OpenAI is showing no signs of slowing down its recent pace of updates. On Wednesday, the company announced the expanded availability of ChatGPT Search. After rolling out the tool first to paid subscribers last fall, and then making it available to all logged-in free users at the end of 2024, now anyone can use ChatGPT Search with no account or sign-in necessary. "Like the logged-in experience, ChatGPT can search the web and get you fast, timely answers with links to relevant web sources directly in ChatGPT," OpenAI said. In most cases, ChatGPT will automatically search the web to source the most up-to-date information related to your question.

The author proposed Classification Accuracy Score -- a metric that is based on a performance of a discriminative model that is trained on samples obtained from the conditional generative model. The paper also discussed pros and cons of the proposed metric. The empirical study shows that a number of sota-level deep generative models fail to match the target distribution. Pros: While the idea has been proposed before in Shmelkov2018, it was not widely used in the field. The current paper points out some limitations of deep generative models as well as limitations currently used metrics, thus the paper delivers a significant contribution.

This study explores the implementation of large Quantum Restricted Boltzmann Machines (QRBMs), a key advancement in Quantum Machine Learning (QML), as generative models on D-Wave's Pegasus quantum hardware to address dataset imbalance in Intrusion Detection Systems (IDS). By leveraging Pegasus's enhanced connectivity and computational capabilities, a QRBM with 120 visible and 120 hidden units was successfully embedded, surpassing the limitations of default embedding tools. The QRBM synthesized over 1.6 million attack samples, achieving a balanced dataset of over 4.2 million records. Comparative evaluations with traditional balancing methods, such as SMOTE and RandomOversampler, revealed that QRBMs produced higher-quality synthetic samples, significantly improving detection rates, precision, recall, and F1 score across diverse classifiers. The study underscores the scalability and efficiency of QRBMs, completing balancing tasks in milliseconds. These findings highlight the transformative potential of QML and QRBMs as next-generation tools in data preprocessing, offering robust solutions for complex computational challenges in modern information systems.

Membership inference attacks (MIAs) determine whether certain data instances were used to train a model by exploiting the differences in how the model responds to seen versus unseen instances. This capability makes MIAs important in assessing privacy leakage within modern generative AI systems. However, this paper reveals an oversight in existing MIAs against \emph{distilled generative models}: attackers can no longer detect a teacher model's training instances individually when targeting the distilled student model, as the student learns from the teacher-generated data rather than its original member data, preventing direct instance-level memorization. Nevertheless, we find that student-generated samples exhibit a significantly stronger distributional alignment with teacher's member data than non-member data. This leads us to posit that MIAs \emph{on distilled generative models should shift from instance-level to distribution-level statistics}. We thereby introduce a \emph{set-based} MIA framework that measures \emph{relative} distributional discrepancies between student-generated data\emph{sets} and potential member/non-member data\emph{sets}, Empirically, distributional statistics reliably distinguish a teacher's member data from non-member data through the distilled model. Finally, we discuss scenarios in which our setup faces limitations.

Systems engineering (SE) is evolving with the availability of generative artificial intelligence (AI) and the demand for a systems-of-systems perspective, formalized under the purview of mission engineering (ME) in the US Department of Defense. Formulating ME problems is challenging because they are open-ended exercises that involve translation of ill-defined problems into well-defined ones that are amenable for engineering development. It remains to be seen to which extent AI could assist problem formulation objectives. To that end, this paper explores the quality and consistency of multi-purpose Large Language Models (LLM) in supporting ME problem formulation tasks, specifically focusing on stakeholder identification. We identify a relevant reference problem, a NASA space mission design challenge, and document ChatGPT-3.5's ability to perform stakeholder identification tasks. We execute multiple parallel attempts and qualitatively evaluate LLM outputs, focusing on both their quality and variability. Our findings portray a nuanced picture. We find that the LLM performs well in identifying human-focused stakeholders but poorly in recognizing external systems and environmental factors, despite explicit efforts to account for these. Additionally, LLMs struggle with preserving the desired level of abstraction and exhibit a tendency to produce solution specific outputs that are inappropriate for problem formulation. More importantly, we document great variability among parallel threads, highlighting that LLM outputs should be used with caution, ideally by adopting a stochastic view of their abilities. Overall, our findings suggest that, while ChatGPT could reduce some expert workload, its lack of consistency and domain understanding may limit its reliability for problem formulation tasks.

Materials design is an important component of modern science and technology, yet traditional approaches rely heavily on trial-and-error and can be inefficient. Computational techniques, enhanced by modern artificial intelligence (AI), have greatly accelerated the design of new materials. Among these approaches, inverse design has shown great promise in designing materials that meet specific property requirements. In this mini-review, we summarize key computational advancements for materials design over the past few decades. We follow the evolution of relevant materials design techniques, from high-throughput forward machine learning (ML) methods and evolutionary algorithms, to advanced AI strategies like reinforcement learning (RL) and deep generative models. We highlight the paradigm shift from conventional screening approaches to inverse generation driven by deep generative models. Finally, we discuss current challenges and future perspectives of materials inverse design. This review may serve as a brief guide to the approaches, progress, and outlook of designing future functional materials with technological relevance.

Face parsing is a fundamental task in computer vision, enabling applications such as identity verification, facial editing, and controllable image synthesis. However, existing face parsing models often lack fairness and robustness, leading to biased segmentation across demographic groups and errors under occlusions, noise, and domain shifts. These limitations affect downstream face synthesis, where segmentation biases can degrade generative model outputs. We propose a multi-objective learning framework that optimizes accuracy, fairness, and robustness in face parsing. Our approach introduces a homotopy-based loss function that dynamically adjusts the importance of these objectives during training. To evaluate its impact, we compare multi-objective and single-objective U-Net models in a GAN-based face synthesis pipeline (Pix2PixHD). Our results show that fairness-aware and robust segmentation improves photorealism and consistency in face generation. Additionally, we conduct preliminary experiments using ControlNet, a structured conditioning model for diffusion-based synthesis, to explore how segmentation quality influences guided image generation. Our findings demonstrate that multi-objective face parsing improves demographic consistency and robustness, leading to higher-quality GAN-based synthesis.

T he past century ha s witnessed incredible technological change . The many benefits and conveniences o f technology are accompanied by new complexities and human challenges that affect work, home, social, and civic realms. Th ere is a w idening gap "between a growing complexity of our own making and a lagging development of our own capacities" (Botkin et al., 1998) . Now, artificial intelligence promises to increase the rate of scientific discovery and innovation exponentially, creating new changes and p otential complexities to which humans must adapt (Friedman, 2017) . On the other hand, new AI tools, especially generative AI models, may help people to engage with the growing volume and complexity of information in their reasoning tasks such as decisionmaking and problem solving.

A United States federal judge has said that parts of Elon Musk's lawsuit against OpenAI to halt its conversion to a for-profit entity might go to trial, adding that the Tesla CEO will have to appear in court and testify. "Something is going to trial in this case," US District Judge Yvonne Gonzalez Rogers in Oakland, California, said early in the court session on Tuesday. "[Elon Musk will] sit on the stand, present it to a jury, and a jury will decide who is right." Rogers was considering Musk's recent request for a preliminary injunction to block OpenAI's conversion before going to trial, the latest move in a grudge match between the world's richest person and OpenAI CEO Sam Altman that is playing out publicly in court. The last time Rogers provided a preliminary injunction was in Epic Games's case against Apple in May 2021.
