Evaluation of text summary is very essential issue of summarization. Normally, we can judge the relevance of any summary by applying extrinsic or intrinsic evaluation measures. Intrinsic evaluation techniques try to judge the relevance of any summary with evaluation by human experts. Extrinsic evaluation techniques judge quality of summary with task oriented techniques like task related to extr...

We develop and evaluate a novel data compression strategy for visual SLAM centered on traveled trajectory analysis. Beyond compressing scene structure based purely on geometrical information as commonly done, we aim at developing representations that are useful for re-exploration, that use low memory footprint and low CPU computation. Our work is evaluated on data collected from a visual sensor...

We present geometric simulations on a zeolite framework (faujasite) with extra-framework methanol and water contents explicitly present. We distinguish the intrinsic flexibility window of the framework from the newly defined extrinsic window limited by host-guest steric interactions. The extrinsic flexibility window can be limited not only in compression, but also in expansion, as the beta-cage...

We present Angle-Analyzer, a new single-rate compression algorithm for triangle-quad hybrid meshes. Using a carefully-designed geometry-driven mesh traversal and an efficient encoding of intrinsic mesh properties, AngleAnalyzer produces compression ratios 40% better in connectivity and 20% better in geometry than the leading Touma and Gotsman technique for the same level of geometric distortion...

In this work, a transition process in hypersonic flow over cold-wall compression ramp is studied using direct numerical simulation (DNS) and global stability analysis (GSA). The free-stream Mach number the Reynolds based on flat-plate length are 7.7 $8.6 \times 10^5$ , respectively. shock-induced pressure rise causes boundary layer to separate flat plate, forming separation bubble around corner...

Basilar impression is a skeletal malformation characterized by translocation of the upper cervical spine and clivus into the foramen magnum, giving rise to various symptoms related to brainstem, upper spinal cord, and cerebellar compression. It is generally classified as primary (familial), in which the defect is unaccompanied by intrinsic abnormalities of bone, or as secondary, reflecting an i...

General intelligence requires open-ended exploratory learning. The principle of compression progress proposes that agents should derive intrinsic reward from maximizing “interestingness”, the first derivative of compression progress over the agent’s history. Schmidhuber posits that such a drive can explain “essential aspects of ... curiosity, creativity, art, science, music, [and] jokes”, imply...

Internal stability of isotropic nonlinear elastic materials under homogeneous deformation is studied. Results provide new insight into various intrinsic stability measures, first proposed elsewhere, for generic nonlinear elastic solids. Three intrinsic stability criteria involving three different tangent elastic stiffness matrices are considered, corresponding to respective increments in strain...

BACKGROUND AND PURPOSE Acute markers of spinal cord injury are essential for both diagnostic and prognostic purposes. The goal of this study was to assess the relationship between early MR imaging biomarkers after acute cervical spinal cord injury and to evaluate their predictive validity of neurologic impairment. MATERIALS AND METHODS We performed a retrospective cohort study of 95 patients ...

The simple but general formal theory of fun & intrinsic motivation & creativity (1990-) is based on the concept of maximizing intrinsic reward for the active creation or discovery of novel, surprising patterns allowing for improved prediction or data compression. It generalizes the traditional field of active learning, and is related to old but less formal ideas in aesthetics theory and develop...
