Parallelizing Top-Down Interprocedural Analyses

by Aditya V. Nori, Sriram Rajamani, Available Aditya, V. Nori, Aws Albarghouthi, Rahul Kumar, Aditya V. Nori, Sriram K. Rajamani
"... Modularity is a central theme in any scalable program analysis. The core idea in a modular analysis is to build summaries at proce-dure boundaries, and use the summary of a procedure to analyze the effect of calling it at its calling context. There are two ways to perform a modular program analysis: ..."

-alyzing each procedure in its calling context. Top-down analyses have several applications in verification and software model check-ing. However, traditionally, bottom-up analyses have been easier to scale and parallelize than top-down analyses. In this paper, we propose a generic framework, BOLT, which

An integrated model of top-down and bottom-up attention for optimal object detection

by Vidhya Navalpakkam - Proc. IEEE Conference on Computer Vision and Pattern Recognition (CVPR , 2006
"... Integration of goal-driven, top-down attention and image-driven, bottom-up attention is crucial for visual search. Yet, previous research has mostly focused on models that are purely top-down or bottom-up. Here, we propose a new model that combines both. The bottom-up component computes the visual s ..."

Combining bottom-up and top-down attentional influences

by Vidhya Navalpakkam, Laurent Itti
"... Visual attention to salient and relevant scene regions is crucial for an animal’s survival in the natural world. It is guided by a complex interplay of at least two factors – image-driven, bottom-up salience [1] and knowledge-driven, top-down guidance [2, 3]. For instance, a ripe red fruit among gre ..."

and intensities) at mul-tiple spatial scales in a manner described in [6]. Next, the top-down component uses learnt statistical knowledge of the local features of the target and distracting clutter, to optimize the relative weights of the bottom-up maps such that the overall salience of the target is maximized

Title: A Top-down Approach to Fundamental Interactions

by H. Barbee , 2012
"... Accurate estimates regarding the number of neutrons in the universe are now available due to the COBE, WMAP [8] and PLANCK projects. There are approximately the natural number e (2.71828) to the power 180 (exp(N)) protons in the universe (Technical endnote 1). The author explored the possibility tha ..."

that this number is fundamental to physics. Probabilities similar to the field of information theory developed by Claude Shannon [16] and others were used as tools to develop an information based approach to energy. Considering the probability of one neutron as 1/exp(180) a “top-down ” model lead to information

Top-Down Analysis for Bottom-Up Development

by Judith A. Stafford, John D. Mcgregor
"... Component-based software engineering (CBSE) is the construction of software systems from software components. Software components are independently deployable units of executable code that can be assembled into a system based on their externally visible properties, which are made available to system ..."

TOP-DOWN BEYOND THE STANDARD MODEL REVIEW

by Emilian Dudas, Centre De Physique Théorique, Ecole Polytechnique
"... The recent discovery of the Standard Model boson (SMS) and direct searches place new con-straints and a new perspective on New Physics models. I mostly review supersymmetric model building, with special emphasizes on predictions of flavor models on superpartner spectra and inverted hierarchy models, ..."

Manufacturing at nanoscale: Top-down, bottom-up and system

by Xiang Zhang, Cheng Sun, Nicholas Fang , 2003
"... The current nano-technology revolution is facing several major challenges: to manufacture nanodevices below 20 nm, to fabricate three-dimensional complex nano-structures, and to heterogeneously integrate multiple functionalities. To tackle these grand challenges, the Center for Scalable and Integrat ..."

Development of Top-Down Analysis of Distributed Assembly Tasks

by Anthony Cowley, M. Ani Hsieh
"... Distributed assembly tasks, in which large numbers of agents collaborate to produce composite objects out of component parts, require careful algorithm design to ensure behavior that scales well with the numbers of agents and parts. Yet al-gorithm evaluation, through which design is guided, is com-p ..."

Anonymization of Set-Valued Data via Top-Down, Local Generalization

by Yeye He, et al. , 2009
"... Set-valued data, in which a set of values are associated with an individual, is common in databases ranging from market basket data, to medical databases of patients ’ symptoms and behaviors, to query engine search logs. Anonymizing this data is important if we are to reconcile the conflicting deman ..."

, are not well-suited for set-valued data. In this paper we propose a top-down, partition-based approach to anonymizing set-valued data that scales linearly with the input size and scores well on an information-loss data quality metric. We further note that our technique can be applied to anonymize the infamous
