Resolution Limits for the Noisy Non-Adaptive 20 Questions Problem

2021 · IEEE Transactions on Information Theory

We establish fundamental limits on estimation accuracy for the noisy 20 questions problem with measurement-dependent noise and introduce optimal non-adaptive procedures that achieve these limits. The minimal achievable resolution is defined as the absolute difference …

Resolution Limits of Non-Adaptive 20 Questions Search for Multiple Targets

2021 · arXiv (Cornell University)

We study the problem of simultaneous search for multiple targets over a multidimensional unit cube and derive fundamental resolution limits of non-adaptive querying procedures using the 20 questions estimation framework. The performance criterion that we …

CoRe-KD: Contrastive Multi-Teacher and Retention-Aware Knowledge Distillation for Continual Multilingual Neural Machine Translation

2025 · Data Intelligence

A longstanding objective of multilingual neural machine translation (MNMT) is to expand models to acquire new knowledge from incremental translation tasks over time. Existing methods predominantly concentrate on mitigating catastrophic forgetting by compromising between original …
