A Bottom-Up Exploration of the Dimensions of Dialog State in Spoken Interaction
"... Taxonomies of dialog state are important, both scientifically and practically, but today’s best build strongly on tradition. This paper presents a new way to discover the important dimensions of dialog state, more bottomup and empirical than previous approaches. Specifically, we applied Principal Co ..."

Loopy belief propagation for approximate inference: An empirical study. In:
- Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

. For each experimental run, we first gen erated random CPTs. We then sampled from the joint distribution defined by the network and clamped the observed nodes (all nodes in the bottom layer) to their sampled value. Given a structure and observations, we then ran three inference algorithms -junction tree
Bottom-Up Accountability and the Tsunami
"... This paper explores specific examples of ‘bottom-up ’ accountability related to the Tsunami response with particular reference to Sri Lanka. Examples include local and camp-level processes as well as attempts to scale-up these approaches at district, and national levels. This experience is related t ..."

Bottom-up Analysis
, 2001
"... On its way to its current form this report has received significant input from a considerable number of experts. In particular, a panel of experts in Brussels discussed a draft version of the report on March 29, 2000 (see Annex 5 for a list of names), and made a number of specific and more general c ..."

Bottom-up model-driven development
- In Proceedings of the International Conference on Software Engineering (ICSE’13
, 2013
"... Abstract-Prominent researchers and leading practitioners are questioning the long-term viability of model-driven development (MDD). Finkelstein recently ranked MDD as a bottomten research area, arguing that an approach based entirely on development and refinement of abstract representations is unte ..."

This paper reports on recent work that suggests this approach
Bottom-Up Beats Top-Down
"... In PEPA, the calculation of the transitions enabled by a process accounts for a large part of the time for the state space exploration of the underlying Markov chain. Unlike other approaches based on recursion, we present a new technique that is iterative—it traverses the process ’ binary tree from ..."

Bottom-up generalization: a data mining solution to privacy protection
- In ICDM
, 2004
"... The well-known privacy-preserved data mining modifies existing data mining techniques to randomized data. In this paper, we investigate data mining as a technique for masking data, therefore, termed data mining based privacy protection. This approach incorporates partially the requirement of a targe ..."

Bottom–Up Excitable Models of Phytoplankton Blooms
"... A simple nutrient–phytoplankton model is used to explore the dynamics of phyto-plankton blooms. The model exhibits excitable behaviour in the sense that a large scale outbreak can only be triggered when a critical nutrient threshold is exceeded. The model takes into account several features often ne ..."

neglected but whose combined effect proves very important: (i) rapid nutrient recycling associated with the micro-bial loop and patch formation; (ii) self-shading; and (iii) a bottom–up approach, whereby nutrient levels are responsible for both the triggering and the demise of the bloom. Although
A Bottom-up approach to the cultural evolution of bilingualism
"... The relationship between individual cognition and cultural phenomena at the society level can be transformed by cultural transmission (Kirby, Dowman, & Griffiths, 2007). Top-down models of this process have typically assumed that individuals only adopt a single linguistic trait. Recent extensio ..."

Exploring the Relative Role of Bottom-up and Topdown Information in Phoneme Learning
- In Proceedings of the 52nd Annual Meeting of the Association for Computational Linguistics
, 2014
"... We test both bottom-up and top-down ap-proaches in learning the phonemic status of the sounds of English and Japanese. We used large corpora of spontaneous speech to provide the learner with an input that models both the linguistic properties and statistical regularities of each language. We found b ..."
