Description
MIRA (Margin Infused Relaxed Algorithm), also named passive-aggressive algorithm (PA-I), is an extension of the perceptron algorithm for online machine learning that ensures that each update of the model parameters yields at least a margin of one.
This MIRA java implementation follows CRF++ file formats and can be used for part-of-speech tagging, chunking and other tagging tasks.
Compared to CRFs, mira is much faster to train at the cost of a little reduction in accuracy, which is very valuable for sequence classification tasks with many labels.
Detailed instructions on how to install and use the MIRA utility on your Mac are available HERE.
MIRA is a cross-platform utility capable of running on any operating system that comes with Java support (e.g. Mac OS X, Windows, Linux).
NOTE: Does not support valued features, n-best output and confidence scores yet.
