Executive Development Programme in Text Classification and Topic Modeling in Python

This course is designed for professionals and data scientists seeking to enhance their skills in text classification and topic modeling using Python. Participants will gain expertise in applying machine learning techniques to analyze and categorize textual data, enabling them to derive meaningful insights from unstructured text.

Participants will learn to implement state-of-the-art algorithms, work with natural language processing libraries like NLTK and spaCy, and use popular Python frameworks such as scikit-learn and Gensim. By the end, they will be able to build and evaluate text classification models and perform topic modeling to uncover hidden themes in large datasets.
