... a feature probability to change smoothly and to be removed from the model only once its probability of occurrence is ...versus feature allocation modeling. At the same time, both models let features ... See full document

... Much previous work assumes that both lexical and prosodic cues are available for the task. Kim and Woodland (2001) performed punctuation inser- tion during speech recognition. Prosodic features to- gether with language ... See full document

... Feature selection is well established for many machine learn- ing methods, for instance for feed-forward neural networks [2] or decision trees [17]. The main advantages are an im- provement of prediction ... See full document

... Feature-based models like crfs are attractive since they reduce the problem to finding a feature set that adequately represents the target ... See full document

... parsing models have the potential to supplant the currently dominant lexicalized PCFG models for parsing by allowing much richer feature sets and simpler smoothing, while avoid- ing the label bias ... See full document

... Our multiscale spatiotemporal framework performs smoothing simultaneously in space and time. This point is made clear in Section 4, where we present results on the spatial and spatiotemporal dependence structures of our ... See full document

... We describe a new loss function, due to Jeon and Lin (2006), for estimating structured log-linear models on arbitrary features. The loss function can be seen as a (generative) al- ternative to maximum likelihood ... See full document

... Both αβ-swap and α-expansion only allow a variable to take one of two possible labels at each iteration. In other words, they are restricted to a small search space during each move. Gupta and Tardos (2000) extended the ... See full document

... Our first main result is Theorem 2.3, which characterizes the value of the con- strained Dynkin game and its associated optimal stopping strategy in terms of the solution of a penalized backward stochastic differential ... See full document

... As proposed here, the new theory is a theory of everything at the level of classical physics. This claim rests on the fact that both charge density and mass density are treated as dynamic fields in the ... See full document

... The remainder of the thesis is organized as follows: Chapter 2 describes a general rela- tion extraction system, its modules and previous works related to each module. Chapter 3 explains the idea behind semi-supervised ... See full document

... The ZIPG regression model had a closed form which finally ended in a negative binomial model while the ZIPLN regression model did not have a closed form and that is why its parameters estimating are more complex. On the ... See full document
