%global _description %{expand:
BayesML contributes to wide society thourgh promoting education, research, and
application of machine learning based on Bayesian statistics and Bayesian
decision theory.

Characteristics
Easy-to-use:
You can use pre-defined Bayesian statistical models by simply importing it. You
don't need to define models yourself like PyMC or Stan.

Bayesian Decision Theoretic API:
BayesML's API corresponds to the structure of decision-making based on Bayesian
decision theory. Bayesian decision theory is a unified framework for handling
various decision-making processes, such as parameter estimation and prediction
of new data. Therefore, BayesML enables intuitive operations for a wider range
of decision-making compared to the fit-predict type API adopted in libraries
like scikit-learn. Moreover, many of our models also implement fit-predict
functions.

Model Visualization Functions:
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.

Fast Algorithms Using Conjugate Prior Distributions:
Many of our learning algorithms adopt exact calculation methods or variational
Bayesian methods that effectively use the conjugacy between probabilistic data
generative models and prior distributions. Therefore, they are much faster than
general-purpose MCMC methods and are also suitable for online learning.
Although some algorithms adopt MCMC methods, but they use MCMC methods
specialized for each model, taking advantage of conjugacy.}
