Anthropic's AI-Led DNA Discovery Sparks Scientific Debate and Originality Concerns

Anthropic's AI-Led DNA Discovery Sparks Scientific Debate and Originality Concerns

Anthropic, the AI and research company behind Claude, announced that its biology research lab used AI agents to discover a 'novel enzyme system' in viral DNA, similar to gene-editing tools like CRISPR Cas-9. Dario Amodei, Anthropic's chief executive, stated that Claude made this discovery with 'only high-level direction' from scientists. However, this announcement has generated skepticism and controversy within the scientific community. Some experts, like Aaron Engelhart, an associate professor at the University of Minnesota, view the finding as early and incremental, lacking a clear mechanistic picture or practical applications. Furthermore, Mario Rodríguez Mestre, a doctoral researcher, claimed that his unpublished research describes the same viral signatures, raising questions about the originality of the AI's discovery and whether Claude might have been exposed to his work. Anthropic's researchers tasked 950 AI agents to search a massive DNA database for 'interesting new examples' of reverse transcript...

AI Bias Mitigation Efforts May Reduce Model Confidence Rather Than Correcting Underlying Preferences

AI Bias Mitigation Efforts May Reduce Model Confidence Rather Than Correcting Underlying Preferences

Research indicates that current methods for mitigating bias in large language models (LLMs), particularly activation steering, may not be effectively correcting the models' underlying biases. Instead, these methods appear to reduce the models' confidence, leading to an increased tendency to abstain from answering or to provide more generalized, less specific responses. This effect is observed across various LLMs, including Llama-3.1-8B, Falcon3-7B, Qwen3.5-9B, and Ministral-3-8B. When models are given an option to abstain, steering towards debiasing directions significantly increases the probability of choosing the abstain option. In scenarios where abstention is not an option, the steering leads to an equilibration of answer probabilities, increasing entropy and decreasing overall confidence. This suggests that the debiasing directions identified in latent space are highly aligned with model confidence rather than solely targeting and correcting biased preferences.

Isotropic Gaussian Processes Enhance High-Dimensional Bayesian Optimization

Isotropic Gaussian Processes Enhance High-Dimensional Bayesian Optimization

Researchers Wei-Ting Tang, Madhav Muthyala, and Joel A. Paulson have introduced Iso-BO, a modified approach to high-dimensional Bayesian optimization (HDBO) that utilizes isotropic Gaussian processes (GPs). Traditional Bayesian optimization often employs automatic relevance determination (ARD) in its Gaussian process surrogates, fitting a separate lengthscale for each input coordinate. This flexibility is beneficial when coordinate-wise smoothness varies and sufficient data is available to learn these differences. However, in scenarios with limited observations relative to the input dimension, estimating numerous ARD lengthscales can be challenging. Iso-BO addresses this by replacing the ARD GP with an isotropic GP, which uses a single shared lengthscale while maintaining the integrity of the surrounding Bayesian optimization pipeline. This change aims to improve the learning of a useful surrogate from limited data, a critical aspect of HDBO, by simplifying the covariance structure estimation.
