Realistic Scatterer Based Adversarial Attacks on SAR Image Classifiers

no code implementations5 Dec 2023 Tian Ye, Rajgopal Kannan, Viktor Prasanna, Carl Busart, Lance Kaplan

Instead, adversarial attacks should be able to be implemented by physical actions, for example, placing additional false objects as scatterers around the on-ground target to perturb the SAR image and fool the SAR ATR.

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.

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.

NSL: Hybrid Interpretable Learning From Noisy Raw Data

no code implementations9 Dec 2020 Daniel Cunnington, Alessandra Russo, Mark Law, Jorge Lobo, Lance Kaplan

Using the scoring function of FastLAS, NSL searches for short, interpretable rules that generalise over such noisy examples.

A General Framework for Distributed Inference with Uncertain Models

no code implementations20 Nov 2020 James Z. Hare, Cesar A. Uribe, Lance Kaplan, Ali Jadbabaie

Non-Bayesian social learning theory provides a framework that solves this problem in an efficient manner by allowing the agents to sequentially communicate and update their beliefs for each hypothesis over the network.

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.

Uncertainty-Aware Deep Classifiers using Generative Models

no code implementations7 Jun 2020 Murat Sensoy, Lance Kaplan, Federico Cerutti, Maryam Saleki

Some recent approaches quantify classification uncertainty directly by training the model to output high uncertainty for the data samples close to class boundaries or from the outside of the training distribution.

Spherical Text Embedding

1 code implementation NeurIPS 2019 Yu Meng, Jiaxin Huang, Guangyuan Wang, Chao Zhang, Honglei Zhuang, Lance Kaplan, Jiawei Han

While text embeddings are typically learned in the Euclidean space, directional similarity is often more effective in tasks such as word similarity and document clustering, which creates a gap between the training stage and usage stage of text embedding.

Quantifying Classification Uncertainty using Regularized Evidential Neural Networks

no code implementations15 Oct 2019 Xujiang Zhao, Yuzhe Ou, Lance Kaplan, Feng Chen, Jin-Hee Cho

However, an ENN is trained as a black box without explicitly considering different types of inherent data uncertainty, such as vacuity (uncertainty due to a lack of evidence) or dissonance (uncertainty due to conflicting evidence).

Non-Bayesian Social Learning with Uncertain Models

no code implementations9 Sep 2019 James Z. Hare, Cesar A. Uribe, Lance Kaplan, Ali Jadbabaie

Non-Bayesian social learning theory provides a framework that models distributed inference for a group of agents interacting over a social network.

Prior Activation Distribution (PAD): A Versatile Representation to Utilize DNN Hidden Units

no code implementations5 Jul 2019 Lakmal Meegahapola, Vengateswaran Subramaniam, Lance Kaplan, Archan Misra

In this paper, we introduce the concept of Prior Activation Distribution (PAD) as a versatile and general technique to capture the typical activation patterns of hidden layer units of a Deep Neural Network used for classification tasks.

Uncertainty Aware AI ML: Why and How

no code implementations20 Sep 2018 Lance Kaplan, Federico Cerutti, Murat Sensoy, Alun Preece, Paul Sullivan

This paper argues the need for research to realize uncertainty-aware artificial intelligence and machine learning (AI\&ML) systems for decision support by describing a number of motivating scenarios.

Probabilistic Logic Programming with Beta-Distributed Random Variables

1 code implementation20 Sep 2018 Federico Cerutti, Lance Kaplan, Angelika Kimmig, Murat Sensoy

We enable aProbLog---a probabilistic logical programming approach---to reason in presence of uncertain probabilities represented as Beta-distributed random variables.

AspEm: Embedding Learning by Aspects in Heterogeneous Information Networks

no code implementations5 Mar 2018 Yu Shi, Huan Gui, Qi Zhu, Lance Kaplan, Jiawei Han

Therefore, we are motivated to propose a novel embedding learning framework---AspEm---to preserve the semantic information in HINs based on multiple aspects.

Identifying Semantically Deviating Outlier Documents

no code implementations EMNLP 2017 Honglei Zhuang, Chi Wang, Fangbo Tao, Lance Kaplan, Jiawei Han

A document outlier is a document that substantially deviates in semantics from the majority ones in a corpus.
