Recent studies in reinforcement learning (RL) have made significant progress by leveraging function approximation to alleviate the sample complexity hurdle for better performance. Despite the success, existing provably efficient algorithms typically rely on the accessibility of immediate feedback upon taking actions. The failure to account for the impact of delay in observations can significantly degrade the performance of real-world systems due to the regret blow-up. In this work, we tackle the challenge of delayed feedback in RL with linear function approximation by employing posterior sampling, which has been shown to empirically outperform the popular UCB algorithms in a wide range of regimes. We first introduce Delayed-PSVI, an optimistic value-based algorithm that effectively explores the value function space via noise perturbation with posterior sampling.

Tech platforms would have to remove intimate images which have been shared without consent within 48 hours, under a proposed UK law. The government said tackling intimate image abuse should be treated with the same severity as child sexual abuse material (CSAM) and terrorist content. Failure to abide by the rules could result in companies being fined up to 10% of their global sales or have their services blocked in the UK. Janaya Walker, interim director of the End Violence Against Women Coalition, said the welcome and powerful move... rightly places the responsibility on tech companies to act. The proposals are being made through an amendment to the Crime and Policing Bill, which is making its way through the House of Lords.

The prime minister, Keir Starmer, said the'burden of tackling abuse must no longer fall on victims' in an article written for the Guardian. The prime minister, Keir Starmer, said the'burden of tackling abuse must no longer fall on victims' in an article written for the Guardian. Tech firms must remove'revenge porn' in 48 hours or risk being blocked, says Starmer PM says measure, also applied to deepfake nudes, is needed owing to a'national emergency' of online misogyny Deepfake nudes and "revenge porn" must be removed from the internet within 48 hours or technology firms risk being blocked in the UK, Keir Starmer has said, calling it a "national emergency" that the government must confront. Companies could be fined millions or even blocked altogether if they allow the images to spread or be reposted after victims give notice. Amendments will be made to the crime and policing bill to also regulate AI chatbots such as X's Grok, which generated nonconsensual images of women in bikinis or in compromising positions until the government threatened action against Elon Musk's company .

Trump says UK's Starmer making'a big mistake' with Chagos Islands deal Donald Trump has criticised the United Kingdom's plan to hand over the Chagos Islands to Mauritius, a day after the United States Department of State gave its official approval of the deal. The US president said on Wednesday that Prime Minister Keir Starmer was "making a big mistake" in the agreement to return sovereignty of the archipelago to Mauritius, and lease back the island of Diego Garcia, which is home to a UK-US military base. The Indian Ocean archipelago became part of British territory in 1814, with the UK detaching it from Mauritius before it gained independence in the 1960s. It then worked with the US to force the islands' residents to leave, in order to build a military base on Diego Garcia, which it had leased to the US. Mauritius won its legal battle for sovereignty over the islands in 2019, and the International Court of Justice (ICJ) urged the UK to cede control.

This has been addressed in7 prior work [4, 3] by finetuning VLMs on a given corpus for a given task [5] and8 conducting zero-shot evaluations on a new corpus [7]. However, the mere use of an9 unseen corpus for evaluation does not imply it is OOD. Q1 What do the instances that comprise the dataset represent (e.g., documents, photos,24 people,countries)? Pleaseprovideadescription.26 (a) We provide 384k image-text pairs. Q3 Does the dataset contain all possible instances or is it a sample (not necessarily ran-36 dom) of instances from a larger set? If the dataset is a sample, then what is the larger37 set?
