It's always simple if a prepared dataset is handed to you like in the above example. Above, you simply use the reuters class of keras.datasets and use the load_data method to get the data and directly assign it to variables to hold the train and test data plus labels. 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.

Datasets - keras-contrib IMDB Movie reviews sentiment classification. Dataset of 25,000 movies reviews from IMDB, labeled by sentiment (positive/negative). Reviews have been preprocessed, and each review is encoded as a sequence of word indexes (integers). For convenience, words are indexed by overall frequency in the dataset, so that for instance the integer "3" encodes the 3rd most frequent word in the data. NLP: Text Classification using Keras - World-class cloud ... Reuters news datasets; It is composed of 11,228 newswires from Reuters which is classified into 46 different categories such as politics, sports, economics, etc. We have to import these datasets from Keras. After importing, its feature dataset and label dataset are individually stored in two tuples. The Reuters Dataset · Martin Thoma Jul 27, 2017 · 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. It is the ModApte (R(90)) subest of the Reuters-21578 benchmark . Keras Datasets | What is keras datasets? | classification ... Reuters classification dataset for newswire is somewhat like IMDB sentiment dataset irrespective of the fact Reuters dataset interacts with the newswire. It can consider dataset up to 11,228 newswires from Reuters with labels up to 46 topics. It also works in parsing and processing format. # Fashion MNIST dataset (alternative to MNIST)

python - Is there a dictionary for labels in keras.reuters ... I managed to get an AI running that predicts the classes of the reuters newswire dataset. However, I am desperately looking for a way to convert my predictions (intgers) to topics. There has to be a dictionary -like the reuters.get_word_index for the training data- that has 46 entries and links each integer to its topic (string). Thanks for ...
