weka - Making predictions

weka - Making predictions: "Classifiers
After a model has been saved, one can make predictions for a test set, whether that set contains valid class values or not. The output will contain both the actual and predicted class. (Note that if the test class contains simply '?' for the class label for each instance, the "actual" class label for each instance will not contain useful information, but the predicted class label will.) The "-T " command-line switch specifies the dataset of instances whose classes are to be predicted, while the "-p " switch allows the user to write out a range of attributes (examples: "1-2" for the first and second attributes, or "0" for no attributes). Sample command line:

java weka.classifiers.trees.J48 -T unclassified.arff -l j48.model -p 0"

weka - Saving and loading models

weka - Saving and loading models: "You save a trained classifier with the -d option (dumping), e.g.:
java weka.classifiers.trees.J48 -t /some/where/train.arff -d /other/place/j48.model
And you can load it with -l and use it on a test set, e.g.:
java weka.classifiers.trees.J48 -l /other/place/j48.model -T /some/where/test.arff"

search - Ukkonen's suffix tree algorithm in plain English? - Stack Overflow: "The algorithm works in steps, from left to right. There is one step for every character of the string. Each step might involve more than one individual operation, but we will see (see the final observations at the end) that the total number of operations is O(n)."
