Safety Tax: Safety Alignment Makes Your Large Reasoning Models Less Reasonable
Safety alignment is an important procedure before the official deployment of a Large Language Model (LLM). While safety alignment has been extensively studied for LLM, there is still a large research gap for Large Reasoning Models (LRMs) that equip with improved reasoning capability. We in this paper systematically examine a simplified pipeline for producing safety aligned LRMs. With our evaluation of various LRMs, we deliver two main findings: i) Safety alignment can be done upon the LRM to re…

A good counter-explanation from @…, although it’s not entirely consistent with the data: if this were merely aging vehicles, we’d expect to see a slow, steady decline. But we don’t; we see a •very• sharp turnaround that coincides precisely with Musk’s fascism entering full public view, and not with any sort of sudden aging event in the vehicles.
But yes, surely normal depreciation is a contributing factor as well.

It’s Alexandria Ocasio-Cortez.
Since this is a grassroots campaign, I want to be transparent with you. 
Our fundraising hit an unexpected dip these last few days
– it happens sometimes,
and I don’t want to alarm you!
But I do want to share why this is important.
Unlike most other House campaigns, we operate differently and invest in community organizing year-round and full-time permanent staff.

Donate to AOC.
Alexandria is fighting for progressive policies that can help create social, racial, and economic justice for all. That's why she's taking $0 from corporations and lobbyists and is relying on the grassroots to power her campaign.

¿Por qué le llamamos "arañazo" a los "rasguños" si las arañas no arañan? 🤯
¿O alguien acaso ha visto alguna vez a una araña arañando?
¿Quién me lo puede explicar? 🤔

Another of my forays into AI ethics is just out! This time the focus is on the ethics (or lack thereof) of Reinforcement Learning Feedback (RLF) techniques aimed at increasing the 'alignment' of LLMs.
The paper is fruit of the joint work of a great team of collaborators, among whom @… and @…

Helpful, harmless, honest? Sociotechnical limits of AI alignment and safety through Reinforcement Learning from Human Feedback - Ethics and Information Technology
This paper critically evaluates the attempts to align Artificial Intelligence (AI) systems, especially Large Language Models (LLMs), with human values and intentions through Reinforcement Learning from Feedback methods, involving either human feedback (RLHF) or AI feedback (RLAIF). Specifically, we show the shortcomings of the broadly pursued alignment goals of honesty, harmlessness, and helpfulness. Through a multidisciplinary sociotechnical critique, we examine both the theoretical underpinni…

Learning Intrinsic Alignments from Local Galaxy Environments
We present DELTA (Data-Empiric Learned Tidal Alignments), a deep learning model that isolates galaxy intrinsic alignments (IAs) from weak lensing distortions using only observational data. The model uses an Equivariant Graph Neural Network backbone suitable for capturing information from the local galaxy environment, in conjunction with a probabilistic orientation output. Unlike parametric models, DELTA flexibly learns the relationship between galaxy shapes and their local environments, without…

Why LLM Safety Guardrails Collapse After Fine-tuning: A Similarity Analysis Between Alignment and Fine-tuning Datasets
Recent advancements in large language models (LLMs) have underscored their vulnerability to safety alignment jailbreaks, particularly when subjected to downstream fine-tuning. However, existing mitigation strategies primarily focus on reactively addressing jailbreak incidents after safety guardrails have been compromised, removing harmful gradients during fine-tuning, or continuously reinforcing safety alignment throughout fine-tuning. As such, they tend to overlook a critical upstream factor: …
