  • Abstract:深度学习技术往往需要大量的标记训练样本,然而真实环境中获得大量标记样本的代价昂贵,甚至难以获得.提出一种新的深度主动识别框架,借鉴人类逐步学习并获取新知识的认知过程,在基于少量样本分析模型认知错误的基础上首先定义认知错误转化,得到相应的知识来主动增强模型的认知信息.基于认知知识,选取敏感样本对模型进行在线微调,同时为了避免遗忘先前学习的知识选取先前的训练样本作为刷新样本.在通用数据集上的实验表明,敏感样本有利于提高目标识别能力,提出的认知学习机制能有效提高深度模型的性能;认知信息的特征化能有效抑制其他样本对模型认知的干扰,在线训练方法能明显节省大量训练时间.提供了一个有效的认知学习在少量数据样本情境中的应用.
