Taking Strategies to Task

Taking Strategies to Task

In this issue of Neuron, Uka and DeAngelis report a neural signature of the strategy that monkeys' brains developed to solve a visual discrimination task by training them on one version of the task and testing them on another. Extensive training on one version caused decision networks in the animals' brains to ignore certain classes of neurons whose signals would have been useful on the modifie...

Great Apes' Risk-Taking Strategies in a Decision Making Task

We investigate decision-making behaviour in all four non-human great ape species. Apes chose between a safe and a risky option across trials of varying expected values. All species chose the safe option more often with decreasing probability of success. While all species were risk-seeking, orangutans and chimpanzees chose the risky option more often than gorillas and bonobos. Hence all four spe...

Applications of Evolutionary Strategies to FineGrained Task

Embedding task graphs into hypercubes is a diicult problem. When the embedding is one-to-one, schedule length is strongly innuenced by dilation. Therefore, it is desirable to nd low dilation embeddings. This paper describes a heuristic embedding technique based upon evolutionary strategies. The technique has been extensively investigated using task graphs which are trees, forests, and butterrie...

Turn-taking cues in task-oriented dialogue

As interactive voice response systems become more prevalent and provide increasingly more complex functionality, it becomes clear that the challenges facing such systems are not solely in their synthesis and recognition capabilities. Issues such as the coordination of turn exchanges between system and user also play an important role in system usability. In particular, both systems and users ha...
