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 ...

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.

Adversarial Metric Learning [PDF]

open access: yesProceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence, 2018
In the past decades, intensive efforts have been put to design various loss functions and metric forms for metric learning problem. These improvements have shown promising results when the test data is similar to the training data. However, the trained models often fail to produce reliable distances on the ambiguous test pairs due to the different ...

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.

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.

Research on personnel re-recognition method in coal mine underground based on improved metric learning

open access: yesGong-kuang zidonghua, 2023
In the traditional personnel re-recognition method in coal mine underground based on metric learning, because metric learning ignores the absolute distance between positive and negative samples, the gradient of the loss function disappears or disperses ...

Multi-Sensors System and Deep Learning Models for Object Tracking

open access: yesSensors, 2023
Autonomous navigation relies on the crucial aspect of perceiving the environment to ensure the safe navigation of an autonomous platform, taking into consideration surrounding objects and their potential movements. Consequently, a fundamental requirement

A Multi-Layer Feature Fusion Method for Few-Shot Image Classification

open access: yesSensors, 2023
In image classification, few-shot learning deals with recognizing visual categories from a few tagged examples. The degree of expressiveness of the encoded features in this scenario is a crucial question that needs to be addressed in the models being ...
