Bayesian Nonparametrics – Stats and Bots

Bayesian Nonparametrics is a class of models with a potentially infinite number of parameters. High flexibility and expressive power of this approach enables better data modelling compared to parametric methods. Bayesian Nonparametrics is used in problems where a dimension of interest grows with data, for example, in problems where the number of features is not fixed but allowed to vary as we observe more data. Another example is clustering where the number of clusters is automatically inferred from data. The Statsbot team asked a data scientist, Vadim Smolyakov, to introduce us to Bayesian Nonparametric models.
