To approximate the conditional log-likelihood a model seeks to maximize, the hierarchical softmax method uses a Huffman tree to reduce calculation. The negative sampling method, on the other hand, approaches the maximization problem by minimizing the log-likelihood of sampled negative instances.

Asynchronous learning is a general term used to describe forms of education, instruction, and learning that do not occur in the same place or at the same time. It uses resources that facilitate information sharing outside the constraints of time and place among a network of people. [ 1 ]
If the agents act together in solving a problem they can be viewed as knowledge sources in the blackboard problem-solving model." I would have to read more about the application the original author proposed. If the agents just use the system for communication, then I don't think such a system qualifies as a blackboard system.
