中文简介: | 图上机器学习是一项重要而普遍的任务,其应用范围从药物设计到社交网络中的友谊推荐。该领域的主要挑战是找到一种表示或编码图结构的方法,以便机器学习模型能够轻松地利用它。然而,传统的机器学习方法依赖于用户定义的启发式方法来提取编码图形结构信息的特征。在这篇演讲中,我将讨论使用基于深度学习和非线性降维的技术,自动学习将图结构编码为低维嵌入的方法。我将提供一个概念性的回顾,在这方面的主要进展,在图上的表现学习,包括随机游走算法,和图形卷积网络。我们将讨论在网络规模的推荐系统,医疗保健和知识表示和推理的应用。 |
课程简介: | Machine learning on graphs is an important and ubiquitous task with applications ranging from drug design to friendship recommendation in social networks. The primary challenge in this domain is finding a way to represent, or encode, graph structure so that it can be easily exploited by machine learning models. However, traditionally machine learning approaches relied on user-defined heuristics to extract features encoding structural information about a graph. In this talk I will discuss methods that automatically learn to encode graph structure into low-dimensional embeddings, using techniques based on deep learning and nonlinear dimensionality reduction. I will provide a conceptual review of key advancements in this area of representation learning on graphs, including random-walk based algorithms, and graph convolutional networks. We will discuss applications to web-scale recommender systems, healthcare and knowledge representation and reasoning. |
