查询词典 speed

On the basis of variation characteristics of ship speed error model, a ship speed regulator using the on-line adaptive error model is proposed in this paper. The control scheme is based on back propagation multi-layer perceptrons adaptive neural network in which a modified hyperbolic tangent function is used as the activation function of an auto-tuning neuron and is updated by the steepest descent method.

In the paper,a fast image retrieval method based on the DCT domain and correlative feedback is presented,which aims at JPEG images and uses color layout descriptors in the MPEG7 standard. As the method only needs entropy decoding,the speed of extracting image features is improved and storage space saved. The experiment result shows that the method has a high retrieval speed and a good effect.

文章针对JPEG压缩图像，结合MPEG 7中建议的颜色布局描述符，提出一种带相关反馈的基于DCT域的快速图像检索方法；该方法只需要熵解码，可提高图像特征提取的速度、节省存储空间；实验结果表明，此方法具有检索效率高、检索效果好的特点。

ID〓 is characterized by the fast speed of training and classifying, and it can be applied to large-scaled learning problems. But the selection criterion of attribute is the core of ID〓, and is now doubted. AQ〓 is a type of decision rule induction, presented by Michalski, a scientist of U. S.. It is characterized by high-precision classifying and capability of knowledge expression, and it can be applied to automatic knowledge acquisition in expert system. However, the inducing and matching speed of AQ〓 is slow.
