Understanding Memorisation in LLMs: Dynamics, Influencing Factors, and Implications

no code implementations27 Jul 2024 Till Speicher, Mohammad Aflah Khan, Qinyuan Wu, Vedant Nanda, Soumi Das, Bishwamittra Ghosh, Krishna P. Gummadi, Evimaria Terzi

Understanding whether and to what extent large language models (LLMs) have memorised training data has important implications for the reliability of their output and the privacy of their training data.

Towards Reliable Latent Knowledge Estimation in LLMs: Zero-Prompt Many-Shot Based Factual Knowledge Extraction

1 code implementation19 Apr 2024 Qinyuan Wu, Mohammad Aflah Khan, Soumi Das, Vedant Nanda, Bishwamittra Ghosh, Camila Kolling, Till Speicher, Laurent Bindschaedler, Krishna P. Gummadi, Evimaria Terzi

Our knowledge estimator is both conceptually simpler (i. e., doesn't depend on meta-linguistic judgments of LLMs) and easier to apply (i. e., is not LLM-specific), and we demonstrate that it can surface more of the latent knowledge embedded in LLMs.

Team Formation amidst Conflicts

1 code implementation29 Feb 2024 Iasonas Nikolaou, Evimaria Terzi

We test and deploy our algorithms on real-world datasets and we show that our algorithms find assignments that are better than those found by natural baselines.

Online Submodular Maximization via Online Convex Optimization

1 code implementation8 Sep 2023 Tareq Si Salem, Gözde Özcan, Iasonas Nikolaou, Evimaria Terzi, Stratis Ioannidis

We study monotone submodular maximization under general matroid constraints in the online setting.

Finding teams that balance expert load and task coverage

no code implementations3 Nov 2020 Sofia Maria Nikolakaki, Mingxiang Cai, Evimaria Terzi

The core idea in this line of work has been the strict requirement that the team of experts assigned to complete a given task should contain a superset of the skills required by the task.

Learn to Earn: Enabling Coordination within a Ride Hailing Fleet

no code implementations19 Jun 2020 Harshal A. Chaudhari, John W. Byers, Evimaria Terzi

In contrast, computer scientists primarily view it as a demand prediction problem with the goal of preemptively repositioning supply to such neighborhoods using black box coordinated multi agent deep reinforcement learning based approaches.
