More specifically, it quantifies the "amount of information" (in units such as shannons , nats or hartleys) obtained about one random variable by observing the other random variable. ⁡. The data is stored in X and a co-clustering model using direct maximisation of the modularity is then fitted with 4 clusters. Share Add to my Kit . This would be described by a 2 dimensional matrix as in https://stackoverflow.com/questions/20491028/optimal-way-to-compute-pairwise-mutual-information-using-numpy. In our experiments, we have found that a standard deviation of 0.4 works well for images normalized to have a mean of zero and standard deviation of 1.0. It gives their de nitions in terms of prob- abilities, and a few simple examples. mutual information Parameters im1, im2 ndarray. Mutual information of words is often used as a significance function for the computation of collocations in corpus linguistics. mutual information python kandi X-RAY | NMI REVIEW AND RATINGS. The Mutual Information is a measure of the similarity between two labels of the same data. 导航. 4). python Mutual Information Any dimensionality with same shape. These examples are extracted from open source projects. By voting up you can indicate which examples are most useful and appropriate. In this function, mutual information is normalized by some generalized mean of H (labels_true) and H (labels_pred)), defined by the average_method. normalized Images. sklearn.metrics.normalized_mutual_info_score — scikit-learn 0.17 python 专栏收录该内容 18 篇文章 2 订阅 订阅专栏 标准化互信息（normalized Mutual Information, NMI）用于度量聚类结果的相似程度，是community detection的重要指标之一，其取值范围在 [0 1]之间，值越大表示聚类结果越相近，且对于 [1, 1, 1, 2] 和 [2, 2, 2, 1]的结果判断为相同 其论文可参见 Effect of size heterogeneity on community identification in complex …
