source code

Tools for writing and reading classifier example files

These functions read and write machine learning example files and convert examples into final data forms. The memory representation for each example is a 4-tuple (or list) of the format: (id, class, features, extra). id is a string, class is an int (-1 or +1 for binary) and features is a dictionary of int:float -pairs, where the int is the feature id and the float is the feature value. Extra is a dictionary of String:String pairs, for additional information about the examples.
