ValueError: multilabel-indicator is not supported 这个错误信息通常出现在使用机器学习库(如 scikit-learn)进行多标签分类任务时。它表明你尝试使用的模型或函数不支持以“multilabel-indicator”格式输入的多标签数据。 2. 常见原因 模型不支持:你使用的模型或函数本身不支持多标签分类任务,或者不支持以特定格式(如 ...
In multilabel learning, the joint set of binary classification tasks is expressed with label binary indicator array: each sample is one row of a 2d array of shape (n_samples, n_classes) with binary values: the one, i.e. the non zero elements, corresponds to the subset of labels. An a...

Multi-label learning with missing labels is a challenging task, especially in text classification applications. Existing approaches considering label corre
I is the indicator function that takes the value 1 if yijtytij is not equal to yijyij and 0 otherwise. The following formula is used to determine the voting weights of the current classifier at different labels: 27 αjt=12ln1−errjterrjt,j=1,…,q,t=1,…,T.αtj=12ln1−errtje...
wheremis the number of samples.I(\bullet )is the indicator function, it is equal to 1 when{y}^{\left(i\right)}is same as{\widehat{y}}^{(i)}, otherwise it is equal to 0. As observed, a higher MR value indicates a higher accuracy in classification. ...

Given a PML training set D={(xi,yi)}i=1n, where xi∈Rd denotes the d-dimensional input feature vector for the ith instance, yi∈{0,1}L is the corresponding assigned label indicator vector for the ith instance. The labels assigned with 1 in yi form the candidate label set Si, which...
