Classification of surface pavement cracks as top-down, bottom-up, and cement-treated reflective cracking based on deep learning methods

Counter-Based Power Modeling Methods: Top-Down vs. Bottom-Up

Counter-based power models have attracted the interest of researchers because they became a quick approach to know the insights of power consumption. Moreover, they allow to overpass the limitations of measurement devices. In this paper, we compare different Top-down and Bottom-up Counter-based modeling methods. We present a qualitative and quantitative evaluation of their properties. In additi...

Top-down and bottom-up influences on learning from animations

To evaluate how top-down and bottom-up processes contribute to learning from animated displays, we conducted four experiments that varied either in the design of animations or the prior knowledge of the learners. Experiments 1–3 examined whether adding interactivity and signaling to an animation benefits learners in developing a mental model of a mechanical system. Although learners utilized in...

Event-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces

Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...

FaceTag: Integrating Bottom-up and Top-down Classification

Facetag is a working prototype of a semantic collaborative tagging tool conceived for bookmarking information architecture resources. It aims to show how the widespread homogeneous and flat keywords' space of tags can be effectively mixed with a richer faceted classification scheme to improve the “information scent” and “berrypicking” capabilities of the system. The additional semantic structur...
