Salsa Fresca: Angular Embeddings and Pre-Training for ML Attacks on Learning With Errors

no code implementations2 Feb 2024 Samuel Stevens, Emily Wenger, Cathy Li, Niklas Nolte, Eshika Saxena, François Charton, Kristin Lauter

Our architecture improvements enable scaling to larger-dimension LWE problems: this work is the first instance of ML attacks recovering sparse binary secrets in dimension $n=1024$, the smallest dimension used in practice for homomorphic encryption applications of LWE where sparse binary secrets are proposed.

BioCLIP: A Vision Foundation Model for the Tree of Life

1 code implementation30 Nov 2023 Samuel Stevens, Jiaman Wu, Matthew J Thompson, Elizabeth G Campolongo, Chan Hee Song, David Edward Carlyn, Li Dong, Wasila M Dahdul, Charles Stewart, Tanya Berger-Wolf, Wei-Lun Chao, Yu Su

We then develop BioCLIP, a foundation model for the tree of life, leveraging the unique properties of biology captured by TreeOfLife-10M, namely the abundance and variety of images of plants, animals, and fungi, together with the availability of rich structured biological knowledge.

A Simple Interpretable Transformer for Fine-Grained Image Classification and Analysis

1 code implementation7 Nov 2023 Dipanjyoti Paul, Arpita Chowdhury, Xinqi Xiong, Feng-Ju Chang, David Carlyn, Samuel Stevens, Kaiya Provost, Anuj Karpatne, Bryan Carstens, Daniel Rubenstein, Charles Stewart, Tanya Berger-Wolf, Yu Su, Wei-Lun Chao

Unlike mainstream classifiers that wait until the last fully-connected layer to incorporate class information to make predictions, we investigate a proactive approach, asking each class to search for itself in an image.

arXivEdits: Understanding the Human Revision Process in Scientific Writing

no code implementations26 Oct 2022 Chao Jiang, Wei Xu, Samuel Stevens

We first introduce arXivEdits, a new annotated corpus of 751 full papers from arXiv with gold sentence alignment across their multiple versions of revision, as well as fine-grained span-level edits and their underlying intentions for 1, 000 sentence pairs.

An Investigation of Language Model Interpretability via Sentence Editing

2 code implementations EMNLP (BlackboxNLP) 2021 Samuel Stevens, Yu Su

Pre-trained language models (PLMs) like BERT are being used for almost all language-related tasks, but interpreting their behavior still remains a significant challenge and many important questions remain largely unanswered.
