Applications of Royen's Gaussian Correlation Inequality in high-dimensional testing
Jiashun Jin, Zheng Tracy Ke, Jingming Wang
Royen's Gaussian Correlation Inequality (GCI) is a fundamental result in statistics and probability, but unfortunately, at least by now, the result is not very well known in the st…
Fitting networks with a cancellation trick
Jiashun Jin, Jingming Wang
The degree-corrected block model (DCBM), latent space model (LSM), and -model are all popular network models. We combine their modeling ideas and propose the logit-DCBM as a new…
Network Goodness-of-Fit for the block-model family
Jiashun Jin, Zheng Tracy Ke, Jiajun Tang +1
The block-model family has four popular network models (SBM, DCBM, MMSBM, and DCMM). A fundamental problem is, how well each of these models fits with real networks. We propose GoF…
A Comparison of DeepSeek and Other LLMs
Tianchen Gao, Jiashun Jin, Zheng Tracy Ke +1
Recently, DeepSeek has been the focus of attention in and beyond the AI community. An interesting problem is how DeepSeek compares to other large language models (LLMs). There are…
Optimal Network Pairwise Comparison
Jiashun Jin, Zheng Tracy Ke, Shengming Luo +1
We are interested in the problem of two-sample network hypothesis testing: given two networks with the same set of nodes, we wish to test whether the underlying Bernoulli probabili…
Improved Algorithm and Bounds for Successive Projection
Jiashun Jin, Zheng Tracy Ke, Gabriel Moryoussef +2
Given a -vertex simplex in a -dimensional space, suppose we measure points on the simplex with noise (hence, some of the observed points fall outside the simplex). Vertex…
Recent Advances in Text Analysis
Zheng Tracy Ke, Pengsheng Ji, Jiashun Jin +1
Text analysis is an interesting research area in data science and has various applications, such as in artificial intelligence, biomedical research, and engineering. We review popu…
