keras predict_classes (docs) 输出类预测的 numpy 数组.在您的模型案例中,您的最后一个(softmax)层的最高激活神经元的索引.[[0]]
意味着你的模型预测你的测试数据是 0 类.(通常你会传递多张图像,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'、'notcancer'
)转换为二进制编码(0
代表 'cancer'、1
代码> 表示非癌症")进行二元分类.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'
