For example, we raise the number of neurons from 100 to 300 and change the number https://www.metadialog.com/blog/sentiment-analysis-and-nlp/ of hidden layers from one to three. Mittal et al.  proposed deep graph-LSTM for text classification. The study produced an accuracy of 99% when classifying the related category of a fresh case. Access to comprehensive customer support to help you get the most out of the tool.
