The Blind Leading the Blind: Mutual Refinement of Approximate Theories

We describe mutual theory refinement, a method for refining world models in a reactive system. The method detects failures, explains their causes, and repairs the approximate models which caused the failures. Our approach foeuses on using one approximate model to refine another. This paper appears in The Proceedings of the Eighth International Workshop on Machine Learning (held at Northwestern ...

The eyeball test: can the blind leading the blind see better than the statistician?

The Blind Leading the Blind: Network-Based Location Estimation Under Uncertainty

We propose a probabilistic method for inferring the geographical locations of linked objects, such as users in a social network. Unlike existing methods, our model does not assume that the exact locations of any subset of the linked objects, like neighbors in a social network, are known. The method efficiently leverages prior knowledge on the locations, resulting in high geolocation accuracies ...

The blind leading the blind: use and misuse of blinding in randomized controlled trials.

The use of blinding strengthens the credibility of randomized controlled trials (RCTs) by minimizing bias. However, there is confusion surrounding the definition of blinding as well as the terms single, double, and triple blind. It has been suggested that these terms should be discontinued due to their broad misinterpretation. We recommend that, instead of abandoning the use of these terms, exp...

The Blind Leading the Blind: Toward Collaborative Online Route Information Management by Individuals with Visual Impairments

The long-term objective of our project is to discover the fundamental principles underlying the collaborative production, sharing, and management of route information by travelers with visual impairments. The specific research hypothesis is two-fold: 1) people with varied levels of vision loss and orientation and mobility (O&M) skills will be able to form online social networks that collaborati...
