Holistic Safety and Responsibility Evaluations of Advanced AI Models

arXiv.org Artificial Intelligence

Safety and responsibility evaluations of advanced AI models are a critical but developing field of research and practice. In the development of Google DeepMind's advanced AI models, we innovated on and applied a broad set of approaches to safety evaluation. In this report, we summarise and share elements of our evolving approach as well as lessons learned for a broad audience. Key lessons learned include: First, theoretical underpinnings and frameworks are invaluable to organise the breadth of risk domains, modalities, forms, metrics, and goals. Second, theory and practice of safety evaluation development each benefit from collaboration to clarify goals, methods and challenges, and facilitate the transfer of insights between different stakeholders and disciplines. Third, similar key methods, lessons, and institutions apply across the range of concerns in responsibility and safety - including established and emerging harms. For this reason it is important that a wide range of actors working on safety evaluation and safety research communities work together to develop, refine and implement novel evaluation approaches and best practices, rather than operating in silos. The report concludes with outlining the clear need to rapidly advance the science of evaluations, to integrate new evaluations into the development and governance of AI, to establish scientifically-grounded norms and standards, and to promote a robust evaluation ecosystem.


Using Graph Neural Networks to Predict Local Culture

arXiv.org Artificial Intelligence

Urban research has long recognized that neighbourhoods are dynamic and relational. However, lack of data, methodologies, and computer processing power have hampered a formal quantitative examination of neighbourhood relational dynamics. To make progress on this issue, this study proposes a graph neural network (GNN) approach that permits combining and evaluating multiple sources of information about internal characteristics of neighbourhoods, their past characteristics, and flows of groups among them, potentially providing greater expressive power in predictive models. By exploring a public large-scale dataset from Yelp, we show the potential of our approach for considering structural connectedness in predicting neighbourhood attributes, specifically to predict local culture. Results are promising from a substantive and methodologically point of view. Substantively, we find that either local area information (e.g. area demographics) or group profiles (tastes of Yelp reviewers) give the best results in predicting local culture, and they are nearly equivalent in all studied cases. Methodologically, exploring group profiles could be a helpful alternative where finding local information for specific areas is challenging, since they can be extracted automatically from many forms of online data. Thus, our approach could empower researchers and policy-makers to use a range of data sources when other local area information is lacking.


LLMs as Writing Assistants: Exploring Perspectives on Sense of Ownership and Reasoning

arXiv.org Artificial Intelligence

Sense of ownership in writing confines our investment of thoughts, time, and contribution, leading to attachment to the output. However, using writing assistants introduces a mental dilemma, as some content isn't directly our creation. For instance, we tend to credit Large Language Models (LLMs) more in creative tasks, even though all tasks are equal for them. Additionally, while we may not claim complete ownership of LLM-generated content, we freely claim authorship. We conduct a short survey to examine these issues and understand underlying cognitive processes in order to gain a better knowledge of human-computer interaction in writing and improve writing aid systems.


AI-Generated Video of the Mona Lisa Rapping Sparks Strong Reactions From Viewers

TIME - Tech

The internet has reacted strongly to an artificial intelligence-generated video of the famous subject of Leonardo Da Vinci's Mona Lisa painting singing along to a rap that actor Anne Hathaway wrote and performed. The polarizing clip, which has elicited reactions online ranging from humor to horror, is one of the tricks of Microsoft's new AI technology called VASA-1. The technology is able to generate lifelike talking faces of virtual characters using a single image and speech audio clip. The AI can make cartoon characters, photographs, and paintings sing or talk, as evidenced in footage Microsoft released as part of research published on April 16. In the most viral clip, the woman in the Mona Lisa painting sings, her mouth, eyes and face moving, to "Paparazzi," a rap Hathaway wrote and performed on Conan O'Brien's talk show in 2011.


Sex offender banned from using AI tools in landmark UK case

The Guardian

A sex offender convicted of making more than 1,000 indecent images of children has been banned from using any "AI creating tools" for the next five years in the first known case of its kind. Anthony Dover, 48, was ordered by a UK court "not to use, visit or access" artificial intelligence generation tools without the prior permission of police as a condition of a sexual harm prevention order imposed in February. The ban prohibits him from using tools such as text-to-image generators, which can make lifelike pictures based on a written command, and "nudifying" websites used to make explicit "deepfakes". Dover, who was given a community order and 200 fine, has also been explicitly ordered not to use Stable Diffusion software, which has reportedly been exploited by paedophiles to create hyper-realistic child sexual abuse material, according to records from a sentencing hearing at Poole magistrates court. The case is the latest in a string of prosecutions where AI generation has emerged as an issue and follows months of warnings from charities over the proliferation of AI-generated sexual abuse imagery.


