چکیده
In this paper we analyze a variety of standard techniques used in corpus linguistics and examine a number of issues relating to incorrect usage, the computational infeasibility of various approaches, and the inevitable sampling errors. We motivate much of the paper with applications from information retrieval but the techniques discussed and introduced are far more widely applicable, and some are indeed motivated from other applications of corpus linguistics.

fMRI of the brainstem using dual-echo EPI
The brainstem is the part of the human brain that plays a pivotal role in the maintenance of many critical body functions. Due to the elevated level of cardiogenic noise, few fMRI studies have investigated the brainstem so far. Cardiac-gated echo-planar imaging with acquisition of two echoes per excitation (dual-echo EPI) is one method that significantly reduces cardiogenic noise and, thus, all...

متن کاملLocal Likelihood Estimation in Varying-coeecient Models including Additive Bias Correction
Varying coeecient models result from generalized linear models by allowing the parameter of the linear predictor to vary across some additional explanatory quantity called eeect modiier. While Hastie & Tibshirani (1993) have used spline smoothing techniques in varying-coeecient models with univariate response here the local likelihood approach is considered within the framework of multivariate ...
متن کاملDiscrimination of Golab apple storage time using acoustic impulse response and LDA and QDA discriminant analysis techniques
ABSTRACT- Firmness is one of the most important quality indicators for apple fruits, which is highly correlated with the storage time. The acoustic impulse response technique is one of the most commonly used nondestructive detection methods for evaluating apple firmness. This paper presents a non-destructive method for classification of Iranian apple (Malus domestica Borkh. cv. Golab) according...
متن کاملNon-linear Normalization and Background Correction in One-channel CDNA Microarray Studies
MOTIVATION Data from one-channel cDNA microarray studies may exhibit poor reproducibility due to spatial heterogeneity, non-linear array-to-array variation and problems in correcting for background. Uncorrected, these phenomena can give rise to misleading conclusions. RESULTS Spatial heterogeneity may be corrected using two-dimensional loess smoothing (Colantuoni et al., 2002). Non-linear bet...
