The main goal of Natural Language Processing (NLP) is to comprehend the meaning of text semantics. 

Currently, there are two distinct approaches to NLP. In the first approach, the fundamental mathematical analysis of NLP will be covered.  Students will write Python code to access NLTK, TextBlob software packages, breaking down text into tokens.  The tokenization process will be covered using Regular Expressions, NLTK and TextBlob software.  Text tokens will be converted into vectors and vectorization process, including count vectorizer, cosine similarity computation and TF-IDF (Term Frequency Inverse Document Frequency) will be explored.  The semantics of text will be analyzed using Latent Semantic Analysis (LSA).
In the second approach, students will explore Machine/Deep Learning models for NLP.  Naïve Bayes machine learning model will be used for document classification.  Deep learning tools (Keras/TensorFlow) will be used to generate Word Embeddings like Word2Vec.  Transformers, including GPT1/2/3/4, BERT for semantic analysis of text and exploration of the ChatGPT Language model will be covered. Huggingface Transformer library will be used to explore various applications of NLP like Translation, Sentiment Analysis, etc.
NLP has become an integral part of Artificial Intelligence (AI), which is expected to drive the growth in the new economy.  Since its inception in November 2022 (ChatGPT) AI has consistently dominated the news cycle. ChatGPT has resonated globally, garnering over 1 million users in its first week. Virtually all news organizations routinely file reports about how ChatGPT is revolutionizing many real-world tasks that had been done by human workers.
This course is comprehensive, covering state-of-the-art tools and techniques of NLP.
