SPMF data mining library 0.98: new pattern visualization window

This blog post is to let you know that I have just published a new version of the SPMF open-source Java data mining library (0.98) that offers a new window for visualizing the patterns found by data mining algorithms. This window should be more convenient to use than the text editor for visualizing results as it offers sorting and filtering functions. Here is a picture:

This window is specifically designed for visualizing patterns found by pattern mining algorithms. But it also work with some algorithms such as clustering algorithms, also offered in SPMF.

How to access this new window? This window can be accessed when using the graphical interface of SPMF by selecting the checkbox “Open output file” “using SPMF viewer“. The new window show the patterns found by an algorithm in a table, and it let the user apply some filters to select patterns or to sort the patterns by ascending or descending orders using various measures such as support and confidence (depending on the algorithms) by clicking on the column headers.

This window for visualizing patterns should work with most algorithms offered in SPMF. If you find some bugs related to this new window for visualizing results, you may let me know. Also, if you have some ideas to improve, or want to participate to improve the user interface of SPMF, you may let me know.

Hope you will like it! Also, thanks again to all users of SPMF for your support.
