Features that Make a Difference: Leveraging Gradients for Improved Dictionary Learning

NAACL 2025findings

Sparse Autoencoders (SAEs) are a promising approach for extracting neural network representations by learning a sparse and overcomplete decomposition of the network’s internal activations. However, SAEs are traditionally trained considering only activation values and not the effect those activations…

An Information-theoretic Approach to Prompt Engineering Without Ground Truth Labels

ACL 2022long

Pre-trained language models derive substantial linguistic and factual knowledge from the massive corpora on which they are trained, and prompt engineering seeks to align these models to specific tasks. Unfortunately, existing prompt engineering methods require significant amounts of labeled data, ac…

Prompt Compression and Contrastive Conditioning for Controllability and Toxicity Reduction in Language Models

EMNLP 2022finding

We explore the idea of compressing the prompts used to condition language models, and show that compressed prompts can retain a substantive amount of information about the original prompt. For severely compressed prompts, while fine-grained information is lost, abstract information and general senti…

Leveraging the Inductive Bias of Large Language Models for Abstract Textual Reasoning

NeurIPS 2021poster

Large natural language models (LMs) (such as GPT-3 or T5) demonstrate impressive abilities across a range of general NLP tasks. Here, we show that the knowledge embedded in such models provides a useful inductive bias, not just on traditional NLP tasks, but also in the nontraditional task of trainin…

Deep visual gravity vector detection for unmanned aircraft attitude estimation

IROS 2017poster

This paper demonstrates a feasible method for using a deep neural network as a sensor to estimate the attitude of a flying vehicle using only flight video. A dataset of still images and associated gravity vectors was collected and used to perform supervised learning. The network builds on a previous…

Harvesting Common-sense Navigational Knowledge for Robotics from Uncurated Text Corpora

CoRL 2017

As robotic systems are deployed into everyday situations, the need for abstract reasoning becomes more pronounced. The ideal robotic assistant should be able to understand verbal commands and work independently to fulfill human-prescribed goals, even if instructions are ambiguous or circumstances ch
