Jerome Friedman, Trevor Hastie and Robert Tibshirani: Regularized Paths for Generalized Linear Models via Coordinate Descent. We use coordinate descent to develop regularization paths for linear, logistic and multinomial regression models. Our algorithms use the lasso and "elastic net" penalties of Zou and Hastie (2005), and create the path for a grid of values of the penalty parameter lambda. The glmnet package for fitting Lasso and elastic net models can be found on CRAN . Here is a MATLAB version .

Friedman, J., Hastie, T. and Tibshirani, R "Additive Logistic Regression: a Statistical View of Boosting". Tech. report July 23, 1998 . We show that boosting fits an additive logistic regression model by stagewise optimization of a criterion very similar to the log-likelihood, and present likelihood based alternatives. We also propose a multi-logit boosting procedure which appears to have advantages over other methods proposed so far. Tibshirani, R "Learning from Data: Statistical Advances and Challenges".

Indeed, a simple modification to backfitting turns it into a Gibbs sampler for spitting out samples from the "posterior" distribution for an additive fit.
