KNIME Essentials
Data cleaning is an essential step in any data analysis and machine learning workflow. Without clean data, insights can be inaccurate, leading to poor decision-making. KNIME is a powerful tool that simplifies data preparation through a drag-and-drop interface, making it easy for non-programmers to handle complex ETL (Extract, Transform, Load) tasks.
Skilled Evaluated
This course will teach you how to use KNIME for data cleaning, preparation, and Natural Language Processing (NLP) without requiring any coding knowledge. You will also learn to work with pre-trained TensorFlow models in KNIME (which involves Python coding for advanced users). By the end of the course, you will be able to handle data inconsistencies, process NLP tasks, and optimize data workflows using only KNIME nodes.
