I'm really fascinated with your comprehensive explanation and well-organized lectures. I just finished lesson first and got through well all the activities.
Prepared with academic book 'Data Mining' translated in Korean language,
I'm really looking forward to finish all of your lectures and did well untill lesson 1
Regretfully, I was stuck by of great obstacle at Lesson 2-1. That is I
couldn't find UserClassifier which seems to be essential at carrying on the lectures. My Weca version is now 3.81 and my computer runs with Window 7, however I couldn't find UserClassifier at program list where you get it in the video. I beg you to help me find UserClassfier or download it so that I can complete the rest of lectures
thoroughly. Thank you. Kim Yun Jae from Korea,
Extending Weka with "packages"
Weka has hundreds of different classifiers and scores of filtering algorithms. To simplify the interface, when you download Weka it comes with a small set of key classifiers and filters, along with a simple mechanism that allows you to add new methods that are stored in separate “packages”.
The Package Manager is accessed from the Tools menu in Weka’s GUI Chooser panel, which appears when you start up Weka:
The very first time it is accessed, the Manager downloads information about all available packages. This requires an internet connection.
Here is the resulting display:
The top half is a scrollable list of packages, beneath which is information about the currently selected package – in this case the userClassifier package.
To install (or uninstall) a package, click the install (or uninstall) button near the top of the window. When you do this, you will be asked to close any Weka application windows – like the Explorer. When you reopen it, the new package will be incorporated.
You can display all packages, or just the ones that are installed, or just the ones that are not installed. The list gives the package name, the broad category it belongs to, the version currently installed (if any), and the most recent version. It can be sorted, in ascending or descending order, by clicking the package or the category column header.
For successful operation the Package Manager requires Weka version 3.8.1 or later. If yours predates this you should install the latest version.
