Broadly accessible generative AI models like Dall-E have made it possible for anyone to create compelling visual art. In online communities, the introduction of AI-generated content (AIGC) may impact community dynamics by shifting the kinds of content being posted or the responses to content suspected of being generated by AI. We take steps towards examining the potential impact of AIGC on art-related communities on Reddit. We distinguish between communities that disallow AI content and those without a direct policy. We look at image-based posts made to these communities that are transparently created by AI, or comments in these communities that suspect authors of using generative AI. We find that AI posts (and accusations) have played a very small part in these communities through the end of 2023, accounting for fewer than 0.2% of the image-based posts. Even as the absolute number of author-labelled AI posts dwindles over time, accusations of AI use remain more persistent. We show that AI content is more readily used by newcomers and may help increase participation if it aligns with community rules. However, the tone of comments suspecting AI use by others have become more negative over time, especially in communities that do not have explicit rules about AI. Overall, the results show the changing norms and interactions around AIGC in online communities designated for creativity.

During remote communication, participants often share both digital and physical content, such as product designs, digital assets, and environments, to enhance mutual understanding. Recent advances in augmented communication have facilitated users to swiftly create and share digital 2D copies of physical objects from video feeds into a shared space. However, conventional 2D representations of digital objects restricts users' ability to spatially reference items in a shared immersive environment. To address this, we propose Thing2Reality, an Extended Reality (XR) communication platform that enhances spontaneous discussions of both digital and physical items during remote sessions. With Thing2Reality, users can quickly materialize ideas or physical objects in immersive environments and share them as conditioned multiview renderings or 3D Gaussians. Thing2Reality enables users to interact with remote objects or discuss concepts in a collaborative manner. Our user study revealed that the ability to interact with and manipulate 3D representations of objects significantly enhances the efficiency of discussions, with the potential to augment discussion of 2D artifacts.

Multi-hop reasoning, which requires multi-step reasoning based on the supporting documents within a given context, remains challenging for large language models (LLMs). LLMs often struggle to filter out irrelevant documents within the context, and their performance is sensitive to the position of supporting documents within that context. In this paper, we identify an additional challenge: LLMs' performance is also sensitive to the order in which the supporting documents are presented. We refer to this as the misordered context problem. To address this issue, we propose a simple yet effective method called context repetition (CoRe), which involves prompting the model by repeatedly presenting the context to ensure the supporting documents are presented in the optimal order for the model. Using CoRe, we improve the F1 score by up to 30%p on multi-hop QA tasks and increase accuracy by up to 70%p on a synthetic task. Additionally, CoRe helps mitigate the well-known "lost-in-the-middle" problem in LLMs and can be effectively combined with retrieval-based approaches utilizing Chain-of-Thought (CoT) reasoning.

Adaptation methods are developed to adapt depth foundation models to endoscopic depth estimation recently. However, such approaches typically under-perform training since they limit the parameter search to a low-rank subspace and alter the training dynamics. Therefore, we propose a full-parameter and parameter-efficient learning framework for endoscopic depth estimation. At the first stage, the subspace of attention, convolution and multi-layer perception are adapted simultaneously within different sub-spaces. At the second stage, a memory-efficient optimization is proposed for subspace composition and the performance is further improved in the united sub-space. Initial experiments on the SCARED [1] dataset demonstrate that results at the first stage improves the performance from 10.2% to 4.1% for Sq Rel, Abs Rel, RMSE and RMSE log [3, 13, 15, 16] in the comparison with the state-of-the-art models.

Artificial intelligence is expected to have an impact on the upcoming US election in November. States have been trying to protect against misinformation by passing laws that require political advertisements to disclose when they have used generative AI. Twenty states now have rules on the books, and according to new research, voters have a negative reaction to seeing those disclaimers. That seems like a pretty fair response: If a politician uses generative AI to mislead voters, then voters don't appreciate that. The study was conducted by New York University's Center on Technology Policy and first reported by The Washington Post.

Hearst has become the latest major US publisher to sign an agreement to license its content to ChatGPT creator OpenAI. As part of a partnership announced on Tuesday, content from more than 60 Hearst-owned publications will appear in ChatGPT and other OpenAI products. Some of the publisher's more notable properties include Esquire, Cosmopolitan and Elle. It also owns newspapers like the San Francisco Chronicle. When Hearst content appears in ChatGPT, the software will provide citations and direct links.

Roli is no stranger to quirky musical instruments. After all, it pioneered the idea of a "squishy" MIDI controller. The company's latest tool, however, could be its weirdest. The Roli Airwave is an AI-infused piano teaching gadget that also doubles as a digital theremin. Yes, the same high-pitched theremin that has appeared on hit records like The Beach Boys' "Good Vibrations" and Erykah Badu's "Incense." The Airwave is basically a tall stand with a camera on top.

The paper shows the importance of the used training setup for MAML and RL 2. A setup can include "exploratory episodes" and measure the loss only on the next "reporting" episodes. The paper presents interesting results. The introduced E-MAML and E-RL 2 variants clearly help. The main problem with the paper: The paper does not define well the objective. I only deduced from the Appendix C that the setup is: After starting in a new environment, do 3 exploratory episodes and report the collected reward on the next 2 episodes.

This paper studies a distributed multi-armed bandits setting, where every round each of N players must choose one of K arms. If a player picks the same arm as some other player, they receive payoff zero; otherwise, they receive payoff drawn from some distribution (specific to that player and that arm). This can be thought of as learning a distributed allocation or matching from players to arms. The goal is to design a communication-free learning algorithm that maximizes the total overall utility of all the players (or alternatively, minimizes their regret with respect to the best fixed allocation). The authors design an algorithm which receives total regret of O(log 2 T).

Multi-modal Entity Linking (MEL) is a fundamental component for various downstream tasks. However, existing MEL datasets suffer from small scale, scarcity of topic types and limited coverage of tasks, making them incapable of effectively enhancing the entity linking capabilities of multi-modal models. To address these obstacles, we propose a dataset construction pipeline and publish $M^3EL$, a large-scale dataset for MEL. $M^3EL$ includes 79,625 instances, covering 9 diverse multi-modal tasks, and 5 different topics. In addition, to further improve the model's adaptability to multi-modal tasks, We propose a modality-augmented training strategy. Utilizing $M^3EL$ as a corpus, train the $\textit{CLIP}_{\textit{ND}}$ model based on $\textit{CLIP} (\textit{ViT}-\textit{B}-\textit{32})$, and conduct a comparative analysis with an existing multi-modal baselines. Experimental results show that the existing models perform far below expectations (ACC of 49.4%-75.8%), After analysis, it was obtained that small dataset sizes, insufficient modality task coverage, and limited topic diversity resulted in poor generalisation of multi-modal models. Our dataset effectively addresses these issues, and the $\textit{CLIP}_{\textit{ND}}$ model fine-tuned with $M^3EL$ shows a significant improvement in accuracy, with an average improvement of 9.3% to 25% across various tasks. Our dataset is available at https://anonymous.4open.science/r/M3EL.
