Miralium - Java implementation of Margin Infused Relaxed Algorithm

Margin Infused Relaxed Algorithm (MIRA), also called 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. For details, see: Crammer, K., Singer, Y. (2003): Ultraconservative Online Algorithms for Multiclass Problems. In: Journal of Machine Learning Research 3, 951-991. Our java implementation follows CRF++ file formats and can be used for part-of-speech t

This program is implementation of Conditional Neural Fields. Please refer to the paper for more information about CNF. Jian Peng, Liefeng Bo and Jinbo Xu. "Conditional Neural Fields". The 23rd Annual Conference on Neural Information Processing Systems (NIPS 2009) This program takes data files and template files and produces tagging files similar to those of Taku Kudo's CRF++ program described at <>. However hyperparameter of template has added to template file.
