The Glass Dataset
The glass dataset glass.arff from the U.S. Forensic Science Service contains data
on six types of glass. Glass is described by its refractive index and the chemical
elements that it contains; the the aim is to classify different types of glass based
on these features. This dataset is taken from the UCI datasets, which have been
collected by the University of California at Irvine and are freely available on
the Web. They are often used as a benchmark for comparing data mining
algorithms.
Find the dataset glass.arff and load it into the Explorer interface. For your own
information, answer the following exercises, which review material covered in the
previous section.
Exercise 17.2.1. How many attributes are there in the dataset? What are
their names? What is the class attribute? Run the classification algorithm
IBk (weka.classifiers.lazy.IBk). Use cross-validation to test its performance,
leaving the number of folds at the default value of 10. Recall that you can
examine the classifier options in the Generic Object Editor window that
pops up when you click the text beside the Choose button. The default
value of the KNN field is 1: This sets the number of neighboring instances
to use when classifying.

CCD glass Glass.arff Forensic Science Service glass series from the United States include information on the type of glass refractive index of glass is described by the chemical elements that include the aim of. The type of glass used in these features, the series is taken from datasets UCI, which was compiled by the University of California at Irvine and is available freely on the Web , often used as a benchmark to compare to. Data mining algorithms to find glass.arff datasets and loaded into an Internet interface. Explorer for your own information, The following exercise Which examined the material covered in the answer to the previous section 17.2.1. The exercise of any attributes of the data set is a class attribute is running the algorithm classified IBk. (Weka.classifiers.lazy.IBk) is used to monitor the performance test out of the fold of a default. 10 Recall that you can check the classifier in Editor window objects that appear when you click on the button to select the default value of the field KNN is one: this is the number of instances that close.
