Overview

“Text Mining with Classical Methods” is a compact live course in the field of Data Science and Classical Machine Learning. It centres on Tokenization and stop words, TF-IDF and Bag of words – explained with realistic examples and deepened in exercises you can transfer straight to your daily work.

Data science creates value when data is prepared cleanly, models are chosen sensibly and results are communicated transparently. Our courses cover the whole path: from data preparation and exploratory analysis through classical methods such as classification, regression and clustering to model evaluation and MLOps basics. Text Mining with Classical Methods is a one-day workshop with compact input and exercises on realistic datasets. You work with Python, SQL and established platforms and take home notebooks, templates and checklists for your own projects.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.
