FakeInversion: Learning to Detect Images from Unseen Text-to-Image Models by Inverting Stable Diffusion
Cazenavette, George, Sud, Avneesh, Leung, Thomas, Usman, Ben
Due to the high potential for abuse of GenAI systems, the task of detecting synthetic images has recently become of great interest to the research community. Unfortunately, existing image-space detectors quickly become obsolete as new high-fidelity text-to-image models are developed at blinding speed. In this work, we propose a new synthetic image detector that uses features obtained by inverting an open-source pre-trained Stable Diffusion model. We show that these inversion features enable our detector to generalize well to unseen generators of high visual fidelity (e.g., DALL-E 3) even when the detector is trained only on lower fidelity fake images generated via Stable Diffusion. This detector achieves new state-of-the-art across multiple training and evaluation setups. Moreover, we introduce a new challenging evaluation protocol that uses reverse image search to mitigate stylistic and thematic biases in the detector evaluation. We show that the resulting evaluation scores align well with detectors' in-the-wild performance, and release these datasets as public benchmarks for future research.
Tailoring Generative AI Chatbots for Multiethnic Communities in Disaster Preparedness Communication: Extending the CASA Paradigm
Zhao, Xinyan, Sun, Yuan, Liu, Wenlin, Wong, Chau-Wai
This study is among the first to develop different prototypes of generative AI (GenAI) chatbots powered by GPT 4 to communicate hurricane preparedness information to diverse residents. Drawing from the Computers Are Social Actors (CASA) paradigm and the literature on disaster vulnerability and cultural tailoring, this study conducted a between-subjects experiment with 441 Black, Hispanic, and Caucasian residents of Florida. A computational analysis of chat logs (N = 7,848) shows that anthropomorphism and personalization are key communication topics in GenAI chatbot-user interactions. SEM results (N = 441) suggest that GenAI chatbots varying in tone formality and cultural tailoring significantly predict bot perceptions and, subsequently, hurricane preparedness outcomes. These results highlight the potential of using GenAI chatbots to improve diverse communities' disaster preparedness.
Global AI Governance in Healthcare: A Cross-Jurisdictional Regulatory Analysis
Chakraborty, Attrayee, Karhade, Mandar
Artificial Intelligence (AI) is being adopted across the world and promises a new revolution in healthcare. While AI-enabled medical devices in North America dominate 42.3% of the global market, the use of AI-enabled medical devices in other countries is still a story waiting to be unfolded. We aim to delve deeper into global regulatory approaches towards AI use in healthcare, with a focus on how common themes are emerging globally. We compare these themes to the World Health Organization's (WHO) regulatory considerations and principles on ethical use of AI for healthcare applications. Our work seeks to take a global perspective on AI policy by analyzing 14 legal jurisdictions including countries representative of various regions in the world (North America, South America, South East Asia, Middle East, Africa, Australia, and the Asia-Pacific). Our eventual goal is to foster a global conversation on the ethical use of AI in healthcare and the regulations that will guide it. We propose solutions to promote international harmonization of AI regulations and examine the requirements for regulating generative AI, using China and Singapore as examples of countries with well-developed policies in this area.
Fine-Tuned 'Small' LLMs (Still) Significantly Outperform Zero-Shot Generative AI Models in Text Classification
Bucher, Martin Juan Josรฉ, Martini, Marco
Generative AI offers a simple, prompt-based alternative to fine-tuning smaller BERT-style LLMs for text classification tasks. This promises to eliminate the need for manually labeled training data and task-specific model training. However, it remains an open question whether tools like ChatGPT can deliver on this promise. In this paper, we show that smaller, fine-tuned LLMs (still) consistently and significantly outperform larger, zero-shot prompted models in text classification. We compare three major generative AI models (ChatGPT with GPT-3.5/GPT-4 and Claude Opus) with several fine-tuned LLMs across a diverse set of classification tasks (sentiment, approval/disapproval, emotions, party positions) and text categories (news, tweets, speeches). We find that fine-tuning with application-specific training data achieves superior performance in all cases. To make this approach more accessible to a broader audience, we provide an easy-to-use toolkit alongside this paper. Our toolkit, accompanied by non-technical step-by-step guidance, enables users to select and fine-tune BERT-like LLMs for any classification task with minimal technical and computational effort.
