Counting Cycles with AI: Counting Cycles with AI: Computationally Efficient Equivalent Forms with Applications
Jiashun Jin, Tracy Ke, Zheng Tracy Ke +2
Cycle count statistics are fundamental tools in statistics and engineering, with applications in motif counting, channel coding, and statistical inference of network and matrix dat…
Homogeneity in Regression
Tracy Ke, Jianqing Fan, Yichao Wu
This paper explores the homogeneity of coefficients in high-dimensional regression, which extends the sparsity concept and is more general and suitable for many applications. Homog…
Semi-supervised Community Detection via Structural Similarity Metrics
Yicong Jiang, Tracy Ke
Motivated by social network analysis and network-based recommendation systems, we study a semi-supervised community detection problem in which the objective is to estimate the comm…
Rare and Weak effects in Large-Scale Inference: methods and phase diagrams
Jiashun Jin, Tracy Ke
Often when we deal with `Big Data', the true effects we are interested in are Rare and Weak (RW). Researchers measure a large number of features, hoping to find perhaps only a smal…
Recite, Reconstruct, Recollect: Memorization in LMs as a Multifaceted Phenomenon
USVSN Sai Prashanth, Alvin Deng, Kyle O'Brien +9
Memorization in language models is typically treated as a homogenous phenomenon, neglecting the specifics of the memorized data. We instead model memorization as the effect of a se…
