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.
