论文摘要
当前的大多数推理技术都依赖于观测值的概率图形模型的贝叶斯推论,并对观测值进行预测和分类。但是,关于观察结果与建立观测集或观察的生成环境之间关系之间关系的挖掘的文献很少。此外,对带有观测输入的机器的事件理解需要了解观察结果之间的关系。因此,至关重要的是建立模型并开发有效的数据结构,以积累和组织观测之间的关系。给定PGM模型,本文试图将状态的排列拟合到一系列观察令牌(旅行摄影师问题)中。我们已经设计了一种机器学习启发的体系结构,用于随机近似状态置换,从而促进对排列的启发式搜索并行化。结果,我们的算法可以以最小的错误解决旅行摄影师问题。此外,我们证明,通过模拟机器学习组件,例如归一化,辍学和lambda层,我们可以设计一个解决TPP的体系结构,这是一个置换的NP-HARD问题。除TPP外,我们还可以为旅行推销员问题(TSP)提供具有类似想法的旅行推销员问题(TSP)。
Most of the current inference techniques rely upon Bayesian inference on Probabilistic Graphical Models of observations and do predictions and classification on observations. However, there is very little literature on the mining of relationships between observations and building models of the relationship between sets of observations or the generating context of the observations. Moreover, event understanding of machines with observation inputs needs to understand the relationship between observations. Thus there is a crucial need to build models and develop effective data structures to accumulate and organize relationships between observations. Given a PGM model, this paper attempts to fit a permutation of states to a sequence of observation tokens (The Travelling Photographer Problem). We have devised a machine learning inspired architecture for randomized approximation of state permutation, facilitating parallelization of heuristic search of permutations. As a result, our algorithm can solve The Travelling Photographer Problem with minimal error. Furthermore, we demonstrate that by mimicking machine learning components such as normalization, dropout, and lambda layer with a randomized algorithm, we can devise an architecture that solves TPP, a permutation NP-Hard problem. Other than TPP, we can also provide a 2-Local improvement heuristic for the Travelling Salesman Problem (TSP) with similar ideas.
