在本节中,我们将介绍在《Machine Learning on Graphs: A Model and Comprehensive Taxonomy》https://arxiv.org/abs/2005.03675中定义的分类法的简化版本。 在这种形式表示中,每个图、节点或边缘嵌入方法都可以由两个基本组件来描述,即编码器和解码器。编码器(encoder,ENC)将输入映射到嵌入空间,而解码器(decoder,DE...
Learning algorithms use training data that represents experience as input and create expertise as output. That output can be a computer program, a complex predictive model, or tuning of internal variables. The definition of performance depends on the specific algorithm or goal to be achieved; in ...

Knowledge Graphs Enhance ML From Sourcing to Training to Predictions AI and machine learning are playing an ever-increasing role in enterprises today. Machine learning is used in every industry: in healthcare to detect cancerous tumors, in supply chains to find factors that positively and negatively...
training. Learning on multimodal datasets is challenging because the inductive biases can vary by data modality and graphs might not be explicitly given in the input. To address these challenges, graph artificial intelligence methods combine different modalities while leveraging cross-modal dependencies ...
今天给大家讲一篇2021年1月发表在Machine Learning上的用大规模数据在分子生成的一篇文章,本文提出了利用自编码器生成具有期望性质的有效分子,是一项具有挑战性的任务。近年来,原子级自回归模型通常根据添加原子级节点和边的顺序动作构造图。作者提出了一种方法来自动从给定的分子图中发现这些常见的子结构。还提出了一种...
A method may include retrieving, over a network device, data from a data source, the data formatted according to a relational database schema; converting, using at least one processor, the data from the data source into a knowledge graph; training, using the at least one processor, a ...

问题通常可以被表述为回归任务,其中输入X必须被映射到输出Y。训练数据被生成或收集,然后由算法处理,这些算法试图接近未知的映射。这个架构包括四个主要部分,即训练数据(training data)、假设集(hypothesis set)、学习算法(learning algorithm)和最终假设(final hypothesis)[32]。
