Exploiting Class Probabilities for Black-Box Sentence-Level Attacks
Background Text classification models have become increasingly prevalent in cybersecurity applications, but remain susceptible to adversarial examples (e.g., carefully crafted sentences with human-unrecognizable changes to the inputs, that are misclassified). Adversarial attacks provide profound insights into the classifiers’ vulnerabilities,...

Adversarial Text Purification: Large Language Model Approach for Defense
Background Adversarial purification is a defense mechanism for safe-guarding classifiers against adversarial attacks without knowing the type of attacks or training of the classifier. These techniques analyze and eliminate adversarial perturbations from the attacked inputs, and help to restore purified samples that retain similarity to the attacked...

Structured Data Extraction Using Large Language Models
Unmet Need: Method in Long-Form data extraction for LLMs Large Language Models (LLMs) excel in Natural Language Process (NLPs) tasks but face challenges in extracting information from large databases effectively. Current practices fail to address the inherent limitations of LLMs, resulting in suboptimal performance for long-form data extraction tasks. Researchers...
