Deep learning is providing very positive results in areas related to conversational interfaces, such as
speech recognition, but its potential benefit for dialog management has still not been fully studied. In
this paper, we perform an assessment of different configurations for deep-learned dialog management
with three dialog corpora from different application domains and varying in size, dimensionality
and possible system responses. Our results have allowed us to identify several aspects that can have
an impact on accuracy, including the approaches used for feature extraction, input representation,
context consideration and the hyper-parameters of the deep neural networks employed.
