Text classification



In this post we will implement a model similar to cnn-text-classification-tf - Convolutional Neural Network for Text Classification in Tensorflow. Such more general classes are usually referred to as topics , and the classification task is then called text classification , text categorization , topic classification , or topic spotting .
