适用场景:一个输入对应多个label,或输入类别间不互斥 调用函数: 1. Pytorch使用torch.nn.BCEloss 2. Tensorflow使用tf.losses.sigmoid_cross_entropy 3. Caffe使用SigmoidCrossEntropyLoss 在output和target之间构建binary cross entropy,其中i为每一个类。 以pytorch为例:Caffe,TensorFlow版本类比,输入均为相同形式的向...

Multi-Label Image Classification Multi-label image classification is a task where a computer is trained to recognize and assign multiple labels or tags to an image.Instead of assigning a single category to an image, as in the case of multi-class classification, multi-label classification allows ...
For each image (row entry in CSV), there must be one and only one label for each task cell. An example for train.csv with 3 classification tasks (color, type and size) is like following: fname color type size 1.jpg Blue 1 Big 2.jpg Red 1 Small 3.jpg Red 0 Small Note: ...
Image byFreepik In machine learning tasks, classification is a supervised learning method to predict the label given the input data. For example, we want to predict if someone is interested in the sales offering using their historical features. By training the machine learning model using available...
