NLP-Natural Language Processing in Python(Theory & Projects)

Comprehensive Course Description:

Natural Language Processing (NLP), a subdivision of Artificial Intelligence (AI), is the ability of a computer to understand human language the way it’s spoken and written. Human language is typically referred to as natural language.

Humans also have different sensors. For instance, ears perform the function of hearing, and eyes perform the function of seeing. Similarly, computers have programs for reading and microphones for collecting audio. Just as the human brain processes an input, a computer program processes a specific input. And during processing, the program converts the input into code that the computer understands.

This course, Natural Language Processing (NLP), Theory and Practice in Python, introduces you to the concepts, tools, and techniques of machine learning for text data. You will learn the elementary concepts as well as emerging trends in the field of NLP. You will also learn about the implementation and evaluation of different NLP applications using deep learning methods.

Why Use Python for NLP?

Python is the most preferred language for NLP thanks to its expansive tools and libraries for text analysis and computer-usable data extraction. This course will take you through numerous techniques for text pre-processing, from basics such as regular expressions and text normalization to complex topics such as string matching, language models, and word embeddings.

You will be considering most of the examples from the English language for understanding the algorithms. But the algorithms can be adapted to any language. (Hence, there’s no language/grammar dependency.) You will get exposure to state-of-the-art packages (NLTK, Gensim, SpaCy) as well as frameworks (PyTorch) along with extensive implementation/coding-oriented content in Python. The main focus of the course is on preparing text data for machine learning models.

Although we have separate courses on Deep learning, we do cover useful concepts in this course briefly to make this course more independent.

How Is This NLP Course Different?

The course content is very specific and to the point. The learning material is a perfect blend of theoretical concepts and practical applications. Examples and sample code have been included to help you grasp each concept with more clarity. Each NLP concept is structured and presented in such a way that makes it easy for you to understand.

High-quality video content, compelling course material, assessment questions, course notes, and handouts are additional perks that you will get. You can contact our friendly team in case of any queries.

This course encourages you to make quick progress. At the end of each module, you will get an opportunity to revise everything you have learned through Homework/tasks/activities. They have been designed to evaluate / further build your learning based on the concepts and methods you have learned. Most of these assignments are coding-based, and they will be useful to get you up and go ahead with implementations.

The two mini-projects in the last module—Neural Machine/Language Translator and Modify Language Translator a Bit and Build a Chatbot—focus on the innovative applications in this field. These mini-projects help you to apply the concepts of pre-processing text. You will use techniques such as parts of speech tagging, lemmatization, and tokenization using Python libraries.

NLP has made tremendous advances in the last decade, and it’s made the leap from research labs to real-world applications. While getting started in this field can be a challenging pursuit, this course presents you with a clear and actionable roadmap. It makes the task of accomplishing your career goals that much easier.

This course is competitively priced and delivers value for money, as you can learn the concepts and methodologies of NLP at a relatively low cost. The series of brief videos and the detailed code notebooks shorten your learning curve.
