Experimenting in Equilibrium

چکیده
Classical approaches to experimental design assume that intervening on one unit does not affect other units. There are many important settings, however, where this noninterference assumption hold, as when running experiments supply-side incentives a ride-sharing platform or subsidies in an energy marketplace. In paper, we introduce new approach large-scale stochastic systems with considerable cross-unit interference, under the interference is structured enough it can be captured via mean-field modeling. Our enables us accurately estimate effect of small changes system parameters by combining unobtrusive randomization lightweight modeling, all while remaining equilibrium. We then use these estimates optimize gradient descent. Concretely, focus problem seeks payments [Formula: see text] centralized marketplace different suppliers interact their effects overall supply-demand equilibrium, and show our large using vanishingly perturbations.

Experimenting with Clarification in Dialogue
A new technique for integrating experimental manipulations into text-based, synchronous dialogue is introduced. This method supports fine-grained, systematic transformation of conversational turns and the introduction of ‘artificial’ probe turns and turn sequences. It can be used to introduce manipulations that are sensitive to aspects of the local linguistic and conversational context for any ...
متن کاملExperimenting with eXtreme Design
Ontology Design Patterns (ODPs) support reusability and use of best practices in ontology engineering. Previous studies have shown that Content ODPs, in particular, have some measurable beneficial effects on the produced ontologies. However, another conclusion was that methodology and tool support was needed. Now such support exist, in the form of the XD methodology and the XD Tools. In this pa...

One application domain for Service Oriented Architectures (W3C Work. Group 2004) is ontology and metadata processing in the semantic web. Ontology-based approaches (Amann et al. 2002) pursue the interoperability among different sources of information by envisioning the development of software systems cooperation based on the sharing of semantics about data. Ontology Web Services are SOA impleme...
