Learn to Learn学习怎样学习;

Attitudes态度–Values价值观,Beliefs信念;
Resilience坚韧–Care关爱,Problem Solving解决问题,Results/ValuesOrientation结果/价值导向;
才干定义与概念剖析以及6C框架的不同层次元素提炼出来的PILLAR框架配合人工智能的自然语言处理(包括端到端RNN+LSTM的语义分析)能针对候选人回复面试的开放式问题所给与的答案有打分的统一标准,同时AI有更高的效率和不受个人经验和状态的影响而产生的效果优势。
本发明提供的一种人工智能评估人才方法,基于上述模型设计了一套深度学习算法来自主学习Talent DNA模型,使其能够对候选人进行多维度评价,再利用统计方法生成详细的报告。
本发明提供的一种人工智能评估人才方法,可以利用人工智能代替人工初次面试,能够对候选人进行多维度评价,再利用统计方法生成详细的报告,并且,AI有更高的效率和不受个人经验和状态的影响而产生的效果优势。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明,不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本发明的保护范围。
