cross entropy meaning in Chinese
交叉熵
Examples
- Motion region detection based on cross entropy in image sequences
图像序列中基于交叉熵的运动区域检测 - We do a lot of experiments on the representative fusion schemes , and use entropy , cross entropy , mutual information to evaluate the performance of them
选取其中有代表性的算法进行了大量实验，并用熵、交叉熵、交互信息量等多种评价方法进行了定量分析与比较。 - The results show that when evaluated with the indexes of cross entropy and contrast , it performs better than the wavelet transform based fusion method with the fusion rules of maximum absolute coefficient and maximum directive contrast
仿真实验表明，较之于基于最大绝对系数和最大方向对比度的小波变换融合方法而言，该方法在交叉熵和对比度意义上性能更佳。 - Based on the minimum cross entropy theory , a new model , which can forecast mortality distribution by minimizing the cross entropy function subject to the future life expectancy of insurants , is proposed
基于最小叉熵原理，建立了预测被保人死亡率分布的一个模型最小叉熵模型，该模型以叉熵函数作为目标函数，以被保人的预期寿命作为约束条件，通过最小化叉熵预测被保人的死亡率。 - On single color , it provides image2 - d minimum cross entropy based on genetic algorithm . on multi - color , it provides distill color - feature and morphologic segmentation technique . these segmentations all get good effect to make preparation for the following recognition . thirdly , this paper gives feature extraction means
另外,还研究了对背景固定的灰度视频流及彩色视频流的运动目标进行了检测分割,这些分割方法均取得了不错的效果,为目标识别作好了准备。
