Developing Machine Learning models is always considered very challenging due to its cryptic nature.
Generally, to develop machine learning applications, you must be a good developer with expertise in command-driven development.
The introduction of KNIME has brought the development of Machine Learning models in the purview of a common man.
KNIME provides a graphical interface (a user-friendly GUI) for the entire development. In KNIME, you simply have to define the workflow between the various predefined nodes provided in its repository.
