Spiking Wavelet Transformer

no code implementations17 Mar 2024 Yuetong Fang, Ziqing Wang, Lingfeng Zhang, Jiahang Cao, Honglei Chen, Renjing Xu

Spiking neural networks (SNNs) offer an energy-efficient alternative to conventional deep learning by mimicking the event-driven processing of the brain.

A Novel Center-based Deep Contrastive Metric Learning Method for the Detection of Polymicrogyria in Pediatric Brain MRI

1 code implementation22 Nov 2022 Lingfeng Zhang, Nishard Abdeen, Jochen Lang

We propose an anomaly detection method based on a novel center-based deep contrastive metric learning loss function (cDCM) which enables the automatic detection of cases of potential PMG.

Fully Associative Patch-based 1-to-N Matcher for Face Recognition

no code implementations15 May 2018 Lingfeng Zhang, Ioannis A. Kakadiaris

A Fully Associative Patch-based Signature Matcher (FAPSM) is proposed so that the local matching identity of each patch contributes to the global matching identities of all the patches.

A Hierarchical Matcher using Local Classifier Chains

no code implementations7 May 2018 Lingfeng Zhang, Ioannis A. Kakadiaris

This paper focuses on improving the performance of current convolutional neural networks in visual recognition without changing the network architecture.

Patch-based Face Recognition using a Hierarchical Multi-label Matcher

no code implementations3 Apr 2018 Lingfeng Zhang, Pengfei Dou, Ioannis A. Kakadiaris

Three ways are introduced to learn the global matching: majority voting, l1-regularized weighting, and decision rule.

A Face Recognition Signature Combining Patch-based Features with Soft Facial Attributes

no code implementations25 Mar 2018 Lingfeng Zhang, Pengfei Dou, Ioannis A. Kakadiaris

This paper focuses on improving face recognition performance with a new signature combining implicit facial features with explicit soft facial attributes.

Unsupervised Cross-Domain Recognition by Identifying Compact Joint Subspaces

no code implementations5 Sep 2015 Yuewei Lin, Jing Chen, Yu Cao, Youjie Zhou, Lingfeng Zhang, Yuan Yan Tang, Song Wang

By adopting a natural and widely used assumption -- "the data samples from the same class should lay on a low-dimensional subspace, even if they come from different domains", the proposed method circumvents the limitation of the global domain shift, and solves the cross-domain recognition by finding the compact joint subspaces of source and target domain.
