We first present an improvement of Kanatani’s subspace separation [8] for motion segmentation by newly introducing the affine space constraint . We point out that this improvement does not always fare well due to the effective noise it introduces. In order to judge which solution to adopt if different segmentations are obtained, we present two criteria: one is the standard F test; the other is ...

What has science actually achieved? A theory of achievement should (1) define what has been achieved, (2) describe the means or methods used in science, and (3) explain how such methods lead to such achievements. Predictive accuracy is one truth-related achievement of science, and there is an explanation of why common scientific practices (of trading off simplicity and fit) tend to increase pre...

Recent surveys have shown that an increasing portion of the US public believes the two major US parties inadequately represent the US public opinion, and think additional parties are needed [1]. However, there are high barriers for third parties in political elections. In this paper, we aim to address two questions: “How well do the two major US parties represent the public’s ideology?” and “Do...

This report reviews and straightens methodologies to explore functional forms of man-landcover interrelations**. Tanaka and Nishii[7, 8, 9, 10, 12, 13], Nishii and Tanaka[4, 6], Nishii, Miyata, and Tanaka[5] have engaged in the analysis of deforestation by human population interactions. The basic strategy has been to use landcover data mashed up with cell-formed population density data. Two fac...

The objectives of this study were: (i) to compare five models (Wood, Cobby & Le Du, Wilmink, Cappio Borlino, Djikstra) for describing the lactation curve of Chios sheep, (ii) to identify variation in lactation parameters related to environmental factors (season) and animal factors (parity). A data base on 61,705 recordings of daily milk production obtained from an automatic milking system was u...

A wide range of blind source separation methods have been used in motor control research for the extraction of movement primitives from EMG and kinematic data. Popular examples are principal component analysis (PCA), independent component analysis (ICA), anechoic demixing, and the time-varying synergy model (d'Avella and Tresch, 2002). However, choosing the parameters of these models, or indeed...

The epistemic weight of simplicity in science has, in the last fifteen years, been extensively discussed in the framework of statistical model comparison. This paper defends three theses: First, it juxtaposes Forster and Sober’s (1994, 2010) claims regarding the normative force of Akaike’s Theorem in statistical model analysis. Second, it elaborates the different targets of the various model co...

Learning technology standards are increasingly gaining in importance in the field of Web-based teaching. At present, two standards dominating the market are taking shape. These are the SCORM standard of the ADL initiative and the AICC standard of the AICC organization. Based on the AICC and LOM meta data standards, the SCORM standard stands the chance to become the standard dominating the marke...

This paper aims to propose a bootstrap method for characterizing the effect of uncertainty in shear strength parameters on slope reliability. The procedure for a traditional slope reliability analysis with fixed distributions of shear strength parameters is presented first. Then, the variations of the mean and standard deviation of shear strength parameters and the Akaike Information Criterion ...
