Time, Self and Reified Artefacts

Reified Context Models

A classic tension exists between exact inference in a simple model and approximate inference in a complex model. The latter offers expressivity and thus accuracy, but the former provides coverage of the space, an important property for confidence estimation and learning with indirect supervision. In this work, we introduce a new approach, reified context models, to reconcile this tension. Speci...

Representing reified relations in Loom

This paper discusses the semantics and usage of rei cation as applied to relations and tuples. The rei cation of a tuple is a proposition object possessing a case role for each domain attribute in the tuple. The rei cation of a set of llers of a role is an object sometimes referred to as a \roleset". In the course of de ning rei cation mechanisms for the Loom knowledge representation system, we...

Artificial cells as reified quines

Cellular automata were initially conceived as a formal model to study self-replicating systems. Although reproduction by biological cells is characterized by exponential population increase, no population of self-replicating machines modeled as a cellular automaton has ever exhibited such rapid growth. We believe this is due to the inability of cellular automata to model bonded complexes of rei...

Reified Misconceptions 1 Running head: REIFIED MISCONCEPTIONS Missing Links: How Cladograms Reify Common Evolutionary Misconceptions

Cladograms are tree-like structures devised by evolutionary biologists for conveying patterns of shared ancestry among biological kinds. These representations have become highly popular in science textbooks and science museums, yet most non-biologists have difficulty reading them. Here, I discuss how those difficulties stem from common misconceptions about evolution— misconceptions reinforced n...
