1 Introduction 我们知道,CNNs、RNNs以及 autoencoders 等深度学习方法,可以取代手工的特征提取,有效地捕获欧氏数据的隐含特征。但现实生活中,数据更普遍的形式是可以被构建为图的非欧数据。例如,化学分子结构、知识图谱、电子商务等。 由于图可能是不规则的,节点大小、邻居数量不同,从而传统深度学习难以应用于图域。
Section 10.2 provides an introduction to autoencoders and their application in representation learning tasks. Section 10.3 presents the seminal approaches that introduced deep learning, and particularly deep Convolutional Neural Networks (CNN), to the retrieval domain. Section 10.4 presents model retraining...
SpareAutoencodersare a variation of autoencoders that try to keep as many neurons as possible, inactive, that is, close to 0. They also do not have a bottleneck like most autoencoders, in fact, often they have more neurons in the middle of the network than in the input layer, but ...
An autoencoder is a neural network trained to efficiently compress input data down to essential features and reconstruct it from the compressed representation.
Anomaly detection Autoencoder Neural network ACSS Financial market infrastructure Introduction Financial market infrastructures (FMIs) play a crucial role in our economy. They facilitate the clearing and settlement of financial obligations between financial institutions and their clients. An FMI that does not...
This included a detailed analysis of the different methods based on this measuring principle, before concluding with an introduction to new methods and existing tendencies. Analysis carried out in the same year looked into insufficiencies affecting single-flank rolling tests, and proposed corrective ...
