information gain ratio
英漢例句
- At the same time, compare to traditional feature selection methods : odd ratio and information gain, the normal-based method yields better classification performance.
基于法向量的特征選擇算法可以在較大幅度減少計算資源消耗的同時基本維持所得到的分類器性能。 - Fourthly, for linear SVM classifier, explore the performance of normal-based feature selection method by comparing it with two traditional feature selection methods: odd ratio and information gain.
第四，研究對于線性SVM分類器，選用基于法向量的特征選擇算法，和傳統(tǒng)的基于幾率比和基于信息增益的特征選擇算法，對文本分類性能的影響。 - Its log-likeli-ratio outputs provide soft information for the cascading parallel channel decoders to obtain the soft gain, and the decoding complexity is linear with antenna number.
它利用基于均值軟輸出估計算法的似然比輸出，為譯碼器組提供軟輸入信息，使接收機運算量與發(fā)射天線的數(shù)目呈線性關系。
