Neural Analogical Matching
Analogy is core to human cognition. It allows us to solve problems based on
prior experience, it governs the way we conceptualize new information, and it
even influences our visual perception. The importance of analogy to humans has
made it an active area of research in the broader field of artificial
intelligence, resulting in data-efficient models that learn and reason in
human-like ways. While cognitive perspectives of analogy and deep learning have
generally been studied independently of one another, the integration of the two
lines of research is a promising step towards more robust and efficient
learning techniques. As part of a growing body of research on such an
integration, we introduce the Analogical Matching Network: a neural
architecture that learns to produce analogies between structured, symbolic
representations that are largely consistent with the principles of
Structure-Mapping Theory.Comment: AAAI versio
Accelerating Innovation Through Analogy Mining
The availability of large idea repositories (e.g., the U.S. patent database)
could significantly accelerate innovation and discovery by providing people
with inspiration from solutions to analogous problems. However, finding useful
analogies in these large, messy, real-world repositories remains a persistent
challenge for either human or automated methods. Previous approaches include
costly hand-created databases that have high relational structure (e.g.,
predicate calculus representations) but are very sparse. Simpler
machine-learning/information-retrieval similarity metrics can scale to large,
natural-language datasets, but struggle to account for structural similarity,
which is central to analogy. In this paper we explore the viability and value
of learning simpler structural representations, specifically, "problem
schemas", which specify the purpose of a product and the mechanisms by which it
achieves that purpose. Our approach combines crowdsourcing and recurrent neural
networks to extract purpose and mechanism vector representations from product
descriptions. We demonstrate that these learned vectors allow us to find
analogies with higher precision and recall than traditional
information-retrieval methods. In an ideation experiment, analogies retrieved
by our models significantly increased people's likelihood of generating
creative ideas compared to analogies retrieved by traditional methods. Our
results suggest a promising approach to enabling computational analogy at scale
is to learn and leverage weaker structural representations.Comment: KDD 201
Second order isomorphism: A reinterpretation and its implications in brain and cognitive sciences
Shepard and Chipman's second order isomorphism describes how
the brain may represent the relations in the world.
However, a common interpretation of the theory can cause difficulties.
The problem originates from the static nature
of representations. In an alternative interpretation, I propose that
we assign an active role to the internal representations and
relations. It turns out that a collection of such active units can
perform analogical tasks. The new interpretation is supported
by the existence of neural circuits that may be implementing such a function.
Within this framework, perception, cognition, and motor function
can be understood under a unifying principle of analogy
Analogy Mining for Specific Design Needs
Finding analogical inspirations in distant domains is a powerful way of
solving problems. However, as the number of inspirations that could be matched
and the dimensions on which that matching could occur grow, it becomes
challenging for designers to find inspirations relevant to their needs.
Furthermore, designers are often interested in exploring specific aspects of a
product-- for example, one designer might be interested in improving the
brewing capability of an outdoor coffee maker, while another might wish to
optimize for portability. In this paper we introduce a novel system for
targeting analogical search for specific needs. Specifically, we contribute a
novel analogical search engine for expressing and abstracting specific design
needs that returns more distant yet relevant inspirations than alternate
approaches
