Language modeling is a difficult problem for languages with rich morphology. In this paper we investigate the use of morphology-based language models at different stages in a speech recognition system for conversational Arabic. Classbased and single-stream factored language models using morphological word representations are applied within an N-best list rescoring framework. In addition, we exp...

This paper investigates a novel statistical approach to music classification that utilizes recent technology developed in the domain of natural language processing. Specifically, we investigate the use of factored language models (FLMs) for the task of producing conditional probability distributions to model origin-specific folk songs. In our model, pitch cluster and quantized duration are empl...

Decentralized partially observable Markov decision processes (DEC-POMDPs) are used to plan policies for multiple agents that must maximize a joint reward function but do not communicate with each other. The agents act under uncertainty about each other and the environment. This planning task arises in optimization of wireless networks, and other scenarios where communication between agents is r...

Concern has recently arisen about the potential adverse effects of excessive calcium intakes, i.e., calcium loading from supplements, on arterial calcification and risks of cardiovascular diseases (CVD) in older adults. Published reports that high calcium intakes in free-living adults have relatively little or no beneficial impact on bone mineral density (BMD) and fracture rates suggest that cu...
