The title of a now-deleted Reddit post read simply: "V2 of a Paul Chadeisson model I've been training". Just below sat three digital renderings of mountain-sized sci-fi cityscapes. Zooming in on them exposed finer details as the glitchy outputs of an artificial intelligence prompt-based image program, but they were nonetheless impressive. The renderings were stylistic replications of the work of Paul Chadeisson, a freelance conceptual artist who's worked on major film, video game, and streaming productions like Black Adam, Cyberpunk 2077, Love, Death & Robots, and the upcoming Dune: Part II. The user who created the now-deleted images had done so by training an AI model explicitly on Chadeisson's work.

The superior performance of supervised relation extraction (RE) methods heavily relies on a large amount of gold standard data. Recent zero-shot relation extraction methods converted the RE task to other NLP tasks and used off-the-shelf models of these NLP tasks to directly perform inference on the test data without using a large amount of RE annotation data. A potentially valuable by-product of these methods is the large-scale silver standard data. However, there is no further investigation on the use of potentially valuable silver standard data. In this paper, we propose to first detect a small amount of clean data from silver standard data and then use the selected clean data to finetune the pretrained model. We then use the finetuned model to infer relation types. We also propose a class-aware clean data detection module to consider class information when selecting clean data. The experimental results show that our method can outperform the baseline by 12% and 11% on TACRED and Wiki80 dataset in the zero-shot RE task. By using extra silver standard data of different distributions, the performance can be further improved.

One of the challenges of developing a summarization model arises from the difficulty in measuring the factual inconsistency of the generated text. In this study, we reinterpret the decoder overconfidence-regularizing objective suggested in (Miao et al., 2021) as a hallucination risk measurement to better estimate the quality of generated summaries. We propose a reference-free metric, HaRiM+, which only requires an off-the-shelf summarization model to compute the hallucination risk based on token likelihoods. Deploying it requires no additional training of models or ad-hoc modules, which usually need alignment to human judgments. For summary-quality estimation, HaRiM+ records state-of-the-art correlation to human judgment on three summary-quality annotation sets: FRANK, QAGS, and SummEval. We hope that our work, which merits the use of summarization models, facilitates the progress of both automated evaluation and generation of summary.

The final search query for the Systematic Literature Review (SLR) was conducted on 15th July 2022. Initially, we extracted 1707 journal and conference articles from the Scopus and Web of Science databases. Inclusion and exclusion criteria were then applied, and 58 articles were selected for the SLR. The findings show four dimensions that shape the AI explanation, which are format (explanation representation format), completeness (explanation should contain all required information, including the supplementary information), accuracy (information regarding the accuracy of the explanation), and currency (explanation should contain recent information). Moreover, along with the automatic representation of the explanation, the users can request additional information if needed. We have also found five dimensions of XAI effects: trust, transparency, understandability, usability, and fairness. In addition, we investigated current knowledge from selected articles to problematize future research agendas as research questions along with possible research paths. Consequently, a comprehensive framework of XAI and its possible effects on user behavior has been developed.

Okay, let's talk about killer robots. It's a concept that long ago leapt from the pages of science fiction to reality, depending on how loose a definition you use for "robot." Military drones abandoned Asimov's First Law of Robotics -- "A robot may not injure a human being or, through inaction, allow a human being to come to harm" -- decades ago. The topic has been simmering again of late due to the increasing prospect of killer robots in domestic law enforcement. One of the era's best known robot makers, Boston Dynamics, raised some public policy red flags when it showcased footage of its Spot robot being deployed as part of Massachusetts State Police training exercises on our stage back in 2019.

Risk prediction has permeated many aspects of modern life, including health care. Algorithms developed using advanced statistical methods have been used to identify hospitalized adults at risk of clinical deterioration, reduce hospital readmission rates, and improve resource allocation and health care use. These methods have also been used to develop predictive models for overdose risk among specific patient populations. Most of these overdose-specific applications, however, have been limited to health care settings using health care utilization or insurance claims data. State and local governments are increasingly integrating health- and non-health-sector data for public health purposes, creating an opportunity to use these data to improve overdose risk prediction models.

