NHS England is hurriedly withdrawing all the software it has written from public view because of the perceived risk of hacking from cutting-edge artificial intelligence. Security experts say the move is unnecessary and counterproductive. Software produced by the National Health Service has previously been made open-source and listed on GitHub because it is created with public money. This allows other organisations to build upon it and make better services more cheaply without duplicating effort. But NHS England has issued new guidance to staff, which has been shared with, that demands existing and future software be pulled from public view and kept behind closed doors.

Things to Do in L.A. From left, Meghann Adams, Malia Cohen and Herb Morgan are running for state controller in the California primary election. California voters will choose who oversees the state's finances as incumbent Malia Cohen faces Republican Herb Morgan, a finance executive, and Meghann Adams, a school bus driver and Peace and Freedom Party member. Morgan proposes using blockchain and AI technology for real-time spending transparency, while Adams advocates corporate audits and redirecting billions toward education, housing and healthcare for working-class Californians. Cohen improved financial report timeliness but fell short on promised audits of homelessness programs, the DMV and Employment Development Department. The state's fiscal watchdog oversees the intake and outtake of public funds and audits departments across the state.

Trump's mass firing just dealt another blow to American science Ambitious research is on the chopping block following yet more cuts at the National Science Foundation. This past week delivered another gut punch for science in the US. This time, the target was the National Science Foundation--a federal agency that funds major research projects to the tune of around $9 billion. The foundation's efforts were overseen by a board of 22 prominent scientists. On Friday last week, they were all fired . The NSF has been without a director since April 2025, when former director Sethuraman Panchanathan stepped down in the wake of DOGE-led funding cuts and mass firings.

What are Russia's gains from the Iran war? 'We are not losers; we are winners' Russia has continued heavy attacks on Ukraine for the past 24 hours, with several coming overnight on Thursday and in the early hours of Friday. At least one person has been killed and several have been injured. A Russian drone attack overnight damaged port infrastructure in Ukraine's southern Odesa region and wounded two people in the Black Sea port city of Odesa, regional Governor Oleh Kiper said on Friday morning. Two high-rise residential buildings were damaged in the attack, which destroyed apartments and caused fires, Kiper wrote on the Telegram messaging app. "This night, Russia again massively attacked the civilian infrastructure of the Odesa region: two people were injured," he said.

What are Russia's gains from the Iran war? 'We are not losers; we are winners' What do Ukraine's robot soldiers mean for the future of warfare? In a scene reminiscent of a computer war game, three battle-fatigued soldiers, dressed in white snow camouflage, emerge from a war-torn alley with their hands raised above their heads. They crouch down, following the orders being blasted at them, fear and shock etched across their faces as they stare down the barrel of a machinegun mounted on a so-called ground robot. In April, Ukrainian President Volodymyr Zelenskyy said that, for the "first time in the history of this war, an enemy position was taken exclusively by unmanned platforms - ground systems and drones". "Ground robotic systems have already carried out more than 22,000 missions on the front in just three months," he wrote in a post on X, alongside images of green machines with tank tracks and weapons mounted on top.

Different from general assembly datasets, we treat assemblable features, such as holes, stud and USB female, as objects, to enable finer-grained assembly knowledge understanding.

Having defined and validated the pairwise feedback simulator and evaluations in AlpacaFarm, we569 now turn our attention to studying methods that learn from pairwise feedback on AlpacaFarm.570 Unfortunately, the lack of existing benchmarks for learning from pairwise feedback for instruction571 following means that there has not been any open study of these methods in the instruction-following572 setting. In the remainder of this section, we will introduce our reference methods, which fall into two575 categories based on whether they fit a surrogate reward model as part of the learning process.576 FeedME is a method proposed by OpenAI [45] that incorporates human feedback578 with supervised fine-tuning on model generations that are rated 7/7 by human labelers. We adapt579 this approach to the pairwise feedback setting and call this baseline binary FeedME. This approach580 fine-tunes the SFT model on the chosen response in each preference pair with supervised learning.581 Motivated by controllable generation through conditioning [27, 34,582 29, 21], we propose binary reward conditioning, a baseline method that fine-tunes the SFT model583 with the feedback data Dpairwise by conditioning instances with either a positive or negative control584 token. Specifically, for each instance (x,y0,y1,z) 2D pairwise, the string concatenation of instruction585 x and response yz denoted as [x,yz] is prepended with the positive token and used in supervised586 fine-tuning (similarly [x,y1 z]is prepended with the negative token). This process creates a modified587 demonstration dataset that is double the size of Dpairwise. At test time, we draw samples from the588 fine-tuned model conditioned on the positive token.589 A.2 Methods that optimize a surrogate reward function590 We now describe methods that incorporate feedback by first building a surrogate reward model with591 pairwise feedback data. To start, we describe the step of training the surrogate reward model.592 While this can be a powerful approach,596 we will see that it can also lead to over-optimization [19] where models learn to exploit the reward597 model rather than achieve high true reward. We now describe 4 methods that leverage the surrogate598 reward model.599
