This paper introduces a new discriminative model for image annotation. To learn the discriminative model, our method divides each training image into patches, and embeds the patches into a hypergraph, so as to find the representative instances (also called exemplars) for every single class by solving the graph. Then, the feature differences between the training samples and the exemplars are use...

This paper presents a spectral clustering method called correlation through preserving indexing (CPI), which is to perform in the correlation similarity measure space. The documents are considered into a low dimensional semantic space, the correlations between the documents in the local patches are maximized and correlations between the documents outside these patches are minimized. The intrins...

We introduce new Bézier-like formulas with quaternionic weights for rational curves and surfaces in Euclidean 3-space. They are useful for representation of Möbius invariant geometric objects. Any Bézier curves and surfaces on 2-spheres can be converted to the quaternionic Bézier (QB) form of twice lower degree. Our focus is on bilinear QB-surfaces: we derive their implicitization formula and s...

We recently introduced an efficient technique for out-of-core rendering and management of large textured landscapes. The technique, called Batched Dynamic Adaptive Meshes (BDAM), is based on a paired tree structure: a tiled quadtree for texture data and a pair of bintrees of small triangular patches for the geometry. These small patches are TINs that are constructed and optimized off-line with ...

The role of adherent-invasive E. coli (AIEC) in Crohn disease (CD) has been in debate for decades. AIEC bacteria are found in the small intestine of patients with chronic CD, but it has remained unclear whether this infection is causal or secondary to underlying immune deficiencies in CD patients. In this issue of the JCI, Chassaing and colleagues demonstrate that AIEC bacteria express an adher...

Previous history.?The child was first noticed to be ill early on the morning of the 4th May, when she refused food and complained of a pain in her throat. Her mother then recognised that she was feverish, and saw some white or grey patches on the tonsils. Nothing alarming occurred until the night of the 7th May when the child suddenly developed symptoms of choking, dyspnoea and great restlessne...

In this paper, a supervised energy disaggregation method is proposed. The appliances to be monitored, are modelled by multi-state finite state machines. Each state of an appliance is described by exactly one vector of power consumptions from a carefully designed set of such vectors (called atoms), that comprise a dictionary. The latter is constructed during a training phase, where it is assumed...

In terms of machine learning theory, the intrinsic geometrical structure of the original data space is usually embedded in the low-dimensional manifold. The extraction of optimized manifold features could improve the performance of clustering. This paper presents a new spectral clustering method called local topology preserving indexing (LTPI). In this algorithm, the data are projected into a l...

In many JPEG image splicing forgeries, the tampered image patch has been JPEG-compressed twice with different block alignments. Such phenomenon in JPEG image forgeries is called the shifted double JPEG (SDJPEG) compression effect. Detection of SDJPEG-compressed patches could help in detecting and locating the tampered region. However, the current SDJPEG detection methods do not provide satisfac...
