Natural Language Processing (NLP) is one of the most exciting fields in Machine Learning and AI. In this beginner-friendly workshop, I will introduce Keras as a Python library for applying NLP techniques on a multi-label emotion classification dataset and present how to use it to build a deep learning classifier. Besides, I will also compare and demonstrate how applying NLP techniques improve the predictability of a model and then, tune a neural network using Keras Tuner to boost the overall model performance.
