Weka is a machine algorithm learning application that can help data analysts solve different issues using data mining concepts.
You can use it directly on the real-time data set or even use it on the Java code. Weka provides you access to multiple tools. These tools include pre-data processing tools, regression, visualization rules, association rules, etc. All these tools and the easy access for the application make Weka worth having for the data scientists. You can also develop new schemes for machine learning using this application.
However, one of the problems with this tool is that it does not handle the multi-relational mining or sequential mining. It can only process a single data file at a particular point in time. Additionally, you should have the basic mining knowledge to use this tool. As a beginner, you will not be able to handle the tool.
Weka is a data mining tool with all the available mining algorithms. However, it does not handle multi-relational mining.
