I am still working on the upcoming version of SPMF. There is still much work todo. Following the previous post, I would like to give you a glimpse of the new visual pattern viewer that is under development for SPMF. This is a new tool that will allow to see patterns visually and search and filter them. It will be well-designed and will work with most pattern types that can be produced by SPMF. Here is a picture of the current version:
On that picture we can see a list of high utility sequential patterns displayed as a grid, where the utility of each pattern is displayed using a colored bar that varies from 0 to the maximum utility observed among the patterns in this example, which is 40. On the right, there is a search panel to filter the pattern by utility values or to search for a specific itemsets. In this example, only the patterns with a utility of at least 37 are displayed using the filter. In the menu bar, we can also sort the patterns by different orders:
For example, above the patterns were displayed by decreasing number of itemsets. We can change this to display them by ascending utility, and remove the filters, to obtain this:
Now, let me show you other pattern types. Here are high utility sequential rules:
And here are frequent high utility itemsets:
Update: I have fixed the alignment of colored bars representing measures. And the different measures are now displayed with different colors:
Conclusion
This is just an overview of this upcoming tool that will be incorporated in the new version of SPMF. If you have suggestions, please leave a comment below. Note also that this tool is under development. The released version may be different and have additional features.
