🤟🏼Natural Language Processing

What do you learn in Natural Language Processing

Natural Language Processing (NLP) covers how computers understand and generate human language. You'll learn about text preprocessing, tokenization, part-of-speech tagging, and parsing. The course dives into machine learning models for language tasks, sentiment analysis, and information extraction. You'll also explore neural networks for language processing and work on building chatbots or language translation systems.

Is Natural Language Processing hard?

NLP can be challenging, especially if you're new to machine learning or linguistics. The math behind some algorithms can be tricky, and there's a lot of new terminology to grasp. But don't worry, it's not impossible. With consistent effort and practice, most students find it manageable. The cool applications and projects make the difficulty worth it.
