• Two-Sided Nearest Neighbors: An adaptive and minimax optimal procedure for matrix completion

  Tathagata Sadhukhan, Manit Paul, Raaz Dwivedi · 26 August 2026

  Nearest neighbor (NN) algorithms have been extensively used for missing data problems in recommender systems and sequential decision-making systems. Prior theoretical analysis has established favorable guarantees for NN when the underlying data is sufficiently smooth and the missingness probabilitie…

• Mixed-Timescale Differential Coding for Downlink Model Broadcast in Wireless Federated Learning

  Chung-Hsuan Hu, Zheng Chen, Erik G. Larsson · 16 July 2026

  In standard federated learning systems, the parameter server broadcasts the global model to the participating devices in every iteration. Motivated by the temporal correlation between consecutive global models, differential coding can be applied to global model dissemination to reduce the informatio…

• Convex Approximation of Two-Layer ReLU Networks for Hidden State Differential Privacy

  Rob Romijnders, Antti Koskela · 16 June 2026

  The hidden state threat model of differential privacy (DP) assumes that the adversary has access only to the final trained machine learning (ML) model, without seeing intermediate states during training. However, the current privacy analyses under this model are restricted to convex optimization pro…

• LinkAnchor: An Autonomous LLM-Based Agent for Issue-to-Commit Link Recovery

  Arshia Akhavan, Alireza Hosseinpour, Abbas Heydarnoori, Hamid Bagheri, Mehdi Keshani · 4 May 2026

  Issue-to-commit link recovery in software repositories is fundamental to software traceability and project management, yet it remains a challenging task. Prior studies show that only about 42.2% of issues on GitHub are correctly linked to their commits, highlighting the need for more effective solut…
