The common uncertain sampling approach searches for the most uncertain samples closest to the decision boundary for a classification task. However, we might fail to find the uncertain samples when we have a poor probabilistic model. In this work, we develop an active learning strategy called “Uncertainty Sampling with Biasing Consensus” (USBC) which predicts the unbalanced data by multi-model c...

The boundary between Cretaceous and Paleogene (K/Pg) plays an important role in deciphering the Earth’s history biological evolution from Mesozoic to Cenozoic. As such, delineation characterization of layer has attracted significant attention. In this study, X-ray diffraction (XRD) elemental analyses were conducted characterize samples layers around Agost Caravaca, Spain. XRD results showed tha...

The Nanxiong Basin (Guangdong Province, China) preserves the most complete Asian stratigraphic record of the Cretaceous-Paleogene (K/Pg) boundary extinction and the subsequent Paleocene mammalian radiation. Despite extensive study, the precise placement of the K/Pg boundary in the Nanxiong Basin sequence has been controversial, and the timing of subsequent mammalian turnover is poorly constrain...

An iterative procedure for numerical conformal mapping is presented which imposes no restriction on the boundary complexity. The formulation involves two analytically equivalent boundary integral equations established by applying the conjugation operator to the real and the imaginary parts of an analytical function. The conventional approach is to use only one and ignore the other equation. How...

This paper presents a methodology to calculate probabilities of failure using Probabilistic Support Vector Machines (PSVMs). Support Vector Machines (SVMs) have recently gained attention for reliability assessment because of several inherent advantages. Specifically, SVMs allow one to construct explicitly the boundary of a failure domain. In addition, they provide a technical solution for probl...

This paper proposes a post-processing technique for reducing tile boundary artifacts which occur in an image when it is compressed at low bit rate using JPEG2000 standard. Symmetric extension and difference in quantization accuracy between the tiles of the image are the main factors behind the tile boundary artifacts in JPEG2000 compressed images. In this paper, we have analyzed the effect of q...

It is a scientist’s mission to try to remain unbiased. However, certain factors play a role in scientific analyses that are not controlled by conscious thought. These factors are potentially very important in areas of science where interpretations are based on a scientist’s ability to identify patterns or structures. One such area is the micromorphology of glacial sediments. In this paper we in...

The aim of this paper is to locate the boundary defects such as open, short, mousebite, and spur on Ball Grid Array (BGA) substrate conduct paths using machine vision. The 2-D boundaries of BGA substrate conduct paths are initially represented by the 1-D tangent angles. The tangent angles are evaluated from the covariance matrix eigenvector over a region of support on a boundary segment. Bounda...