Harvey, a startup building what it describes as a "copilot for lawyers," today emerged from stealth with $5 million in funding led by the OpenAI Startup Fund, the tranche through which OpenAI and its partners are investing in early-stage AI companies tackling major problems. Also participating in the round was Jeff Dean, the lead of Google AI, Google's AI research division. Harvey was founded by Winston Weinberg, a former securities and antitrust litigator at law firm O'Melveny & Myers, and Gabriel Pereyra, previously a research scientist at DeepMind, Google Brain (another of Google's AI groups) and Meta AI. Weinberg and Pereyra are roomates -- Pereyra showed Weinberg OpenAI's GPT-3 text-generating system and Weinberg realized that it could be used to improve legal workflows. "Our product provides lawyers with a natural language interface for their existing legal workflows," Pereyra told TechCrunch in an email interview. "Instead of manually editing legal documents or performing legal research, Harvey enables lawyers to describe the task they wish to accomplish in simple instructions and receive the generated result.

The lawsuit has echoes in the last few decades of the technology industry. In the 1990s and into the 2000s, Microsoft fought the rise of open source software, seeing it as an existential threat to the future of the company's business. As the importance of open source grew, Microsoft embraced it and even acquired GitHub, a home to open source programmers and a place where they built and stored their code. Nearly every new generation of technology -- even online search engines -- has faced similar legal challenges. Often, "there is no statute or case law that covers it," said Bradley J. Hulbert, an intellectual property lawyer who specializes in this increasingly important area of the law.

Cyber deception is emerging as a promising approach to defending networks and systems against attackers and data thieves. However, despite being relatively cheap to deploy, the generation of realistic content at scale is very costly, due to the fact that rich, interactive deceptive technologies are largely hand-crafted. With recent improvements in Machine Learning, we now have the opportunity to bring scale and automation to the creation of realistic and enticing simulated content. In this work, we propose a framework to automate the generation of email and instant messaging-style group communications at scale. Such messaging platforms within organisations contain a lot of valuable information inside private communications and document attachments, making them an enticing target for an adversary. We address two key aspects of simulating this type of system: modelling when and with whom participants communicate, and generating topical, multi-party text to populate simulated conversation threads. We present the LogNormMix-Net Temporal Point Process as an approach to the first of these, building upon the intensity-free modeling approach of Shchur et al. to create a generative model for unicast and multi-cast communications. We demonstrate the use of fine-tuned, pre-trained language models to generate convincing multi-party conversation threads. A live email server is simulated by uniting our LogNormMix-Net TPP (to generate the communication timestamp, sender and recipients) with the language model, which generates the contents of the multi-party email threads. We evaluate the generated content with respect to a number of realism-based properties, that encourage a model to learn to generate content that will engage the attention of an adversary to achieve a deception outcome.

The increasing deployment of artificial intelligence (AI) tools to inform decision making across diverse areas including healthcare, employment, social benefits, and government policy, presents a serious risk for disabled people, who have been shown to face bias in AI implementations. While there has been significant work on analysing and mitigating algorithmic bias, the broader mechanisms of how bias emerges in AI applications are not well understood, hampering efforts to address bias where it begins. In this article, we illustrate how bias in AI-assisted decision making can arise from a range of specific design decisions, each of which may seem self-contained and non-biasing when considered separately. These design decisions include basic problem formulation, the data chosen for analysis, the use the AI technology is put to, and operational design elements in addition to the core algorithmic design. We draw on three historical models of disability common to different decision-making settings to demonstrate how differences in the definition of disability can lead to highly distinct decisions on each of these aspects of design, leading in turn to AI technologies with a variety of biases and downstream effects. We further show that the potential harms arising from inappropriate definitions of disability in fundamental design stages are further amplified by a lack of transparency and disabled participation throughout the AI design process. Our analysis provides a framework for critically examining AI technologies in decision-making contexts and guiding the development of a design praxis for disability-related AI analytics. We put forth this article to provide key questions to facilitate disability-led design and participatory development to produce more fair and equitable AI technologies in disability-related contexts.
