UnpredictaBench: A Benchmark for Evaluating Distributional Randomness in LLMs

UnpredictaBench has been introduced as a benchmark aimed at evaluating the distributional randomness capabilities of large language models (LLMs). This evaluation is crucial as LLMs are increasingly utilized in simulations that require capturing the unpredictability of real-world systems, rather than converging on a single plausible answer. The benchmark includes 448 problems that assess the models' ability to sample from various target distributions.

The Piggyback Hypothesis of Generalization: Explaining and Mitigating Emergent Misalignment

The Piggyback Hypothesis of Generalization proposes a mechanism to explain emergent misalignment (EM) in large language models (LLMs), particularly how finetuning on specific tasks can lead to misalignment in unrelated domains. The study introduces Token-Regularized Finetuning (TReFT) as a method to mitigate EM while preserving in-domain learning, validated through experiments on models like Llama-3.1-8B.
