LLaVA-Gemma: Accelerating Multimodal Foundation Models with a Compact Language Model

no code implementations29 Mar 2024 Musashi Hinck, Matthew L. Olson, David Cobbley, Shao-Yen Tseng, Vasudev Lal

We train a suite of multimodal foundation models (MMFM) using the popular LLaVA framework with the recently released Gemma family of large language models (LLMs).

Transformer-Powered Surrogates Close the ICF Simulation-Experiment Gap with Extremely Limited Data

no code implementations6 Dec 2023 Matthew L. Olson, Shusen Liu, Jayaraman J. Thiagarajan, Bogdan Kustowski, Weng-Keen Wong, Rushil Anirudh

Recent advances in machine learning, specifically transformer architecture, have led to significant advancements in commercial domains.

Cross-GAN Auditing: Unsupervised Identification of Attribute Level Similarities and Differences between Pretrained Generative Models

1 code implementation CVPR 2023 Matthew L. Olson, Shusen Liu, Rushil Anirudh, Jayaraman J. Thiagarajan, Peer-Timo Bremer, Weng-Keen Wong

To this end, we introduce Cross-GAN Auditing (xGA) that, given an established "reference" GAN and a newly proposed "client" GAN, jointly identifies intelligible attributes that are either common across both GANs, novel to the client GAN, or missing from the client GAN.

GANterfactual-RL: Understanding Reinforcement Learning Agents' Strategies through Visual Counterfactual Explanations

1 code implementation24 Feb 2023 Tobias Huber, Maximilian Demmler, Silvan Mertes, Matthew L. Olson, Elisabeth André

However, research focusing on counterfactual explanations, specifically for RL agents with visual input, is scarce and does not go beyond identifying defective agents.

Deep Generative Multimedia Children's Literature

no code implementations27 Sep 2022 Matthew L. Olson

Artistic work leveraging Machine Learning techniques is an increasingly popular endeavour for those with a creative lean.

Contrastive Identification of Covariate Shift in Image Data

no code implementations18 Aug 2021 Matthew L. Olson, Thuy-Vy Nguyen, Gaurav Dixit, Neale Ratzlaff, Weng-Keen Wong, Minsuk Kahng

Identifying covariate shift is crucial for making machine learning systems robust in the real world and for detecting training data biases that are not reflected in test data.

Counterfactual State Explanations for Reinforcement Learning Agents via Generative Deep Learning

1 code implementation29 Jan 2021 Matthew L. Olson, Roli Khanna, Lawrence Neal, Fuxin Li, Weng-Keen Wong

Our second user study investigates if counterfactual state explanations can help non-expert participants identify a flawed agent; we compare against a baseline approach based on a nearest neighbor explanation which uses images from the actual game.

Counterfactual States for Atari Agents via Generative Deep Learning

no code implementations27 Sep 2019 Matthew L. Olson, Lawrence Neal, Fuxin Li, Weng-Keen Wong

In this work, we introduce the concept of a counterfactual state to help humans gain a better understanding of what would need to change (minimally) in an Atari game image for the agent to choose a different action.
