Conformal Network Link Prediction with False Discovery Rate Control under Unstructured Missingness
Wenqin Du, Wanteng Ma, Dong Xia +2
We propose a new method for predicting multiple missing links in partially observed networks while controlling the false discovery rate (FDR), a largely unresolved challenge in net…
Connection Probabilities Estimation in Multi-layer Networks via Iterative Neighborhood Smoothing
Dingzi Guo, Diqing Li, Jingyi Wang +1
Understanding the structural mechanisms of multi-layer networks is essential for analyzing complex systems characterized by multiple interacting layers. This work studies the probl…
Rethinking Generative Recommender Tokenizer: Recsys-Native Encoding and Semantic Quantization Beyond LLMs
Yu Liang, Zhongjin Zhang, Yuxuan Zhu +10
Semantic ID (SID)-based recommendation is a promising paradigm for scaling sequential recommender systems, but existing methods largely follow a semantic-centric pipeline: item emb…
SGD with Dependent Data: Optimal Estimation, Regret, and Inference
Yinan Shen, Yichen Zhang, Wen-Xin Zhou
This work investigates the performance of the final iterate produced by stochastic gradient descent (SGD) under temporally dependent data. We consider two complementary sources of…
Online Quantile Regression
Yinan Shen, Dong Xia, Wen-Xin Zhou
This paper addresses the challenge of integrating sequentially arriving data within the quantile regression framework, where the number of features is allowed to grow with the numb…