Elon Musk drops lawsuit against OpenAI
Musk originally filed his lawsuit at the beginning of March, arguing that OpenAI had breached its commitment to early investors and the public to build AI for the benefit of humanity when it began making money. At the time, OpenAI executives blamed Musk's lawsuit on his not being a part of the company as it was seeing massive success. Musk did not immediately respond to a request for comment Tuesday. A spokesperson for OpenAI declined to comment.
Elon Musk Drops Suit Accusing OpenAI of Breaching Founding Mission
Elon Musk dropped a lawsuit alleging OpenAI and its chief executive officer Sam Altman breached a founding promise last year by prioritizing profits over humanity. The billionaire withdrew his complaint a day before a California judge was set to hear OpenAI's request for dismissal. Musk had accused the company of becoming a "de facto subsidiary" of Microsoft Corp. in violation of a founding agreement to be a non-profit that developed artificial intelligence "for the benefit of humanity." OpenAI and Musk have been engaged in a well-publicized battle since well before the court case. Musk was an early backer of the startup and part of its founding team, before he had a falling out with the company.
Elon Musk abruptly withdraws lawsuit against Sam Altman and OpenAI
Elon Musk has moved to dismiss his lawsuit accusing ChatGPT maker OpenAI and its CEO Sam Altman of abandoning the startup's original mission of developing artificial intelligence for the benefit of humanity. Musk launched the suit against Altman in February, and the case had been slowly working its way through the California court system. There was no indication until Tuesday that Musk planned to drop the suit; only a month ago, his lawyers filed a challenge that forced the judge hearing the case to remove himself. Musk's request for a dismissal contained no reason behind the decision. A San Francisco superior court judge was scheduled on Wednesday to hear Altman and OpenAI's argument for throwing the case out.
Musk withdraws his breach of contract lawsuit against OpenAI
Elon Musk dropped a lawsuit against OpenAI one day before a judge in California state court was set to hear OpenAI's request for dismissal. Musk's suit, which was filed in February, had accused OpenAI co-founders Sam Altman and Greg Brockman of violating the company's non-profit status and instead prioritizing profits over using AI to help humanity. In the 35-page suit, Musk had alleged that OpenAI had become a "closed-source de facto subsidiary" of Microsoft, which invested 13 billion in the company and owns a 49 percent stake. Microsoft uses OpenAI's technology to power Copilot, the company's generative AI tools that are deeply integrated in products like Windows and Office. OpenAI had reportedly requested for the lawsuit to be dismissed, arguing that Musk would use any information that emerged as a result to get access to the company's "proprietary records and technology."
Hey Elon, go ahead and ban Apple devices
Yesterday, following Apple's announcement of a partnership with OpenAI to integrate support for ChatGPT into the company's devices, Elon Musk did what he always does: he tweeted. The owner of X wrote, on X, that he would ban Apple devices at his companies "If Apple integrates OpenAI at the OS level.". And to that I say: Go right ahead. And while you're at it, remove your company's software from Apple's App Store too. Musk's companies (at least the major ones) currently include Tesla, SpaceX, X, X AI and Neuralink.
How to Think About Remedies in the Generative AI Copyright Cases
Some commentators are convinced these training data claims are sure winnersb; others are equally sure the use of works to train foundation models is fair use, especially if the datasets consist of digital copies of works found on the open Internet.c It may be years before courts decide these and other claims in these lawsuits. Virtually all complaints ask for awards of actual damages and disgorgement of profits attributable to infringement, prejudgment interest, attorney fees, and costs. Most ask for injunctive relief and any other remedy the court may deem just. In these respects, the complaints are quite ordinary. But three types of remedy claims merit special attention: claims for awards of statutory damages; court orders to destroy models trained on infringing works; and most bizarrely, court orders to establish a regulatory regime to oversee generative AI system operations.
