Today, I want to talk to give you a glimpse about some additional improvements in the upcoming version 2.66 of the SPMF pattern mining software, which will be released very soon. In this version, I have improved the Workflow editor. It is a tool that let the user create workflows with more than one algorithm, and then to run them.
Previously, the workflows had to be linear, that is only a sequence of algorithms could be created without branching. For example, there three algorithms (in red color) are run one after the other:
In SPMF 2.66, the user can now create workflows that are not linear. In other words, the workflows can have multiple branches (the output of an algorithm can be reused by multiple algorithms. Thus, it will now be possible to create more complex workflows like this:
In this example, an algorithm is applied to generate a transaction dataset “Output1.txt”. Then, this output is used by two algorithms, namely Eclat and FP-Growth, and for each of them, a different tools are used to visualize the results.
In SPMF 2.66, the Workflow editor has also other user interface improvements such as letting you choose recent files that you have previously used:
Moreover, there is now a new algorithm selection dialog that let you search algorithms and browse them by categories, which is more easy to use than the previous combo box of algorithms:
That is all for today! I just wanted to show some preview of other upcoming features in SPMF 2.66.
