Structured Relation Discovery using Generative Models
We explore unsupervised approaches to relation extraction between two named entities; for instance, the semantic bornIn relation between a person and location entity. Concretely, we propose a series of generative probabilistic models, broadly similar to topic models, each which generates a corpus of observed triples of entity mention pairs and the surface syntactic dependency path between them....
متن کاملComparative Study on Generative Adversarial Networks
In recent years, there have been tremendous advancements in the field of machine learning. These advancements have been made through both academic as well as industrial research. Lately, a fair amount of research has been dedicated to the usage of generative models in the field of computer vision and image classification. These generative models have been popularized through a new framework cal...
متن کاملGenerative Inferences Based on a Discriminative Bayesian Model of Relation Learning
Bayesian Analogy with Relational Transformations (BART) is a discriminative model that can learn comparative relations from non-relational inputs (Lu, Chen & Holyoak, 2012). Here we show that BART can be extended to solve inference problems that require generation (rather than classification) of relation instances. BART can use its generative capacity to perform hypothetical reasoning, enabling...
متن کاملGenerative model for feedback networks.
We propose a model for network formation and study some of its statistical properties. The motivation for the model comes from the growth of several kinds of real networks (i.e., kinship and trading networks, networks of corporate alliances, networks of autocatalytic chemical reactions). These networks grow either by establishing closer connections by adding links in the existing network or by ...
متن کاملA Generative Model of Phonotactics
We present a probabilistic model of phonotactics, the set of well-formed phoneme sequences in a language. Unlike most computational models of phonotactics (Hayes and Wilson, 2008; Goldsmith and Riggle, 2012), we take a fully generative approach, modeling a process where forms are built up out of subparts by phonologically-informed structure building operations. We learn an inventory of subparts...
