Getting symbols out of a neural architecture

Traditional connectionist networks are sharply limited as general accounts of human perception and cognition because they are unable to represent relational ideas such as loves (John, Mary) or bigger-than (Volkswagen, breadbox) in a way that allows them to be manipulated as explicitly relational structures. This paper reviews and critiques the four major responses to this problem in the modelin...

Disseminating healthcare information: getting the message across.

Introduction It has been shown that there are often significant delays in incorporating clinical recommendations into routine practice. The biomedical knowledge base is expected to have doubled in size within the next 20 years; however, there is already evidence that even the existing volume of scientific information is unmanageable to those who use it (box 1). Its sources are diVuse and disorg...

Getting More Information into File Names

Hierarchical naming, while deeply embedded in our conception of file systems, is a rather weak tool for storing information about files and their relationships. A consequence is that users of today’s file systems frequently have trouble locating files. We describe a system in which a standard directory tree is extended by allowing names to contain auxiliary components representing descriptive a...

Getting the Measure of Positional Information

Understanding the mechanisms that underlie pattern formation is one of the major challenges of developmental biology. The complexity and beauty of the patterns on butterfly wings, fish scales, or bird feathers are not only remarkable products of developmental processes but puzzles that tease our intellects. If we are to understand these beautiful products of cellular activity, we need to first ...
