The Determinants of Credit Spread Changes.
- Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

credit spread changes. Second, we consider a host of new explanatory variables that proxy for changes in liquidity and other macro-economic effects. Finally, we perform a regression analysis on simulated data to demonstrate that our empirical findings are not being driven by the econometric techniques
Scientific workflow management and the Kepler system
- CONCURR. COMPUT.: PRACT. EXP
, 2006
"... Many scientific disciplines are now data and information driven, and new scientific knowledge is often gained by scientists putting together data analysis and knowledge discovery “pipelines”. A related trend is that more and more scientific communities realize the benefits of sharing their data and ..."

Source vs data-driven approach for live P2P streaming
- in: Proceedings of the IEEE International Conference on Networks
, 2006
"... Live streaming applications are increasing on the Internet. These applications are delay sensitive and need group communication. Presently, protocols designed for this kind of communication do not rely on the classical client/server model used in the Internet but organize the receivers into an overl ..."

compare them by simulation to specify what is the most appropriate approach for these protocols. We implement a new simulator of p2p network and we choose two well-known protocols for simulations: a sourcedriven and a data-driven protocol. To our knowledge, our works are the first to compare with the same
An iterative approach to build relevant ontology-aware data-driven models
"... In many fields involving complex environments or living organisms, data-driven models are useful to make simulations in order to extrapolate costly experiments and to design decision-support tools. Learning methods can be used to build interpretable models from data. However, to be really useful, su ..."

Data-driven Modeling and Prediction of Acute Toxicity of Pesticide Residues

and risk assessment processes. Starting from a general problem description we address and introduce concepts of multileveled self-organization for highdimensional modeling, model validation, model combining, and decision support within the frame of a knowledge discovery from noisy data.
Research Article Undersampled MR Image Reconstruction with Data-Driven Tight Frame
"... which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Undersampled magnetic resonance image reconstruction employing sparsity regularization has fascinated many researchers in recent years under the support of compressed sensing t ..."

proposes a data-driven tight frame magnetic image reconstruction (DDTF-MRI) method. By taking advantage of the efficiency and effectiveness of data-driven tight frame, DDTF-MRI trains an adaptive tight frame to sparsify the to-be-reconstructed MR image. Furthermore, a two-level Bregman iteration algorithm
Analyzing Due Process in the Workplace
- ACM Transactions on Office Information Systems
, 1986
"... Every office is an open system, and the products of office work are the result of decentralized negotiations. Changing patterns of task organization and alliance inevitably give rise to inconsistent knowledge bases and procedures. This implies that there are no globally correct answers to problems a ..."

Modeling and Measuring Organization Capital
- Journal of Political Economy
, 2005
"... Manufacturing plants have a clear life cycle: they are born small, grow substantially with age, and eventually die. Economists have long thought that this life cycle is driven by organization capital, the ac-cumulation of plant-specific knowledge. The location of plants in the life cycle determines ..."
