Entities in ContextPartner: Meta Platforms Inc.Participants: Saeed Goodarzi, Nikhil Kagita, Dennis MinnDescription: We revisited the generalization effectiveness of LLMs by focusing on named entities. Named entities are ubiquitous in current Natural Language Understanding benchmarks, yet they have been largely ignored in order to examine the impact on models' reasoning capabilities. We subjected models to the same evaluation data while modifying them to iterate through a large array of named entities from diverse demographics.

Simple Strategies to Select Layers for Fine-Tuning Language Encoders Partner: Microsoft, MAIDAP Participants: Gayatri Belapurkar, Saloni Chalkapurkar, Abhilasha Lodha, Yuanming Tao Description: We proposed two-layer selection methods for fine-tuning language encoders that can comprehensively make the transfer learning process for common NLP tasks such as GLUE and SuperGLUE more resource efficient.

Editing Transformer Models with Common Sense Knowledge (EMNLP Conference, Dec. 2023)Partner: Allen Institute for AIParticipants: Anshita Gupta, Debanjan Mondal, Akshay Krishna SheshadriDescription: Memory editing for updating encyclopedic knowledge in transformers has received increasing attention, but it is unclear if these methods can be adapted for nuanced common sense knowledge. In this research, we proposed an adaptation of MEMIT to edit common sense mistakes in GPT-2 Large and XL. We extend editing to various token locations and employ a robust layer selection strategy. Our results suggest a promising path for improving GPT by incorporating context-specific user feedback about common sense through direct model editing as well as fixing and customizing model behaviors using human-in-the-loop-systems.
