Parametric models

It is well known that occurrence counts of words in documents are often modeled poorly by standard distributions like the binomial or Poisson. Observed counts vary more than simple models predict, prompting the use of overdispersed models like GammaPoisson or Betabinomial mixtures as robust alternatives. Another deﬁciency of standard models is due to the fact that most words never occur in a given document, resulting in large amounts of zero counts. We propose using zeroinﬂated models for dealing with this, and evaluate competing models on a Naive Bayes text classiﬁcation task.

We propose a nonparametric Bayesian model for unsupervised semantic parsing. Following Poon and Domingos (2009), we consider a semantic parsing setting where the goal is to (1) decompose the syntactic dependency tree of a sentence into fragments, (2) assign each of these fragments to a cluster of semantically equivalent syntactic structures, and (3) predict predicateargument relations between the fragments.

In this paper we propose a method for the automatic decipherment of lost languages. Given a nonparallel corpus in a known related language, our model produces both alphabetic mappings and translations of words into their corresponding cognates. We employ a nonparametric Bayesian framework to simultaneously capture both lowlevel character mappings and highlevel morphemic correspondences.

In this paper* I will argue for a model of grammatical processing that is based on uniform processing and knowledge sources. The main feature of this model is to view parsing and generation as two strongly interleaved tasks performed by a single parametrized deduction process. It will be shown that this view supports flexible and efficient natural language processing.

The paper presents a language model that develops syntactic structure and uses it to extract meaningful information from the word history, thus enabling the use of long distance dependencies. The model assigns probability to every joint sequence of wordsbinaryparsestructure with headword annotation. The model, its probabilistic parametrization, and a set of experiments meant to evaluate its predictive power are presented.

The paper describes an experimental model of syntactic structure generation starting from the limited fragment of semantics that deals with the quantitative values of object parameters. To present the input information the basic semantic units of four types are proposed:"object", "parameter", "function" and "constant".

Since the publication of my book Mathematical Statistics (Shao, 2003), I have been asked many times for a solution manual to the exercises in my book. Without doubt, exercises form an important part of a textbook on mathematical statistics, not only in training students for their research ability in mathematical statistics but also in presenting many additional results as complementary material to the main text.

Chapter 13b: Answer key about COST MANAGEMENT 1. Answer: c Both the cost and accuracy of parametric models vary widely. They are most likely to be reliable when the historical information used to develop the model was accurate, the parameters used in the model are readily quantiﬁable, and the model is scalable (i.e., it works as well for a very large project as for a very small one). 2. Answer: b An analogous estimate is one that is arrived at by taking a project or part of a project that is already completed and adjusting the cost on the basis...

Knowing that the plant parameters can vary within their lower and upper bounds, this parametric uncertainty is formulated as an additive perturbation in the transfer function matrix. It is important to note that the controller be designed with respect to worst case uncertainty for each λij. This can be achieved by performing an optimization procedure given by (61) for 200 frequencies. Here an element by element uncertainty bound model is used for the characterization of upper bound of the uncertainty matrix. Then wij , which satisfies (62) for each λij is given in matrix form as,...

Estimation theory gives one approach to characterizing random variables. This was based on building parametric models and describing the data by the parameters. An alternative approach is given by information theory. Here the emphasis is on coding. We want to code the observations. The observations can then be stored in the memory of a computer, or transmitted by a communications channel, for example.
