Joint Feature and Differentiable -NN Graph Learning using Dirichlet Energy
Lei Xu, Lei Chen, Rong Wang +2
Feature selection (FS) plays an important role in machine learning, which extracts important features and accelerates the learning process. In this paper, we propose a deep FS meth…
How does Contrastive Learning Organize Images?
Yunzhe Zhang, Yao Lu, Qi Xuan
Contrastive learning, a dominant self-supervised technique, emphasizes similarity in representations between augmentations of the same input and dissimilarity for different ones. A…
HatCUP: Hybrid Analysis and Attention based Just-In-Time Comment Updating
Hongquan Zhu, Xincheng He, Lei Xu
When changing code, developers sometimes neglect updating the related comments, bringing inconsistent or outdated comments. These comments increase the cost of program understandin…
D^2ETR: Decoder-Only DETR with Computationally Efficient Cross-Scale Attention
Junyu Lin, Xiaofeng Mao, Yuefeng Chen +3
DETR is the first fully end-to-end detector that predicts a final set of predictions without post-processing. However, it suffers from problems such as low performance and slow con…
A Photonic-Circuits-Inspired Compact Network: Toward Real-Time Wireless Signal Classification at the Edge
Hsuan-Tung Peng, Joshua Lederman, Lei Xu +5
Machine learning (ML) methods are ubiquitous in wireless communication systems and have proven powerful for applications including radio-frequency (RF) fingerprinting, automatic mo…
Rewriting Meaningful Sentences via Conditional BERT Sampling and an application on fooling text classifiers
Lei Xu, Ivan Ramirez, Kalyan Veeramachaneni
Most adversarial attack methods that are designed to deceive a text classifier change the text classifier's prediction by modifying a few words or characters. Few try to attack cla…
Robust Invisible Video Watermarking with Attention
Kevin Alex Zhang, Lei Xu, Alfredo Cuesta-Infante +1
The goal of video watermarking is to embed a message within a video file in a way such that it minimally impacts the viewing experience but can be recovered even if the video is re…
MLFriend: Interactive Prediction Task Recommendation for Event-Driven Time-Series Data
Lei Xu, Shubhra Kanti Karmaker Santu, Kalyan Veeramachaneni
Most automation in machine learning focuses on model selection and hyper parameter tuning, and many overlook the challenge of automatically defining predictive tasks. We still heav…
Revisit Lmser and its further development based on convolutional layers
Wenjing Huang, Shikui Tu, Lei Xu
Proposed in 1991, Least Mean Square Error Reconstruction for self-organizing network, shortly Lmser, was a further development of the traditional auto-encoder (AE) by folding the a…
SteganoGAN: High Capacity Image Steganography with GANs
Kevin Alex Zhang, Alfredo Cuesta-Infante, Lei Xu +1
Image steganography is a procedure for hiding messages inside pictures. While other techniques such as cryptography aim to prevent adversaries from reading the secret message, steg…
TREVERSE: Trial-and-Error Lightweight Secure Reverse Authentication with Simulatable PUFs
Yansong Gao, Marten van Dijk, Lei Xu +3
A physical unclonable function (PUF) generates hardware intrinsic volatile secrets by exploiting uncontrollable manufacturing randomness. Although PUFs provide the potential for li…
Sketch-pix2seq: a Model to Generate Sketches of Multiple Categories
Yajing Chen, Shikui Tu, Yuqi Yi +1
Sketch is an important media for human to communicate ideas, which reflects the superiority of human intelligence. Studies on sketch can be roughly summarized into recognition and…
