The algorithm ID3 (Quinlan) uses the method top-down induction of decision trees. Given a set of classified examples a decision tree is induced, biased by the information gain measure, which heuristically leads to small trees. The examples are given in attribute-value representation. The set of possible classes is finite. Only tests, that split the set of instances of the underlying example languages depending on the value of a single attribute are supported.

在图形中若于个边(edge)上加上一些值,此数值称为比重( weight ) 。而此图形称为比重图形(Weight Graph ) ,若weight是成本( cost )或距离( distance ) ,则称此图形为网路( Network )。根据Spanning Tree的定义,知一个图形可有许多不同spanning tree ,在network中找出一个具有最小成本( Cost )的Spanning tree ,则此Spanning tree称为最小成本生成树。

The object detector described below has been initially proposed by P.F. Felzenszwalb in [Felzenszwalb2010]. It is based on a Dalal-Triggs detector that uses a single filter on histogram of oriented gradients (HOG) features to represent an object category. This detector uses a sliding window approach, where a filter is applied at all positions and scales of an image. The first innovation is enriching the Dalal-Triggs model using a star-structured part-based model defined by a “root” filter (analogous to the Dalal-Triggs filter) plus a set of parts filters and associated deformation models. The score of one of star models at a particular position and scale within an image is the score of the root filter at the given location plus the sum over parts of the maximum, over placements of that part, of the part filter score on its location minus a deformation cost easuring the deviation of the part from its ideal location relative to the root. Both root and part filter scores are defined by the dot product between a filter (a set of weights) and a subwindow of a feature pyramid computed from the input image. Another improvement is a representation of the class of models by a mixture of star models. The score of a mixture model at a particular position and scale is the maximum over components, of the score of that component model at the given location.

利用aiNet执行资源聚类的算法分为两部分:第一部分是aiNet学习算法,如上所述;第二部分是在获得记忆细胞矩阵M和Ab-Ab之间的dij矩阵S基础上,实现连通图的剪枝聚类。 定义 1 无向连通图G:在形态空间Sw上,以M中抗体对应的点为G的顶点,每对抗体之间的亲和力dij为G中两点连接边的权值。 定义2 最小生成树:包含连通图G中所有顶点的一个子图称为G的一棵生成树T。生成树中所用边的权值为生成树的权。权最小的生成树定义为最小生成树(Minimum spanning tree,MST)。

VIP+ is support software for YAMAHA RCX series robot controllers. In addition to the functions of the previously released "VIP Windows" software, VIP+ includes an easy-to-use GUI (graphical user interface). VIP+ also allows control by 2 or more controllers or access to a controller from 2 or more clients via Ethernet connection. ● With VIP+ you can: • Do offline editing of all data used on robot controllers • Operate and monitor robots connected to robot controllers • Do online editing of all data used with robot controllers • Back up and restore robot controller data ● Functions and features newly added to VIP+: • Ethernet connection to controllers • Supports data input in spreadsheet software format • Seamless backup and restoring of controller information such as point data • Syntax coloring • Data transfer between the online controller and an offline document by drag & drop • Executes online commands using a terminal window • Controller tree and document tree functions similar to Windows Explorer
