The Earth is a big place: its radius is about 6400 km. In comparison, the deepest boreholes drilled are about 10 km deep. We thus have little opportunity to take direct measurements or samples inside the Earth: it is mostly inaccessible. And even for the upper 10 km that we can sample, the cost of drilling deep boreholes is very high. This means that inferences about the Earth’s interior are la...

In practical applications of optimization it is common to have several conflicting objective functions to optimize. Frequently, these functions are subject to noise or can be of black-box type, preventing the use of derivative-based techniques. We propose a novel multiobjective derivative-free methodology, calling it direct multisearch (DMS), which does not aggregate any of the objective functi...

Knowing the provenance of a data item helps in ascertaining its trustworthiness. Various approaches have been proposed to track or infer data provenance. However, these approaches either treat an executing program as a black-box, limiting the fidelity of the captured provenance, or require developers to modify the program to make it provenance-aware. In this paper, we introduce DataTracker, a n...

High-dimensional gray-box identi cation is a fairly unexplored part of system identi cation. Nevertheless, system identi cation problems tend to be more high-dimensional nowadays. In this paper we deal with high-dimensional regression with regressors constrained to some manifold. A recent technique in this class is weight determination by manifold regularization (WDMR). WDMR, however, is a blac...

This paper describes two new features of the BRIDJE system for cross-language information access. The first feature is the partial disambiguation function of the Bi-directional Retriever, which can be used for search request translation in cross-language IR. Its advantage over a “black-box” machine translation approach is consistent across five test collections and across two language permutati...

The internal (or residual) stress is among the key notions to describe the state of the systems far from equilibrium. Such stress is invisible on the macroscopic scale where the system is regarded as a black-box. Yet nonequilibrium macroscopic operations allow to create and observe the internal stress. We present in this lecture some examples of the internal stress and its operations. We descri...

Due to increasing demand for simulation and modeling, efforts are needed to build up more powerful simulation and modeling methodologies that can help to facilitate learning complex dynamic systems. By learning we mean the acquisition of knowledge, skills and experience for better and faster learning of the various types of complex dynamic systems. System dynamics is one of the successful well ...

ACM 978-1-4503-5621-3/18/04. https://doi.org/10.1145/3170427.3188506 Abstract Sequence recommender systems assist people in making decisions, such as which product to purchase and what places to visit on vacation. Despite their ubiquity, most sequence recommender systems are black boxes an...

We show the existence of concurrent non-malleable commitments based on the existence of one-way functions. Our proof of security only requires the use of black-box techniques, and additionally provides an arguably simplified proof of the existence of even stand-alone secure non-malleable commitments.

We investigate here antecedents and consequences of supplier integration (black-box and gray-box) in product development activities. Antecedents include embeddedness with suppliers, supply base rationalization, and supplier selection based on product development capabilities. Product innovation and quality are modeled as returns of supplier integration in product development. We also assess the...
