MISFIT-V: Misaligned Image Synthesis and Fusion using Information from Thermal and Visual

1 code implementation22 Sep 2023 Aadhar Chauhan, Isaac Remy, Danny Broyles, Karen Leung

Detecting humans from airborne visual and thermal imagery is a fundamental challenge for Wilderness Search-and-Rescue (WiSAR) teams, who must perform this function accurately in the face of immense pressure.

WiSARD: A Labeled Visual and Thermal Image Dataset for Wilderness Search and Rescue

no code implementations8 Sep 2023 Daniel Broyles, Christopher R. Hayner, Karen Leung

Unfortunately, visual sensors alone do not address the need for robustness across all the possible terrains, weather, and lighting conditions that WiSAR operations can be conducted in.

HALO: Hazard-Aware Landing Optimization for Autonomous Systems

1 code implementation4 Apr 2023 Christopher R. Hayner, Samuel C. Buckner, Daniel Broyles, Evelyn Madewell, Karen Leung, Behcet Acikmese

With autonomous aerial vehicles enacting safety-critical missions, such as the Mars Science Laboratory Curiosity rover's landing on Mars, the tasks of automatically identifying and reasoning about potentially hazardous landing sites is paramount.

Towards Data-Driven Synthesis of Autonomous Vehicle Safety Concepts

no code implementations30 Jul 2021 Karen Leung, Andrea Bajcsy, Edward Schmerling, Marco Pavone

As safety-critical autonomous vehicles (AVs) will soon become pervasive in our society, a number of safety concepts for trusted AV deployment have recently been proposed throughout industry and academia.

Multimodal Deep Generative Models for Trajectory Prediction: A Conditional Variational Autoencoder Approach

no code implementations10 Aug 2020 Boris Ivanovic, Karen Leung, Edward Schmerling, Marco Pavone

Human behavior prediction models enable robots to anticipate how humans may react to their actions, and hence are instrumental to devising safe and proactive robot planning algorithms.

Backpropagation through Signal Temporal Logic Specifications: Infusing Logical Structure into Gradient-Based Methods

1 code implementation31 Jul 2020 Karen Leung, Nikos Aréchiga, Marco Pavone

This paper presents a technique, named STLCG, to compute the quantitative semantics of Signal Temporal Logic (STL) formulas using computation graphs.

Better AI through Logical Scaffolding

no code implementations12 Sep 2019 Nikos Arechiga, Jonathan DeCastro, Soonho Kong, Karen Leung

We describe the concept of logical scaffolds, which can be used to improve the quality of software that relies on AI components.

Generative Modeling of Multimodal Multi-Human Behavior

1 code implementation6 Mar 2018 Boris Ivanovic, Edward Schmerling, Karen Leung, Marco Pavone

This work presents a methodology for modeling and predicting human behavior in settings with N humans interacting in highly multimodal scenarios (i. e. where there are many possible highly-distinct futures).

Multimodal Probabilistic Model-Based Planning for Human-Robot Interaction

1 code implementation25 Oct 2017 Edward Schmerling, Karen Leung, Wolf Vollprecht, Marco Pavone

This paper presents a method for constructing human-robot interaction policies in settings where multimodality, i. e., the possibility of multiple highly distinct futures, plays a critical role in decision making.
