众筹项目推荐:面向隐式反馈的深度学习协同过滤

目前,在推荐系统研究中,用户的隐式反馈,以及极度稀疏的数据,已成为影响协同过滤推荐效果的主要问题.针对这一现象,本文提出了深度学习协同过滤算法,先利用卷积神经网络,对用户-项目矩阵的隐层特征进行学习,再结合协同过滤,对用户-项目的交互信息进行建模,并将两种特征融合预测推荐列表.以众筹平台的数据为实验对象,比较模型中各参数对推荐效果的影响,并设计与基线方法的对比实验.实验结果表明:均匀采集负反馈,并在一定卷积层数的网络中,数据稀疏度越高,效果越好;对比基线方法,本文提出的算法在公开数据集(Yahoo!Movie)上取得了最好的推荐结果.本文提出的算法有助于提高众筹平台的融资成功率,同时也丰富了推荐系统的研究体系.

基于隐枚举法的快速分级切负荷优化方法

目前稳控装置广泛采用的穷举法已经很难满足快速、精准切负荷的要求。为了高效地求解切负荷优化问题,为紧急决策争取更多时间,提出了基于隐枚举法的快速分级切负荷优化方法。该方法协调低频和低压切负荷动作轮次,建立切负荷优化模型,通过制定合适的搜索策略和剪枝策略,仅在可行解范围内进行寻优,大大提高了计算最优解的效率。切负荷算例结果表明同等条件下该方法可以节约至少50%以上的计算时间,实现了稳控装置的快速切负荷,保证了紧急情况下电网的安全稳定运行。

Developing a talent training model related to chemical process safety based on interdisciplinary education in China

While chemical industrial development in China is growing rapidly, the corresponding safety training resources remain inadequate, which may often lead to increased risk of chemical accidents. These accidents are often associated with the negligence of safety management, poor safety hazard awareness, and lack of safety practice. In order to alleviate these prominent risk factors in chemical industries in China, our study develops a talent training model related to chemical process safety. First, we propose an approach for establishing the “talent training model” related to chemical process safety, consisting of three steps: analyzing the current status and existing problems of talent training related to chemical process safety, determining the theoretical basis and training objectives for developing interdisciplinary talents, and designing a new talent training model. Second, we establish a talent training model using the proposed method, which includes a comprehensive curriculum system, a diversified teaching pattern, and a quintuple evaluation method. Furtherly, we determine the expected outcomes of the talent training model. The research results provide an innovative chemical process safety training method that is applicable nationwide, also it works as a reference for other rapidly developing countries in the chemical process industry to improve safety within the chemical industry.     

Nature,Nurture and PDP: Preposterous Developmental Postulates?

In this article I discuss the nature/nurture debate in terms of evidence and theorizing from the field of cognitive development, and pinpoint various problems where the Connectionist framework needs to be further explored from this perspective. Evidence from normal and abnormal developmental phenotypes points to some domain-specific constraints on early learning. Yet, by invoking the dynamics of epigenesis, I avoid recourse to a strong Nativist stance and remain within the general spirit of Connectionism.
