Python NLP: Machine Learning Models for Text Processing

Text data is everywhere, but turning raw words into actionable insights requires specialized machine learning techniques. This text-based course guides you through the foundational concepts of Natural Language Processing (NLP) and teaches you how to build predictive models using Python. You will transition from understanding basic text structure to implementing machine learning algorithms that can classify sentiment, group documents, and extract meaning from unstructured text. What you'll learn: Understand foundational NLP concepts, including tokenization, stemming, lemmatization, and stop-word removal; Convert text into numerical features using techniques like TF-IDF and modern vector embeddings; Build and train machine learning models for sentiment analysis and text classification; Apply clean Python coding practices, including type hints, to organize your machine learning pipeline; Explore the basics of modern transformer models and how they differ from traditional machine learning approaches; Evaluate model performance using metrics like precision, recall, and F1-score. The course begins with core terminology and essential text-preprocessing techniques. You will then progress through feature engineering, model training, and performance evaluation, using written explanations and practical Python code snippets. This course is designed for beginners in data science and Python programmers who want to enter the field of Natural Language Processing. No prior NLP experience is required.
