Datasets - Keras Documentation - faroit keras.datasets.reuters. Dataset of 11,228 newswires from Reuters, labeled over 46 topics. As with the IMDB dataset, each wire is encoded as a sequence of word indexes (same conventions). Usage: (X_train, y_train), (X_test, y_test) = reuters.load_data(path="reuters.pkl", \ nb_words=None, skip_top=0, maxlen=None, test_split=0.1, seed=113) Tutorial On Keras Tokenizer For Text Classification in NLP To do this we will make use of the Reuters data set that can be directly imported from the Keras library or can be downloaded from Kaggle. This data set contains 11,228 newswires from Reuters having 46 topics as labels. We will make use of different modes present in Keras tokenizer and will build deep neural networks for classification. The Reuters Dataset · Martin Thoma The Reuters Dataset Reuters is a benchmark dataset for document classification . To be more precise, it is a multi-class (e.g. there are multiple classes), multi-label (e.g. each document can belong to many classes) dataset. It has 90 classes, 7769 training documents and 3019 testing documents . TensorFlow - tf.keras.datasets.mnist.load_data - Loads the MNIST dataset. This is a dataset of 60,000 28x28 grayscale images of the 10 digits, along with a test set of 10,000 images. More info can be found at the MNIST homepage. Args path path where to cache the dataset locally (relative to ~/.keras/datasets). Returns Tuple of NumPy arrays: (x_train, y_train), (x_test, y_test).

Multiclass Classification and Information Bottleneck - Medium The Labels for this problem include 46 different classes. The labels are represented as integers in the range 1 to 46. To vectorize the labels, we could either, Cast the labels as integer tensors One-Hot encode the label data We will go ahead with One-Hot Encoding of the label data. This will give us tensors, whose second axis has 46 dimensions. Datasets - keras-contrib Dataset of 50,000 32x32 color training images, labeled over 100 categories, and 10,000 test images.
