PACOL: Poisoning Attacks Against Continual Learners

no code implementations18 Nov 2023 Huayu Li, Gregory Ditzler

In this work, we demonstrate that continual learning systems can be manipulated by malicious misinformation and present a new category of data poisoning attacks specific for continual learners, which we refer to as {\em Poisoning Attacks Against Continual Learners} (PACOL).

Knowledge Distillation Under Ideal Joint Classifier Assumption

no code implementations19 Apr 2023 Huayu Li, Xiwen Chen, Gregory Ditzler, Janet Roveda, Ao Li

Within this context, softmax regression representation learning serves as a widely embraced approach, leveraging a pre-established teacher network to guide the learning process of a diminutive student network.

A Maximum Log-Likelihood Method for Imbalanced Few-Shot Learning Tasks

1 code implementation26 Nov 2022 Samuel Hess, Gregory Ditzler

In this work, we investigate the distributions of trained few-shot features and demonstrate that they can be roughly approximated as exponential distributions.

DeScoD-ECG: Deep Score-Based Diffusion Model for ECG Baseline Wander and Noise Removal

1 code implementation31 Jul 2022 Huayu Li, Gregory Ditzler, Janet Roveda, Ao Li

Significance: This study is one of the first to extend the conditional diffusion-based generative model for ECG noise removal, and the DeScoD-ECG has the potential to be widely used in biomedical applications.

ProtoShotXAI: Using Prototypical Few-Shot Architecture for Explainable AI

1 code implementation22 Oct 2021 Samuel Hess, Gregory Ditzler

A user explores the manifold by perturbing the input features of a query sample and recording the response for a subset of exemplars from any class.

Adversarial Filters for Secure Modulation Classification

no code implementations15 Aug 2020 Alex Berian, Kory Staab, Noel Teku, Gregory Ditzler, Tamal Bose, Ravi Tandon

This paper considers the problem of secure modulation classification, where a transmitter (Alice) wants to maximize MC accuracy at a legitimate receiver (Bob) while minimizing MC accuracy at an eavesdropper (Eve).

Edge-Guided Occlusion Fading Reduction for a Light-Weighted Self-Supervised Monocular Depth Estimation

2 code implementations26 Nov 2019 Kuo-Shiuan Peng, Gregory Ditzler, Jerzy Rozenblit

In this paper, we propose a novel Edge-Guided post-processing to reduce the occlusion fading issue for self-supervised monocular depth estimation.
