Privately Fine-Tuning Large Language Models with Differential Privacy

no code implementations26 Oct 2022 Rouzbeh Behnia, Mohamamdreza Ebrahimi, Jason Pacheco, Balaji Padmanabhan

Differential privacy (DP) provides a rigorous framework that allows adding noise in the process of training or fine-tuning LLMs such that extracting the training data becomes infeasible (i. e., with a cryptographically small success probability).

Network-level Safety Metrics for Overall Traffic Safety Assessment: A Case Study

no code implementations27 Jan 2022 Xiwen Chen, Hao Wang, Abolfazl Razi, Brendan Russo, Jason Pacheco, John Roberts, Jeffrey Wishart, Larry Head, Alonso Granados Baca

To bridge these two perspectives, we define a new set of network-level safety metrics (NSM) to assess the overall safety profile of traffic flow by processing imagery taken by RSU cameras.

Lightweight Data Fusion with Conjugate Mappings

no code implementations20 Nov 2020 Christopher L. Dean, Stephen J. Lee, Jason Pacheco, John W. Fisher III

We present an approach to data fusion that combines the interpretability of structured probabilistic graphical models with the flexibility of neural networks.

A Robust Approach to Sequential Information Theoretic Planning

no code implementations ICML 2018 Sue Zheng, Jason Pacheco, John Fisher

In many sequential planning applications a natural approach to generating high quality plans is to maximize an information reward such as mutual information (MI).

Multiscale Semi-Markov Dynamics for Intracortical Brain-Computer Interfaces

no code implementations NeurIPS 2017 Daniel Milstein, Jason Pacheco, Leigh Hochberg, John D. Simeral, Beata Jarosiewicz, Erik Sudderth

We propose a dynamic Bayesian network that includes the on-screen goal position as part of its latent state, and thus allows the person’s intended angle of movement to be aggregated over a much longer history of neural activity.

Minimization of Continuous Bethe Approximations: A Positive Variation

no code implementations NeurIPS 2012 Jason Pacheco, Erik B. Sudderth

We develop convergent minimization algorithms for Bethe variational approximations which explicitly constrain marginal estimates to families of valid distributions.
