The paper introduces a hierarchical reinforcement learning framework called Feudal Networks (FuN) that enables agents to learn a hierarchy of temporal abstractions. The proposed model consists of a Manager and a Worker, with the Manager learning high-level policies and the Worker learning low-level policies. The approach is demonstrated to achieve state-of-the-art performance on a range of challenging tasks in the Atari domain.

In machine learning, boosting is an ensemble meta-algorithm for primarily reducing bias, and also variance in supervised learning, and a family of machine learning algorithms that convert weak learners to strong ones. Wikipedia

Naive Bayes classifiers are highly scalable, requiring a number of parameters linear in the number of variables (features/predcitors) in a learning problem. Maxumum-likelihood training can be done by evaluting a closed-form exporession, which takes linear time, rather tahn by expensive iterative approximation as used for many other typs of classifier.
