Algorithm & Analysis
I analyzed the abalone data using decision trees built using Weka’s implementation of C4.5, with the intent of being able to predict the number of rings on an abalone shell from other characteristics, given data from the University of California, Irvine.
Decision trees yield discrete values, not numbers. So, in order to train the tree, I algorithmically binned the ring counts such that each bin had an approximately equal number of samples.
Since the number of rings is a fundamentally numeric attribute, I concluded that root-mean-square error (RMS error) was the best method for calculating accuracy. However, a decision tree cannot give the numeric values necessary for such a metric. Therefore, in order to test accuracy on each decision tree, I converted the bins back into numbers by considering a classification of a sample into an interval as the midpoint of the interval. If either bound of the interval was infinite, I used the other bound instead. So, if a sample had 8 rings and was classified as having a number of rings in [8.5, 9.5), the predicted number of rings would be considered to be 9; thus, there would be an error of -1. This would be squared and averaged with other such squared errors, and the total error would be the square root of that.
Training and testing was done by training on a random 90% of the data and testing on the remaining 10%. This may be iterated an arbitrary number of times to yield different, possibly better, trees. While training, I allowed the decision tree engine (J48) to prune to reduce error. This seems to have worked.

In order to maximize performance, I searched for the number of bins that would, yield the least error averaged over multiple iterations of training and testing. In order to do this, I first ran a small (20) number of iterations with each of the possible number of bins. The difference between the error of the best (8 bins) and second best (6 bins) was ~0.03, while the sample standard deviation was near 0.14. In order to get means that could be statistically distinguished with over 99.7% confidence, I needed to have enough samples that the standard deviation of the means was less than one third of difference the two lowest means. Since the standard deviation of the mean is the sample standard deviation divided by the square root of the number of samples, the number of required observations was the solution to , that is, 196. However, I did the math wrong, but that was okay, as I decided to use 300 trials, which was better. Doing 300 iterations resulted in Table 1, wherein it can be seen that 8 is the best number of bins. As such, it can be stated with better than 0.9999999 confidence that this is the best value.
