Natural Language Processing (NLP) Training in Metro Manila, Philippines

This training offers a practical and hands-on introduction to Natural Language Processing (NLP) using Python. Participants will learn how machines process and understand human language and how to apply various NLP techniques such as text preprocessing, vectorization, sentiment analysis, named entity recognition, and topic modeling. The course combines foundational theory with real-world projects using tools like NLTK, spaCy, and Hugging Face Transformers.
