Emergence of a High-Dimensional Abstraction Phase in Language Transformers

ICLR 2025poster

A language model (LM) is a mapping from a linguistic context to an output token. However, much remains to be known about this mapping, including how its geometric properties relate to its function. We take a high-level geometric approach to its analysis, observing, across five pre-trained transforme…

Bridging Information-Theoretic and Geometric Compression in Language Models

EMNLP 2023long main

For a language model (LM) to faithfully model human language, it must compress vast, potentially infinite information into relatively few dimensions. We propose analyzing compression in (pre-trained) LMs from two points of view: geometric and information-theoretic. We demonstrate that the two views…

Unnatural language processing: How do language models handle machine-generated prompts?

EMNLP 2023long findings

Language model prompt optimization research has shown that semantically and grammatically well-formed manually crafted prompts are routinely outperformed by automatically generated token sequences with no apparent meaning or syntactic structure, including sequences of vectors from a model's embeddin…

How Transferable Are Reasoning Patterns in VQA?

CVPR 2021poster

Since its inception, Visual Question Answering (VQA) is notoriously known as a task, where models are prone to exploit biases in datasets to find shortcuts instead of performing high-level reasoning. Classical methods address this by removing biases from training data, or adding branches to models t…

Roses Are Red, Violets Are Blue... but Should VQA Expect Them To?

CVPR 2021poster

Models for Visual Question Answering (VQA) are notorious for their tendency to rely on dataset biases, as the large and unbalanced diversity of questions and concepts involved and tends to prevent models from learning to ""reason"", leading them to perform ""educated guesses"" instead. In this paper…

Supervising the Transfer of Reasoning Patterns in VQA

NeurIPS 2021poster

Methods for Visual Question Anwering (VQA) are notorious for leveraging dataset biases rather than performing reasoning, hindering generalization. It has been recently shown that better reasoning patterns emerge in attention layers of a state-of-the-art VQA model when they are trained on perfect (or…
