Recommendation systems and assistants (from now on, recommenders) - algorithms suggesting items or providing solutions based on users' preferences or requests [99, 105, 141, 166] - influence through online platforms most actions of our day to day life. For example, recommendations on social media suggest new social connections, those on online retail platforms guide users' product choices, navigation services offer routes to desired destinations, and generative AI platforms produce content based on users' requests. Unlike other AI tools, such as medical diagnostic support systems, robotic vision systems, or autonomous driving, which assist in specific tasks or functions, recommenders are ubiquitous in online platforms, shaping our decisions and interactions instantly and profoundly. The influence recommenders exert on users' behaviour may generate long-lasting and often unintended effects on human-AI ecosystems [131], such as amplifying political radicalisation processes [82], increasing CO2 emissions in the environment [36] and amplifying inequality, biases and discriminations [120]. The interaction between humans and recommenders has been examined in various fields using different nomenclatures, research methods and datasets, often producing incongruent findings.

Given the growing influx of misinformation across news and social media, there is a critical need for systems that can provide effective real-time verification of news claims. Large language or multimodal model based verification has been proposed to scale up online policing mechanisms for mitigating spread of false and harmful content. While these can potentially reduce burden on human fact-checkers, such efforts may be hampered by foundation model training data becoming outdated. In this work, we test the limits of improving foundation model performance without continual updating through an initial study of knowledge transfer using either existing intra- and inter- domain benchmarks or explanations generated from large language models (LLMs). We evaluate on 12 public benchmarks for fact-checking and misinformation detection as well as two other tasks relevant to content moderation -- toxicity and stance detection. Our results on two recent multi-modal fact-checking benchmarks, Mocheg and Fakeddit, indicate that knowledge transfer strategies can improve Fakeddit performance over the state-of-the-art by up to 1.7% and Mocheg performance by up to 2.9%.

We present RICHES, a novel approach that interleaves retrieval with sequence generation tasks. RICHES offers an alternative to conventional RAG systems by eliminating the need for separate retriever and generator. It retrieves documents by directly decoding their contents, constrained on the corpus. Unifying retrieval with generation allows us to adapt to diverse new tasks via prompting alone. RICHES can work with any Instruction-tuned model, without additional training. It provides attributed evidence, supports multi-hop retrievals and interleaves thoughts to plan on what to retrieve next, all within a single decoding pass of the LLM. We demonstrate the strong performance of RICHES across ODQA tasks including attributed and multi-hop QA.

We argue that the selective inclusion of data points based on latent objectives is common in practical situations, such as music sequences. Since this selection process often distorts statistical analysis, previous work primarily views it as a bias to be corrected and proposes various methods to mitigate its effect. However, while controlling this bias is crucial, selection also offers an opportunity to provide a deeper insight into the hidden generation process, as it is a fundamental mechanism underlying what we observe. In particular, overlooking selection in sequential data can lead to an incomplete or overcomplicated inductive bias in modeling, such as assuming a universal autoregressive structure for all dependencies. Therefore, rather than merely viewing it as a bias, we explore the causal structure of selection in sequential data to delve deeper into the complete causal process. Specifically, we show that selection structure is identifiable without any parametric assumptions or interventional experiments. Moreover, even in cases where selection variables coexist with latent confounders, we still establish the nonparametric identifiability under appropriate structural conditions. Meanwhile, we also propose a provably correct algorithm to detect and identify selection structures as well as other types of dependencies. The framework has been validated empirically on both synthetic data and real-world music.

Data Shapley provides a principled framework for attributing data's contribution within machine learning contexts. However, existing approaches require re-training models on different data subsets, which is computationally intensive, foreclosing their application to large-scale models. Furthermore, they produce the same attribution score for any models produced by running the learning algorithm, meaning they cannot perform targeted attribution towards a specific model obtained from a single run of the algorithm. This paper introduces In-Run Data Shapley, which addresses these limitations by offering scalable data attribution for a target model of interest. In its most efficient implementation, our technique incurs negligible additional runtime compared to standard model training. This dramatic efficiency improvement makes it possible to perform data attribution for the foundation model pretraining stage for the first time. We present several case studies that offer fresh insights into pretraining data's contribution and discuss their implications for copyright in generative AI and pretraining data curation.

Former'Bachelorette' lead Hannah Brown spoke with Fox News Digital ahead of publication day for her first novel, 'Mistakes We Never Made.' Brown shared insight on the storyline, writing process and how her confidence grew in the process. The world of dating is hard to navigate -- even if you're an A-list celebrity. Celebrities have taken a wide range of approaches to finding their person. Many have had high-profile relationships with fellow stars, while others have dated outside the spotlight and have kept their love life a lot more private. Some celebrities have even found success using dating apps.

Devindra: because like you could just always just take a photo of something and be like, yeah, that's how we wonder if it's going to Cherlynn: be a ram hog.

Samsung's latest Unpacked event will kick off on July 10th. The company has already released its latest flagship phones this year, unveiling the S24 family. The tiny wearable is slated to arrive "in or around August," so it would be more of a surprise if the device didn't appear at Unpacked. The ring will measure heart rate, movement and breathing to help track your sleep. I'm expecting the Galaxy Z Fold 6 and Galaxy Z Flip 6 to appear, although with minor tweaks that might not warrant an upgrade from last year's foldables.

Jesus is punching the devil on Facebook. The two are in a boxing ring. Jesus is wearing a pair of white boxing shorts with his name embroidered on the waistband. He is ripped beyond belief; not only does he have six-pack abs, but every muscle on his body is bulging. Jesus is hitting the devil directly on the chin, a knockout blow.

The Center for Investigative Reporting (CIR), which publishes Mother Jones and Reveal, said on Thursday that it had filed the lawsuit accusing the tech firms of using its content without permission in a "rebuke to artificial intelligence and its exploitative practices". "OpenAI and Microsoft started vacuuming up our stories to make their product more powerful, but they never asked for permission or offered compensation, unlike other organisations that license our material," Monika Bauerlein, CEO of the Center for Investigative Reporting, said in a statement. The work of journalists, at CIR and everywhere, is valuable, and OpenAI and Microsoft know it." OpenAI and Microsoft did not immediately respond to requests for comment. OpenAI's ChatGPT chatbot relies on vast quantities of information scraped from the internet, including news sites, to respond to users' queries.
