查询词典 learning

In this paper, we discuss the learning control for nonlinear discrete system with delay. It is not necessary to use the desired input corresponding to the desired output and the desired state corresponding to the system in our learning algorithm and in the process of learning control. Therefore, our method needs less dynamics information of the controlled object than previous ones and only the qualitative Lipschitz condition is required.

摘 要：讨论了滞后非线性离散系统的学习控制问题，由于所给的学习算法及学习控制过程中，没有涉及和用到相应于理想输出yd的理想输入ud及对应于系统的理想状态xd，故对被控对象的动力学信息要求得很少，只是一种定性上的Lipschitz条件。

The thesis is based mostly on three recent papers on learning gibbs distributions. They are [Zhu 97]"s work on creating a unified statistical framework by minimax entropy principle, which is then used to learn texture images, [Guo 01]"s proposal for learning the distribution of intrinsic texture element by gibbs model and [Liu 01]s introduction of the minimax Entropy idea to the learning of Inhomogeneous Gibbs Model.

本论文的基本出发点是基于下面三篇关于吉布斯学习的重要文献，即[Zhu 97]中创造的用最小最大熵准则学习纹理图像分布的一套统计框架，[Guo 01]中提到的用吉布斯模型学习纹理基元分布的方法，以及[Liu 01]中介绍的关于非均匀吉布斯模型(Inhomogeneous Gibbs Model，简称IGM)的学习机制。

The results indicate that female wasps deposit HMPs on the chorion of host eggs with her ovipositor near the end of egg-laying process. Na ye females do not posses the ability for recognizing the marking pheromones and have to obtain the ability though the learning process, in which the wasp inserts her ovipositor into a host egg to determine whether the egg has been parasitized followed by antennal drumming on the exterior. Once the learning process is completed, the female wasp will be able to discriminate between parasitized and unparasitized hosts and reject a parasitized egg by simply drumming on the exterior of the egg. Learning plays an important role in reducing initial rejection time when an unsuitable host is encountered. Female wasps of T. astriniae can quickly learn to associate the presence of a HMP on host egg chrion with the internal status of the egg.

研究结果表明，玉米螟赤眼蜂的寄主标记信息素是在其产卵过程中的收场阶段由产卵器产生的，并且标记在寄主卵表的化学物质；玉米螟赤眼蜂对标记信息素的识别不具有先天性，其必须先用产卵器插入寄生卵来检测是否被寄生，然后其触角不停地敲击，通过学习获得对标记信息素的识别能力，从而放弃了对寄生卵的选择，学习对初始放弃时间有着重要影响，改善了其对寄主搜索效率，这种学习行为是与寄主联系在一起学习的，它能根据寄主被寄生与否而对标记信息素作出反应与不反应。
