    • A system and method for evolving appropriate connections in feedforward topological networks (Fig. 1) illustrates an exemplary flow diagram of a method for evolving appropriate connections in a neural network device according to an aspect of the present invention. Initially, weight changes induced by each particular training sample or pattern are calculated using, for example, a conventional network training rule such as Hebb or backpropagation (step 101). Next, a ratio of the weight changes for existing connections to incipient connections ("K" ratio) is calculated (step 103). If this K ratio exceeds a specified threshold, weight changes are implemented (step 105), in which existing weights are increased by (1-E)x(total weight change of existing connections), where E is a network-wide parameter. The remaining amount (E)x(total weight change of existing connections) is added to form neighboring connections (step 107). It is to be noted that if neighboring connections are not yet in existence (i.e, they are incipient connections), they can be created by this mutation rule; however, whether such new connections are created depends on the size of the weight increase computed in step 101, together with the magnitude of E. After cycling through a training set, connections that are weak (e.g., weaker than a specified threshold) are deleted (step 109). Following step 109, the system returns to step 101. Advantageously, a system and method according to the present invention allows a combination of the advantages of fully connected networks and of sparse networks and reduces the number of calculations that must be done, since only the calculations corresponding to the existing connections and their neighbors need be determined.
    • 用于在前馈拓扑网络中演进适当连接的系统和方法(图1)示出了根据本发明的一个方面的用于演进神经网络设备中的适当连接的方法的示例性流程图。 首先,使用例如常规网络训练规则(例如Hebb或反向传播)来计算由每个特定训练样本或模式引起的体重变化(步骤101)。 接下来,计算现有连接的重量变化与初始连接的比率(“K”比)(步骤103)。 如果该K比率超过规定的阈值,则实施权重改变(步骤105),其中现有权重通过(1-E)×(现有连接的总权重变化)增加,其中E是网络范围的参数。 添加剩余量(E)x(现有连接的总重量变化)以形成相邻连接(步骤107)。 要注意的是,如果邻居连接尚未存在(即它们是初始连接),则可以通过该突变规则来创建它们; 然而,是否创建这样的新连接是否取决于在步骤101中计算的权重增加的大小以及E的大小。在循环通过训练集之后,删除弱(例如,弱于指定阈值)的连接 (步骤109)。 在步骤109之后,系统返回到步骤101.有利地,根据本发明的系统和方法允许将完全连接的网络和稀疏网络的优点组合,并且减少必须进行的计算的数量,因为只有 需要确定对应于现有连接及其邻居的计算。

    • Two computer workstations are connected together by a communications link (300). One workstation (the local workstation) (100) includes a window (610) which is used to display a copy of what is currently being displayed on the screen of the other (remote) workstation (200). Each time an update is made to the screen of the remote workstation, it must be transmitted to the local workstation. A bounding rectangle (920) for the area of the screen changed by the update is determined. If the bounding rectangle is greater than a predetermined size, then a first packet is transmitted from the remote workstation to the local workstation, prior to the transmission of the actual update itself. This first packet indicates the bounding rectangle for the updated area of screen. The local workstation responds to the first packet by greying (shading) the corresponding region (925) of the window which contains the copy of the remote screen, thereby indicating to a user of the local screen that an update is imminent.
    • 两个计算机工作站通过通信链路连接在一起(300)。 一个工作站(本地工作站)(100)包括窗口(610),用于显示当前正在其他(远程)工作站(200)的屏幕上显示的内容的副本。 每次对远程工作站的屏幕进行更新时,必须将其传输到本地工作站。 确定由更新改变的屏幕区域的边界矩形(920)。 如果边界矩形大于预定大小,则在实际更新本身的发送之前,将第一分组从远程工作站发送到本地工作站。 该第一个分组指示更新的屏幕区域的边界矩形。 本地工作站通过使包含远程屏幕的副本的窗口的对应区域(925)灰化(阴影)来响应第一分组,从而向用户向本地屏幕指示更新即将到来。
