Empirical techniques

Paraphrase generation is an important task that has received a great deal of interest recently. Proposed datadriven solutions to the problem have ranged from simple approaches that make minimal use of NLP tools to more complex approaches that rely on numerous languagedependent resources. Despite all of the attention, there have been very few direct empirical evaluations comparing the merits of the different approaches.

We explore how active learning with Support Vector Machines works well for a nontrivial task in natural language processing. We use Japanese word segmentation as a test case. In particular, we discuss how the size of a pool affects the learning curve. It is found that in the early stage of training with a larger pool, more labeled examples are required to achieve a given level of accuracy than those with a smaller pool. In addition, we propose a novel technique to use a large number of unlabeled examples effectively by adding them gradually to a pool. ...

In a language generation system, a content planner embodies one or more “plans” that are usually hand–crafted, sometimes through manual analysis of target text. In this paper, we present a system that we developed to automatically learn elements of a plan and the ordering constraints among them. As training data, we use semantically annotated transcripts of domain experts performing the task our system is designed to mimic.

The favorable reception of Portfolio Management Formulas exceeded even the greatest expectation I ever had for the book. I had written it to promote the concept of optimal f and begin to immerse readers in portfolio theory and its missing relationship with optimal f. Besides finding friends out there, Portfolio Management Formulas was surprisingly met by quite an appetite for the math concerning money management. Hence this book. I am indebted to Karl Weber, Wendy Grau, and others at John Wiley & Sons who allowed me the necessary latitude this book required....

The second edition of "Model Predictive Control" provides a thorough introduction to theoretical and practical aspects of the most commonly used MPC strategies. It bridges the gap between the powerful but often abstract techniques of control researchers and the more empirical approach of practitioners. The book demonstrates that a powerful technique does not always require complex control algorithms. Many new exercises and examples have also been added throughout.

But up to now not only few but also rather inadequate empirical segmentation studies of these markets have been carri ed out and published. So, this book will present the results of a newer and better designed segmentation study of Chinese consumer goods markets. This study identifies and characterizes 12 market segments that are internally homogeneous and externally heterogeneous with regard to the product related needs and wants of their members. Moreover, it explains the possibilities of a segment specific tailoring of some other elements of the marketing mix.

It also reviews different valuation methods and estimated values for nonmarket forest goods and services in Europe. Chapter 5 gives an overview of the financing mechanisms used in the Member States and their applicability for different goods and services. It includes a theoretical review of alternative financing mechanisms for nonmarket forest goods and services (FG&S) as well as an empirical assessment of their use in Europe and EU Member States (EU MS).

We propose a twostep inversion of threecomponent seismograms that ( 1) recovers the farfield source time function at each station and (2) estimates the distribution of coseismic slip on the fault plane for small earthquakes (magnitude 3 to 4). The empirical Green’s function (EGF) method consists of finding a small earthquake located near the one we wish to study and then performing a deconvolution to remove the path, site, and instrumental effects from the mainevent signal.

The rest of the paper is organized as follows. Section I lays out the household’s consumption and portfolio choice problemwith a durable consumption good and derives the Euler equations. Section II describes the consumption data used in the empirical work. The service f low for durable goods (as defined in the national accounts) is more cyclical than the service f low for nondurable goods and services. The high cyclicality of the service f low, rather than durability of the good, is the key ingredient in explaining the known facts about expected stock returns....

A system making optimal use of available information in incremental language comprehension might be expected to use linguistic knowledge together with current input to revise beliefs about previous input. Under some circumstances, such an errorcorrection capability might induce comprehenders to adopt grammatical analyses that are inconsistent with the true input.

Fourth, the model provides a rational to the empirical nding that volatility factors are priced in the cross section of stock returns. In the current model, stock return volatility factors are driven by systematic risk factors: sentiment and solvency risks. These factors, which drive volatility factors, are shown to be priced across di¤erent stocks in an equilibrium consumption CAPM.

Instrumental variables techniques are required to solve the possible endogeneity of household consumption. The most difficult task is to find a valid instrument for the regression above. The literature on demand systems typically uses income to instrument consumption. If preferences are separable between consumption and leisure, total consumption but not income is relevant to decide on the good shares. However, there are several reasons why household income might not be a valid instrument.

While the stochastic volatility (SV) generalization has been shown to improve the explanatory power over the BlackScholes model, empirical implications of SV models on option pricing have not yet been adequately tested. The purpose of this paper is to ﬁrst estimate a multivariate SV model using the efﬁcient method of moments (EMM) technique from observations of underlying state variables and then investigate the respective effect of stochastic interest rates, systematic volatility and idiosyncratic volatility on option prices....
