KNIME for Machine Learning: Building Predictive Models

Using the KNIME Analytics Platform, you can create complex analyses easily thanks to its visual user interface. Can the information science lifecycle be fully robotized? Can a machine learning model be automatically generated from a set of data? Data science tools have appeared in recent months claiming to automate parts or all of the process. How much work would be required to adapt one of these devices to your own concerns and information arrangement?

KNIME investigation stage

In addition to Information Preparing, KNIME Investigation Stage includes AI, Information Representation and much more. The key benefits are as follows:

  • No programming knowledge is needed to create a machine learning model.
  • The user-defined logic statements and rules allow you to match desired rows.
  • All machine learning algorithms are supported, and the user interface is user-friendly.

Data partitioning 

Partitioning our dataset will allow us to divide it into training and testing sets for our model. To divide the dataset, we use the Partitioning node. Using defined examining, we ensure that values in the segment “Administered” are (roughly) distributed across both the train and test datasets. Once everything is connected, here is how it looks.

Train, test, assess: Machine Learning Process

As of now, we simply need to feed our information into an AI calculation. Machine learning algorithms will be used in two different ways. Our models will be prepared and tested in this way. The performance of these two models can also be compared simultaneously. Connect the nodes by dragging and dropping the desired note onto the Workflow Editor after finding the name of the machine learning algorithm in the Node Repository.

How does Knime stand out from the competition?

Knime Analytics was named a leader in the Gartner Magic Quadrant in March of this year for the fifth consecutive time, according to Forest Grove Technology. Among the remaining leaders for this year are Alteryx, SAS, RapidMinder, and H2Oai. 

In Knime (pronounced “kime”), blocks representing data science workflow steps are connected using a graphical user interface. A wide range of built-in functions are available, including data access and transformation, statistical inference algorithms, machine learning algorithms, PMML, custom nodes for Python, Java, R, Scala, and a zillion other languages, as well as community plugins (since it is open source, anyone can make plugins). Knime also enforces structure and modularity on data science workflows, requiring code to fit into specific building blocks.


Usually, robotized AI has a high cost due to a lack of control. Automated systems sacrifice fine-tuning or interpretability for efficiency. Although such a cost might be manageable for well-defined domains, it might become prohibitive for domains with greater complexity. It is alluring to have a specific connection with the client in such cases.
