 ## Purpose
@@ -17,7 +21,11 @@ BayesML has the following characteristics.
 * Many of our learning algorithms are much faster than general-purpose Bayesian learning algorithms such as MCMC methods because they effectively use the conjugate property of a probabilistic data generative model and a prior distribution. Moreover, they are suitable for online learning.
 * All packages have methods to visualize the probabilistic data generative model, generated data from that model, and the posterior distribution learned from the data in 2~3 dimensional space. Thus, you can effectively understand the characteristics of probabilistic data generative models and algorithms through the generation of synthetic data and learning from them.
