论文摘要
本文通过开发计算机程序(称为Analogator)来探讨学习和类比制造的整合,该程序学会以身作则地进行类比。通过“看到”许多不同的类比问题以及可能的解决方案,类似物逐渐发展出一种新的类比的能力。也就是说,它学会了通过类比进行类比。这种方法与大多数现有的类比制作研究相反,在这种研究中通常假定模型中的类似机制的先验存在。本研究通过为经常性网络体系结构开发专门的关联培训程序扩展了标准的连接方法。该网络经过训练,将输入场景(或情况)分为适当的图形和地面组件。从特定的人物和地面上看到一个场景为以类似方式看到另一个场景提供了背景。训练后,该模型能够在新型情况之间进行新的类比。类似物与分类和识别的低级感知模型有很多共同点。因此,它是一个统一的框架,包括高级类似学习和低级感知。将这种方法比较并与其他类比制造的计算模型形成鲜明对比。检查了模型的培训和概括性能,并讨论了局限性。
This dissertation explores the integration of learning and analogy-making through the development of a computer program, called Analogator, that learns to make analogies by example. By "seeing" many different analogy problems, along with possible solutions, Analogator gradually develops an ability to make new analogies. That is, it learns to make analogies by analogy. This approach stands in contrast to most existing research on analogy-making, in which typically the a priori existence of analogical mechanisms within a model is assumed. The present research extends standard connectionist methodologies by developing a specialized associative training procedure for a recurrent network architecture. The network is trained to divide input scenes (or situations) into appropriate figure and ground components. Seeing one scene in terms of a particular figure and ground provides the context for seeing another in an analogous fashion. After training, the model is able to make new analogies between novel situations. Analogator has much in common with lower-level perceptual models of categorization and recognition; it thus serves as a unifying framework encompassing both high-level analogical learning and low-level perception. This approach is compared and contrasted with other computational models of analogy-making. The model's training and generalization performance is examined, and limitations are discussed.
