keras预报_类(文档)输出一个类别预测的numpy数组.在您的模型案例中,哪一个是来自您的最后一层(softmax)的最高激活神经元的索引. [[0]]
意味着您的模型预测您的测试数据为0类.(通常,您将传递多个图像,结果看起来像[[0], [1], [1], [0]]
)
keras predict_classes (docs) outputs A numpy array of class predictions. Which in your model case, the index of neuron of highest activation from your last(softmax) layer. [[0]]
means that your model predicted that your test data is class 0. (usually you will be passing multiple image, and the result will look like [[0], [1], [1], [0]]
)
您必须将实际标签(例如'cancer', 'not cancer'
)转换为二进制编码(对于癌症,0
,对于非癌症",1
)进行二进制分类.然后,您将[[0]]
的序列输出解释为具有类标签'cancer'
You must convert your actual label (e.g. 'cancer', 'not cancer'
) into binary encoding (0
for 'cancer', 1
for 'not cancer') for binary classification. Then you will interpret your sequence output of [[0]]
as having class label 'cancer'
