Metric Learning for Structured Data

open access: yes, 2019
Distance measures form a backbone of machine learning and information retrieval in many application fields such as computer vision, natural language processing, and biology. However, general-purpose distances may fail to capture semantic particularities of a domain, leading to wrong inferences downstream. Motivated by such failures, the field of metric

Fault Diagnosis of Rolling Bearing Based on Modified Deep Metric Learning Method

open access: yesShock and Vibration, 2021
A novel fault diagnosis method of rolling bearing based on deep metric learning and Yu norm is proposed in this paper, which is called a deep metric learning method based on Yu norm (DMN-Yu).

Learning Neighborhoods for Metric Learning [PDF]

open access: yes, 2012
Metric learning methods have been shown to perform well on different learning tasks. Many of them rely on target neighborhood relationships that are computed in the original feature space and remain fixed throughout learning. As a result, the learned metric reflects the original neighborhood relations.

Metrics and Continuity in Reinforcement Learning

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
In most practical applications of reinforcement learning, it is untenable to maintain direct estimates for individual states; in continuous-state systems, it is impossible. Instead, researchers often leverage {\em state similarity} (whether explicitly or implicitly) to build models that can generalize well from a limited set of samples.

Pacing Electrocardiogram Detection With Memory-Based Autoencoder and Metric Learning

open access: yesFrontiers in Physiology, 2021
Remote ECG diagnosis has been widely used in the clinical ECG workflow. Especially for patients with pacemaker, in the limited information of patient's medical history, doctors need to determine whether the patient is wearing a pacemaker and also ...

Ground Metric Learning on Graphs [PDF]

open access: yesJournal of Mathematical Imaging and Vision, 2020
Optimal transport (OT) distances between probability distributions are parameterized by the ground metric they use between observations. Their relevance for real-life applications strongly hinges on whether that ground metric parameter is suitably chosen.

A Few-Shot Learning Method Using Feature Reparameterization and Dual-Distance Metric Learning for Object Re-Identification

open access: yesIEEE Access, 2021
Many object re-identification (Re-ID) methods that depend on large-scale training datasets have been proposed in recent years. However, the performance of these methods degrades dramatically when insufficient training data are available.
