Large Language Models for Conducting Advanced Text Analytics Information Systems Research

no code implementations27 Dec 2023 Benjamin M. Ampel, Chi-Heng Yang, James Hu, Hsinchun Chen

To assist IS research in understanding how to operationalize LLMs, we propose a Text Analytics for Information Systems Research (TAISR) framework.

Multi-view Representation Learning from Malware to Defend Against Adversarial Variants

no code implementations25 Oct 2022 James Lee Hu, MohammadReza Ebrahimi, Weifeng Li, Xin Li, Hsinchun Chen

This provides an opportunity for the defenders (i. e., malware detectors) to detect the adversarial variants by utilizing more than one view of a malware file (e. g., source code view in addition to the binary view).

Predicting gene functions is a challenge for biologists in the post genomic era.

Single-Shot Black-Box Adversarial Attacks Against Malware Detectors: A Causal Language Model Approach

no code implementations3 Dec 2021 James Lee Hu, MohammadReza Ebrahimi, Hsinchun Chen

Given that most malware detectors enforce a query limit, this could result in generating non-realistic adversarial examples that are likely to be detected in practice due to lack of stealth.
