Numeric data such as statistics and from sensors are increasingly published on the Web and – if brought together for comparisons and calculations – can answer important questions in science, industry, and politics. For instance, natural scientists compare rainfall values from sensors with hydrological estimations documented in a semantic wiki; financial analysts evaluate companies based on comp...

Genetic programming is relatively poor at discovering useful numeric constants for the terminal nodes of its sexpression trees. In this paper we outline an adaptation to genetic programming, called numeric mutation. ~,Ve provide empirical evidence and analysis that demonstrate that numeric mutation makes a statistically significant increase in genetic programming’s performance for symbolic regr...

We propose a new chemical detection technique in which an analyte's vibrational frequencies are interrogated directly using an array of nanomechanical resonators. This "nanomechanical resonance spectroscopy" (NRS) could permit label-free chemical detection, combining the high sensitivity of nanomechanical approaches with the high selectivity of traditional spectroscopy. A computational proof of...

When people estimate a numeric value after judging whether it is larger or smaller than a high or low anchor value (comparative question), estimates are biased in the direction of the anchor. One explanation for this anchoring effect is that people selectively access knowledge consistent with the anchor value as part of a positive test strategy. Two studies (total N = 184) supported the alterna...

Many problems can be expressed in terms of a numeric constraint satisfaction problem over finite or continuous domains (numeric CSP). The purpose of this paper is to show that the consistency techniques that have been developed for CSPs can be adapted to numeric CSPs. Since the numeric domains are ordered the underlying idea is to handle domains only by their bounds. The semantics that have bee...
