Saddle solutions for the fractional Choquard equation [article]

Yin-Xin Cui, Jiankang Xia
2021 arXiv   pre-print
We study the saddle solutions for the fractional Choquard equation (-Δ)^su+ u=(K_α∗|u|^p)|u|^p-2u, x∈ℝ^N where s∈(0,1), N≥ 3 and K_α is the Riesz potential with order α∈ (0,N). For every Coxeter group G with rank 1≤ k≤ N and p∈[2,N+α/N-2s), we construct a G-saddle solution with prescribed symmetric nodal configurations. This is a counterpart for the fractional Choquard equation of saddle solutions to the Choquard equation and further completes the existence of non-radial sign-changing solutions for this doubly nonlocal equation.

Learning to Evaluate Image Captioning [article]

Yin Cui, Guandao Yang, Andreas Veit, Xun Huang, Serge Belongie
2018 arXiv   pre-print
Evaluation metrics for image captioning face two challenges. Firstly, commonly used metrics such as CIDEr, METEOR, ROUGE and BLEU often do not correlate well with human judgments. Secondly, each metric has well known blind spots to pathological caption constructions, and rule-based metrics lack provisions to repair such blind spots once identified. For example, the newly proposed SPICE correlates well with human judgments, but fails to capture the syntactic structure of a sentence. To address

In addition, we further propose a data augmentation scheme to explicitly incorporate pathological transformations as negative examples during training. The proposed metric is evaluated with three kinds of robustness tests and its correlation with human judgments. Extensive experiments show that the proposed data augmentation scheme not only makes our metric more robust toward several pathological transformations, but also improves its correlation with human judgments. Our metric outperforms other metrics on both caption level human correlation in Flickr 8k and system level human correlation in COCO. The proposed approach could be served as a learning based evaluation metric that is complementary to existing rule-based metrics.

Challenging the Long Tail Recommendation [article]

Hongzhi Yin, Bin Cui, Jing Li, Junjie Yao, Chen Chen
2012 arXiv   pre-print
The success of "infinite-inventory" retailers such as and Netflix has been largely attributed to a "long tail" phenomenon. Although the majority of their inventory is not in high demand, these niche products, unavailable at limited-inventory competitors, generate a significant fraction of total revenue in aggregate. In addition, tail product availability can boost head sales by offering consumers the convenience of "one-stop shopping" for both their mainstream and niche tastes.
more » ... r, most of existing recommender systems, especially collaborative filter based methods, can not recommend tail products due to the data sparsity issue. It has been widely acknowledged that to recommend popular products is easier yet more trivial while to recommend long tail products adds more novelty yet it is also a more challenging task. In this paper, we propose a novel suite of graph-based algorithms for the long tail recommendation. We first represent user-item information with undirected edge-weighted graph and investigate the theoretical foundation of applying Hitting Time algorithm for long tail item recommendation. To improve recommendation diversity and accuracy, we extend Hitting Time and propose efficient Absorbing Time algorithm to help users find their favorite long tail items. Finally, we refine the Absorbing Time algorithm and propose two entropy-biased Absorbing Cost algorithms to distinguish the variation on different user-item rating pairs, which further enhances the effectiveness of long tail recommendation. Empirical experiments on two real life datasets show that our proposed algorithms are effective to recommend long tail items and outperform state-of-the-art recommendation techniques.

Delay-Throughput Tradeoff for Supportive Two-Tier Networks [article]

Long Gao, Rui Zhang, Changchuan Yin, Shuguang Cui
2008 arXiv   pre-print
Consider a static wireless network that has two tiers with different priorities: a primary tier vs. a secondary tier. The primary tier consists of randomly distributed legacy nodes of density n, which have an absolute priority to access the spectrum. The secondary tier consists of randomly distributed cognitive nodes of density m=n^β with β≥ 2, which can only access the spectrum opportunistically to limit the interference to the primary tier. By allowing the secondary tier to route the packets

Revisiting 3D ResNets for Video Recognition [article]

Xianzhi Du, Yeqing Li, Yin Cui, Rui Qian, Jing Li, Irwan Bello
2021 arXiv   pre-print
A recent work from Bello shows that training and scaling strategies may be more significant than model architectures for visual recognition. This short note studies effective training and scaling strategies for video recognition models. We propose a simple scaling strategy for 3D ResNets, in combination with improved training strategies and minor architectural changes. The resulting models, termed 3D ResNet-RS, attain competitive performance of 81.0 on Kinetics-400 and 83.8 on Kinetics-600

Gels of Amyloid Fibers

Ruizhi Wang, Xiaojing Yang, Lingwen Cui, Hang Yin, Shaohua Xu
2019 Biomolecules  
Protein self-assembly and formation of amyloid fibers is an early event of numerous human diseases. Continuous aggregation of amyloid fibers in vitro produces biogels, which led us to suspect that amyloid plaques and neurofibrillary tangles in Alzheimer's disease are of biogels in nature. We applied atomic force microscopy, size exclusion chromatography, and differential scanning calorimetry to elucidate the gel's structure, kinetics of gel formation, and melting point. We found that (1)

The potential role of the gels formed by amyloid fibers in amyloidosis, particularly in Alzheimer's disease was thoroughly discussed, as gels with increased viscosity, are known to restrict bulk flow and then circulation of ions and molecules.
