Change the loss function to loss = 'sparse_categorical_crossentropy'. This will work, and you don't have to change the input data shape.

Jun 20, 2020 · Or does Keras automatically convert the categorical output to numeric? EDIT: To be extra clear, I know how to one-hot encode it, but my question is why they didn't do that. In the example, the net worked without one-hot encoding the target classes, while the net's output was clearly one-hot encoded. EDIT: Roshin was right.

What Is One-Hot encoding?

The tf.keras.datasets module provide a few toy datasets (already-vectorized, in Numpy format) that can be used for debugging a model or creating simple code examples. If you are looking for larger & more useful ready-to-use datasets, take a look at TensorFlow Datasets. Available datasets MNIST digits classification dataset load_data function

First, tf.one_hot is simply an operation, so we'll need to create a Neural Network layer that uses this operation in order to include the One ...

mnist = input_data.read_data_sets ("MNIST_data/", one_hot=True) So what this does is it says download the data, save it to the MNIST_data folder, and process it so that data is in one hot encoded format. One hot encoded format means that our data consists of a vector like this with nine entries. [1 0 0 0 0 0]

07.04.2021 · 2-layer NN with tf.keras to solve MNIST (part 1) Digit classification using MNIST dataset is kind of “hello world” exercise to Neural Net and Deep Learning (DL) – i.e. an introductory example to demonstrate neural networks. Although I plant to blog a more interesting DL modeling in the future, I still think it is always nice to have a ...

19.06.2020 · When I load the mnist dataset from Keras, I get 4 variables - (x_train, y_train), (x_test, y_test) = keras.datasets.mnist.load_data() The shape of x_train is (60000, 28, 28), which makes sense because it contains 60,000 28x28 pictures. The shape of the y_train is just (60000,) which shows that it is a one-dimensional vector which contains numeric target labels (0-9).
