Research on Action Recognition Based on Multi-task Learning Methods [PDF]
, 2015 多任务学习是机器学习和数据挖掘研究领域的前沿课题。多任务学习的目标是通过利用多个相关任务之间的内在相关性，来提高其泛化能力。在许多现实分类问题中，多任务学习已被证明相比于传统单任务学习更有效。比如，在智能交通上，生物信息学,web搜索排名,疫苗设计等等。但在一些真实应用中，多任务中存在不相关（异常）任务。与此同时，对具有高维特征的训练样本进行多任务学习时，特征维度往往是远大于训练样本的。为了同时解决多任务学习中的异常任务问题和特征选择问题，因此本文对多任务学习展开研究。本文的主要工作和贡献有三个方面 ...

Research on Drift Elimination Algorithm for Inertial Navigation System Based on EKF [PDF]
, 2016 我国的捷联式惯性导航系统领域虽然仍处于初步发展阶段，不能满足商业化应用对产品的长时间高精度的定位要求，但该方案能够解决全球定位系统在室内和极端环境下的定位问题，因此越来越多的研究机构参与其中。捷联式惯性导航系统的误差源，主要是指器件本身的误差、系统模型误差以及工程计算环节引入的误差，此类误差虽然在短时间内不会对系统精度造成太大影响，但随着误差累计会使系统出现方向漂移。本文拟提出了一种基于扩展卡尔曼滤波器的复合型航向误差消除算法以解决上述缺陷。 本文使用基于扩展卡尔曼滤波器的惯性导航系统模型。其次 ...
