Recommending on graphs: a comprehensive review from a data perspective
Lemei Zhang, Peng Liu, Jon Atle Gulla
Recent advances in graph-based learning approaches have demonstrated their effectiveness in modelling users' preferences and items' characteristics for Recommender Systems (RSS). M…
Quantifying syntax similarity with a polynomial representation of dependency trees
Pengyu Liu, Tinghao Feng, Rui Liu
We introduce a graph polynomial that distinguishes tree structures to represent dependency grammar and a measure based on the polynomial representation to quantify syntax similarit…
Remapped Cache Layout: Thwarting Cache-Based Side-Channel Attacks with a Hardware Defense
Wei Song, Rui Hou, Peng Liu +6
As cache-based side-channel attacks become serious security problems, various defenses have been proposed and deployed in both software and hardware. Consequently, cache-based side…
Nowhere to Hide: A Lightweight Unsupervised Detector against Adversarial Examples
Hui Liu, Bo Zhao, Kehuan Zhang +1
Although deep neural networks (DNNs) have shown impressive performance on many perceptual tasks, they are vulnerable to adversarial examples that are generated by adding slight but…
Towards a Unified Multi-Dimensional Evaluator for Text Generation
Ming Zhong, Yang Liu, Da Yin +6
Multi-dimensional evaluation is the dominant paradigm for human evaluation in Natural Language Generation (NLG), i.e., evaluating the generated text from multiple explainable dimen…
Dynamical descalarization in Einstein-Maxwell-scalar theory
Chao Niu, Wei Xiong, Peng Liu +2
For an asymptotically flat hairy black hole in the Einstein-Maxwell-scalar (EMS) theory, we study the possibility of shedding off its scalar hair via nonlinear scalar perturbation…
