We use Keras' to_categorical() function to one-hot encode the labels, this is a binary classification, so it'll convert the label 0 to [1, 0] vector and 1 to [0, 1]. But in general, it converts categorical labels to a fixed-length vector. After that, we split our dataset into...

How to Use Keras Models to Make Predictions After a model is defined with either the Sequential or Functional API, various functions need to be created in preparation for training and fitting a model, before we can use it to make a prediction: In this example, a Keras Sequential model is ...
In this quick tutorial, I am going to show you two simple examples to use the sparse_categorical_crossentropy loss function and the sparse_categorical_accuracy metric when compiling your Keras model.Example one - MNIST classificationAs one of the multi-class, single-label classification datasets, ...

Can you use a function to calculate the difference between two lists in Python? What is the best way to calculate the difference between two sets in Python? 在Python中计算差异值有多种方法,以下是其中一种常见的方法: 方法一:使用减法运算符 可以使用减法运算符来计算差异值。假设有两个变量a...
After the training, we will provide the input and write a plot function to see the final results. pred = model.predict(x_test_noisy) plt.figure(figsize=(20, 4)) for i in range(5): # Display original ax = plt.subplot(2, 5, i + 1) plt.imshow(x_test_noisy[i].reshape(28, 28...
