Weierstraß-Institut für Angewandte Analysis und Stochastik Adaptive smoothing as inference strategy: More specificity for unequally sized or neighboring regions

Marijke Welvaert, Karsten Tabelow, Ruth Seurinck, Yves Rosseel
unpublished
CONCLUSIONS More advanced adaptive smoothing procedures can be used as an inference strategy to obtain more specificity for example with unequally sized or neighbouring regions.  ...  In this paper we focused on two specific scenarios often encountered in fMRI research, namely (1) activation in unequally sized regions and (2) activation in neighbouring regions.  ...

Five dichotomies in the psychophysics of ensemble perception

Joshua A. Solomon
2020 Attention, Perception & Psychophysics  
Modeling decisions about prothetic continua, such as size and contrast, can be tricky because sensory signals may be distorted before and/or after voluntarily computing ensemble statistics.  ...  Conversely, when asked to make a (voluntary) decision about the ensemble as a whole, observers may find it very difficult to compute statistics that are based on more than a very small number of individual  ...  Alternatively, noninteger values of M might reflect an unequal weighting of two or more of the texture elements. 2 The smooth curve in Fig. 5d illustrates a slightly different noisy, inefficient observer  ...

Use of remotely sensed auxiliary data for improving sample-based forest inventories

Svetlana Saarela
2015 Dissertationes Forestales  
Empirical data for the studies were acquired from a boreal forest area in the Kuortane region of western Finland.  ...  As for the choice of inferential framework, it was revealed that model-based inference in this case had some advantages compared to design-based inference through model-assisted estimators.  ...  The NN estimator becomes more efficient with unequal probabilities compared with equal probabilities when the sample size increases, and this effect comes at a smaller sample size for LPM 3 * versus LPM  ...

Learning Timbre Analogies from Unlabelled Data by Multivariate Tree Regression

Dan Stowell, Mark D. Plumbley
2011 Journal of New Music Research  
Standard query techniques such as nearest neighbours do not account for this difference between source and target; they perform retrieval but do not learn to make timbral analogies.  ...  -for example when using vocal queries to retrieve nonvocal sound.  ...  An issue that affects our choice of search strategy is whether the timbral analysis should best be treated as absolute and contextindependent, or whether it should be treated as relative -for example,  ...
