Semi-supervised: In semi-supervised MLC (SS-MLC) , thedatasetis comprised of two sets: fully labeled data and unlabeled data. Figure 1 Illustration of some Multi-label learning settings with different types of supervision. Weak-supervised: there are three types of weak supervision. Incomplete sup...
从深度学习的角度来举例子,我们举一个大家应该很比较熟悉的人脸关键点回归问题[3]: 我们可以看到,对于很相似的一组数据,dataset的标注出现了比较大的误差(见右图的右侧边缘)。这样的误差并不是我们模型带入的,而是数据本来就存在误差。数据集里这样的bias越大,我们的偶然不确定性就应该越大。 2.认知不确定性 认...
The main objective of this work is to create a novel framework for learning and classifying imbalanced multi-label data. This work proposes a framework of two phases. The imbalanced distribution of the multi-label dataset is addressed through the proposed Borderline MLSMOTE resampling method in ...
from tensorflow.keras import backend # calculate fbeta score for multi-label classification def fbeta(y_true, y_pred, beta=2): # clip predictions y_pred = backend.clip(y_pred, 0, 1) # calculate elements for each sample tp = backend.sum(backend.round(backend.clip(y_true * y_pred, ...
Moreover, in a typical multi-label dataset, the probability of a label being negative is very high. Consequently, treating the un-annotated labels as negative may improve the discriminative power as it enables the exploitation of the entire data [14]. However, this training mode, denoted as ...
使⽤迁移学习（TransferLearning）完成图像的多标签分类 （Multi-Label）任务 本⽂通过迁移学习将训练好的VGG16模型应⽤到图像的多标签分类问题中。该项⽬数据来⾃于，每张图⽚可同时属于多个标签。模型的准确度使⽤F score进⾏量化，如下表所⽰：标签预测为Positive(1)预测为Negative(0)真值为Positive...
our MLC come from three aspects: i) the multi-scale person features for better similarity measurement, ii) the multi-label assignment based on the whole dataset ensures that every image can be trained, and iii) the self-paced clustering removes some noisy samples for better feature learning. ...