AdvPrompter: Fast Adaptive Adversarial Prompting for LLMs

arXiv.org Artificial Intelligence

While recently Large Language Models (LLMs) have achieved remarkable successes, they are vulnerable to certain jailbreaking attacks that lead to generation of inappropriate or harmful content. Manual red-teaming requires finding adversarial prompts that cause such jailbreaking, e.g. by appending a suffix to a given instruction, which is inefficient and time-consuming. On the other hand, automatic adversarial prompt generation often leads to semantically meaningless attacks that can easily be detected by perplexity-based filters, may require gradient information from the TargetLLM, or do not scale well due to time-consuming discrete optimization processes over the token space. In this paper, we present a novel method that uses another LLM, called the AdvPrompter, to generate human-readable adversarial prompts in seconds, $\sim800\times$ faster than existing optimization-based approaches. We train the AdvPrompter using a novel algorithm that does not require access to the gradients of the TargetLLM. This process alternates between two steps: (1) generating high-quality target adversarial suffixes by optimizing the AdvPrompter predictions, and (2) low-rank fine-tuning of the AdvPrompter with the generated adversarial suffixes. The trained AdvPrompter generates suffixes that veil the input instruction without changing its meaning, such that the TargetLLM is lured to give a harmful response. Experimental results on popular open source TargetLLMs show state-of-the-art results on the AdvBench dataset, that also transfer to closed-source black-box LLM APIs. Further, we demonstrate that by fine-tuning on a synthetic dataset generated by AdvPrompter, LLMs can be made more robust against jailbreaking attacks while maintaining performance, i.e. high MMLU scores.


A Practical Multilevel Governance Framework for Autonomous and Intelligent Systems

arXiv.org Artificial Intelligence

Autonomous and intelligent systems (AIS) facilitate a wide range of beneficial applications across a variety of different domains. However, technical characteristics such as unpredictability and lack of transparency, as well as potential unintended consequences, pose considerable challenges to the current governance infrastructure. Furthermore, the speed of development and deployment of applications outpaces the ability of existing governance institutions to put in place effective ethical-legal oversight. New approaches for agile, distributed and multilevel governance are needed. This work presents a practical framework for multilevel governance of AIS. The framework enables mapping actors onto six levels of decision-making including the international, national and organizational levels. Furthermore, it offers the ability to identify and evolve existing tools or create new tools for guiding the behavior of actors within the levels. Governance mechanisms enable actors to shape and enforce regulations and other tools, which when complemented with good practices contribute to effective and comprehensive governance.


Recourse for reclamation: Chatting with generative language models

arXiv.org Artificial Intelligence

Researchers and developers increasingly rely on toxicity scoring to moderate generative language model outputs, in settings such as customer service, information retrieval, and content generation. However, toxicity scoring may render pertinent information inaccessible, rigidify or "value-lock" cultural norms, and prevent language reclamation processes, particularly for marginalized people. In this work, we extend the concept of algorithmic recourse to generative language models: we provide users a novel mechanism to achieve their desired prediction by dynamically setting thresholds for toxicity filtering. Users thereby exercise increased agency relative to interactions with the baseline system. A pilot study ($n = 30$) supports the potential of our proposed recourse mechanism, indicating improvements in usability compared to fixed-threshold toxicity-filtering of model outputs. Future work should explore the intersection of toxicity scoring, model controllability, user agency, and language reclamation processes -- particularly with regard to the bias that many communities encounter when interacting with generative language models.


The big tech firms want an AI monopoly – but the UK watchdog can bring them to heel John Naughton

The Guardian

"Monopoly," said Peter Thiel, Silicon Valley's answer to Darth Vader, "is the condition of every successful business." This aspiration is widely shared by Gamman, the new acronynm for the Valley's giants – Google, Apple, Microsoft, Meta, Amazon and Nvidia. And the arrival of AI has sharpened the appetite of each for attaining that blessed state before the others get there. One symptom of their anxiety is the way they have been throwing unconscionable amounts of money at the 70-odd generative AI startups that have mushroomed since it became clear that AI was going to be the new new thing. Microsoft reportedly put 13bn (about 10.4bn) into OpenAI, for example, but it was also the lead investor in a 1.3bn funding round for Inflection, Deepmind co-founder Mustafa Suleyman's startup.


A Framework for Feasible Counterfactual Exploration incorporating Causality, Sparsity and Density

arXiv.org Artificial Intelligence

The imminent need to interpret the output of a Machine Learning model with counterfactual (CF) explanations - via small perturbations to the input - has been notable in the research community. Although the variety of CF examples is important, the aspect of them being feasible at the same time, does not necessarily apply in their entirety. This work uses different benchmark datasets to examine through the preservation of the logical causal relations of their attributes, whether CF examples can be generated after a small amount of changes to the original input, be feasible and actually useful to the end-user in a real-world case. To achieve this, we used a black box model as a classifier, to distinguish the desired from the input class and a Variational Autoencoder (VAE) to generate feasible CF examples. As an extension, we also extracted two-dimensional manifolds (one for each dataset) that located the majority of the feasible examples, a representation that adequately distinguished them from infeasible ones. For our experimentation we used three commonly used datasets and we managed to generate feasible and at the same time sparse, CF examples that satisfy all possible predefined causal constraints, by confirming their importance with the attributes in a dataset.
