Why Don't You Clean Your Glasses? Perception Attacks with Dynamic Optical Perturbations

no code implementations24 Jul 2023 Yi Han, Matthew Chan, Eric Wengrowski, Zhuohuan Li, Nils Ole Tippenhauer, Mani Srivastava, Saman Zonouz, Luis Garcia

We demonstrate that the dynamic nature of EvilEye enables attackers to adapt adversarial examples across a variety of objects with a significantly higher ASR compared to state-of-the-art physical world attack frameworks.

Eagle: End-to-end Deep Reinforcement Learning based Autonomous Control of PTZ Cameras

1 code implementation10 Apr 2023 Sandeep Singh Sandha, Bharathan Balaji, Luis Garcia, Mani Srivastava

Existing approaches for autonomous control of pan-tilt-zoom (PTZ) cameras use multiple stages where object detection and localization are performed separately from the control of the PTZ mechanisms.

Automatic Concept Extraction for Concept Bottleneck-based Video Classification

no code implementations21 Jun 2022 Jeya Vikranth Jeyakumar, Luke Dickens, Luis Garcia, Yu-Hsi Cheng, Diego Ramirez Echavarria, Joseph Noor, Alessandra Russo, Lance Kaplan, Erik Blasch, Mani Srivastava

CoDEx identifies a rich set of complex concept abstractions from natural language explanations of videos-obviating the need to predefine the amorphous set of concepts.

NS3: Neuro-Symbolic Semantic Code Search

1 code implementation21 May 2022 Shushan Arakelyan, Anna Hakhverdyan, Miltiadis Allamanis, Luis Garcia, Christophe Hauser, Xiang Ren

We compare our model - NS3 (Neuro-Symbolic Semantic Search) - to a number of baselines, including state-of-the-art semantic code retrieval methods, and evaluate on two datasets - CodeSearchNet and Code Search and Question Answering.

PhysioGAN: Training High Fidelity Generative Model for Physiological Sensor Readings

no code implementations25 Apr 2022 Moustafa Alzantot, Luis Garcia, Mani Srivastava

Generative models such as the variational autoencoder (VAE) and the generative adversarial networks (GAN) have proven to be incredibly powerful for the generation of synthetic data that preserves statistical properties and utility of real-world datasets, especially in the context of image and natural language text.

Using DeepProbLog to perform Complex Event Processing on an Audio Stream

no code implementations15 Oct 2021 Marc Roig Vilamala, Tianwei Xing, Harrison Taylor, Luis Garcia, Mani Srivastava, Lance Kaplan, Alun Preece, Angelika Kimmig, Federico Cerutti

We also demonstrate that our approach is capable of training even with a dataset that has a moderate proportion of noisy data.

An Experimentation Platform for Explainable Coalition Situational Understanding

no code implementations27 Oct 2020 Katie Barrett-Powell, Jack Furby, Liam Hiley, Marc Roig Vilamala, Harrison Taylor, Federico Cerutti, Alun Preece, Tianwei Xing, Luis Garcia, Mani Srivastava, Dave Braines

We present an experimentation platform for coalition situational understanding research that highlights capabilities in explainable artificial intelligence/machine learning (AI/ML) and integration of symbolic and subsymbolic AI/ML approaches for event processing.

A Hybrid Neuro-Symbolic Approach for Complex Event Processing

no code implementations7 Sep 2020 Marc Roig Vilamala, Harrison Taylor, Tianwei Xing, Luis Garcia, Mani Srivastava, Lance Kaplan, Alun Preece, Angelika Kimmig, Federico Cerutti

We demonstrate this comparing our approach against a pure neural network approach on a dataset based on Urban Sounds 8K.
