职业教育类型化视域下,以资历框架中的能力标准作为人才培养目标确定和实施教育效果评价的参考依据,能够使得职业教育在不断对标国家质量标准的过程中进一步强化类型定位。资历框架内蕴强化统一标准、建构内在互动、强调主体自觉和实施成效为本的核心隐喻,其不仅能够打通职业教育学习者的成长通道,也能为职业教育专业群建设、课程开发、教师队伍构建等提供标准体系,为职业教育的类型化发展奠定了基础。具体来说,职业教育类型化视域下的资历框架建设目标为以资历框架支撑内容标准架构、以资历框架整合多元行动主体、以资历框架聚集优质教育资源、以资历框架支持学习个性化和以资历框架培养终身学习习惯,主要内容为强化标准建设、规则建设和应用模式建设。参考国外多个国家和国内有关资历框架建设经验,职业教育资历框架体系应该具备高层级性、等值融通性、动态适应性和终身性等典型特征,使得职业教育资历框架能够深刻对接现代产业结构高级化发展对高技能人才的现实需求,进一步彰显职业教育的类型属性。

探讨人口流失地区的就地城镇化特征与影响因素,对于推动形成“以县城为重要载体的就地城镇化模式”具有重要参考意义。文章以四川省72个县域单元为研究范围,以典型个例——岳池县的留守农民调查数据为支撑,运用多元逻辑回归分析,从个人、家庭、生产生活、养老和教育4个层次分析留守农民的不同居住地域迁移意愿和影响因素。研究发现:一、与其他地区不同,人口流失地区城镇化在空间-经济-人口3个层面分异明显,近40%的留守农民有城镇化倾向,迁移意愿和偏好强度依次为县城>大城市>地级市>小城镇;二、就地城镇化影响因素呈现“轻生产、重生活”特征,即不以收入、就业为首要导向,而是将家庭养老和子女教育视为就地城镇化的决定性因素。最后,基于此提出构建完善的城乡教育与养老服务体系,并积极探索内生型城镇化发展路径的政策建议。

Efficient and effective Bayesian network local structure learning

引用

Frontiers of Computer Science 2014年第4期8卷 527-536页

作者： Jianjun YANG Yunhai TONG Zitian WANG shaohua tan Center for Information Science Peking University Beijing 100871 China Agricultural Bank of China Beijing 100871 China

In this paper, we propose a more efficient Bayesian network structure learning algorithm under the framework of score based local learning （SLL）. Our algorithm significantly improves computational efficiency by restricting the neighbors of each variable to a small subset of candidates and storing necessary information to uncover the spouses, at the same time guaranteeing to find the optimal neighbor set in the same sense as SLL. The algorithm is the- oretically sound in the sense that it is optimal in the limit of large sample size. Empirical results testify its improved speed without loss of quality in the learned structures.

Improved IAMB with Expanded Markov Blanket for High-Dimensional Time Series Prediction

引用

Chinese Journal of Electronics 2016年第2期25卷 264-269页

作者： YANG Xianglin TONG Yunhai YANG Jianjun YAN Hong WANG Hongbo tan shaohua Key Laboratory of Machine Perception (Ministry of Education) School of Electronics Engineering and Computer SciencePeking University State Key Laboratory of Space Medicine Fundamentals and Application China Astronaut Research and Training Center

The classic regression model for multivariate time series prediction suffers from the curse of dimensionality because the least squares estimates become unreliable when the predictors of the time series are large and the number of samples is limited. The classic methods such as ridge regression, lasso regression, principal component regression are researched to solve the problem above. The ridge regression and principal component regression can not give the clear interpretation features for prediction,and lasso regression does not work well under collinearity, also the selections given by lasso regression are unstable and very sensitive to minor perturbations of the data.A practical method based on improved Incremental association Markov blanket(IAMB) with Expanded Markov blanket(EMB) was proposed for high-dimensional time series prediction. The EMB was constructed with simultaneous predictors and past predictors for time series. Since the faithfulness condition and reliable conditional independence test are not satisfied for high-dimensional time series with limited samples in practical applications. The symmetry of Markov blanket(MB) and the partial correlation coefficient criterion for conditional independent test were employed to learn the EMB, on which the regression was used for prediction. Empirical results show that our method based on EMB for macroeconomic prediction has less mean-square forecast error than other classic methods,especially when predicting the value with sharp fluctuation.
