Leveraging Large Language Models for Structure Learning in Prompted Weak Supervision

1 code implementation2 Feb 2024 Jinyan Su, Peilin Yu, Jieyu Zhang, Stephen H. Bach

We propose a Structure Refining Module, a simple yet effective first approach based on the similarities of the prompts by taking advantage of the intrinsic structure in the embedding space.

Follow-Up Differential Descriptions: Language Models Resolve Ambiguities for Image Classification

1 code implementation10 Nov 2023 Reza Esfandiarpoor, Stephen H. Bach

However, current zero-shot methods select a subset of attributes regardless of commonalities between the target classes, potentially providing no useful information that would have helped to distinguish between them.

AI safety training and red-teaming of large language models (LLMs) are measures to mitigate the generation of unsafe content.

Enhancing CLIP with CLIP: Exploring Pseudolabeling for Limited-Label Prompt Tuning

2 code implementations NeurIPS 2023 Cristina Menghini, Andrew Delworth, Stephen H. Bach

We find that (1) unexplored prompt tuning strategies that iteratively refine pseudolabels consistently improve CLIP accuracy, by 19. 5 points in semi-supervised learning, by 28. 4 points in transductive zero-shot learning, and by 15. 2 points in unsupervised learning, and (2) unlike conventional semi-supervised pseudolabeling, which exacerbates model biases toward classes with higher-quality pseudolabels, prompt tuning leads to a more equitable distribution of per-class accuracy.

An Adaptive Method for Weak Supervision with Drifting Data

no code implementations2 Jun 2023 Alessio Mazzetto, Reza Esfandiarpoor, Eli Upfal, Stephen H. Bach

In particular, at each step, our algorithm guarantees an estimation of the current accuracies of the weak supervision sources over a window of past observations that minimizes a trade-off between the error due to the variance of the estimation and the error due to the drift.

Does CLIP Bind Concepts? Probing Compositionality in Large Image Models

1 code implementation20 Dec 2022 Martha Lewis, Nihal V. Nayak, Peilin Yu, Qinan Yu, Jack Merullo, Stephen H. Bach, Ellie Pavlick

In this work, we focus on the ability of a large pretrained vision and language model (CLIP) to encode compositional concepts and to bind variables in a structure-sensitive way (e. g., differentiating ''cube behind sphere'' from ''sphere behind cube'').
