Sequence Classification with LSTM Recurrent Neural Networks in Python with Keras

Last Updated on September 3, 2020 Sequence classification is a predictive modeling problem where you have some sequence of inputs over space or time and the task is to predict a category for the sequence. What makes this problem difficult is that the sequences can vary in length, be comprised of a very large vocabulary of input symbols and may require the model to learn the long-term context or dependencies between symbols in the input sequence. In this post, you […]
