Forget What You Know about LLMs Evaluations - LLMs are Like a Chameleon

EMNLP 2025

Large language models (LLMs) often appear to excel on public benchmarks, but these high scores may mask an overreliance on dataset-specific surface cues rather than true language understanding. We introduce the **Chameleon Benchmark Overfit Detector (C-BOD)**, a meta-evaluation framework designed to

TTTS: Tree Test Time Simulation for Enhancing Decision Tree Robustness against Adversarial Examples

AAAI 2024technical

Decision trees are widely used for addressing learning tasks involving tabular data. Yet, they are susceptible to adversarial attacks. In this paper, we present Tree Test Time Simulation (TTTS), a novel inference-time methodology that incorporates Monte Carlo simulations into decision trees to enhan…
