IRS Backtracks, Edits Job Posting Seeking Agents Willing to 'Use Deadly Force' After Online Outrage_我的网站

一 |      8 月 24 日消息，据外媒 Phys.org 今天（24 日）报道，卡迪夫大学和墨尔本大学的一项新研究发现，生成式人工智能（GenAI）目前还无法像人类教师一样可靠地评判学生的书面作业。    The IRS deleted a job listing seeking “new special agents” who are “willing to use deadly force, if necessary” from their website, following a fierce backlash on social media Wednesday–only to reupload it within a day with the offending portion removed.,The IRS has removed the line "Carry a firearm and be willing to use deadly force, if necessary" from their IRS Criminal Investigation Special Agent listing following the fiasco yesterday.Archived here: https://t.co/vBy6lB841RActive link: https://t.co/uvwbrAkIit pic.twitter.com/vNmcSXuD7w— Ford Fischer (@FordFischer) August 11, 2022,Per the now-updated page on the IRS website, “IRS Special Agents are considered the premier financial investigators for the Federal government.”,“Special Agents are duly sworn law enforcement officers who are trained to ‘follow the money,’” the listing says, warning that “no matter what the source, all income earned, both legal and illegal, has the potential of becoming involved in crimes which fall within the investigative jurisdiction of the IRS Criminal Investigation.”,The posting sparked a wave of condemnation from ordinary citizens and influential politicians alike, including Sen. Ted Cruz (R-TX), who took to Twitter to express his opposition to the proposed new IRS jobs:,“HELL NO. Every Republican should pledge we WILL NOT FUND these 87k armed new IRS agents who will target the American people.”,HELL NO.Every Republican should pledge we WILL NOT FUND these 87k armed new IRS agents who will target the American people. https://t.co/BmKZVjVdNx— Ted Cruz (@tedcruz) August 10, 2022,Funding for the special agents in question is likely to be drawn from a huge budget boost the IRS anticipates, with Democrats in the House set to approve the so-called “Inflation Reduction Act.”,Along with around $430 billion the Biden administration says will address climate change and extend Affordable Care Act subsidies, the new spending bill promises to pump $80 billion into the IRS over the next ten years - more than doubling the size of the agency with over 87,000 new positions. According to the now-updated job listing, many of them will be armed; one of the “key requirements” is that applicants “be legally allowed to carry a firearm.”,The ad in question was first noticed by documentarian Ford Fischer, who pointed out in a subsequent post on Twitter that, by June, the criminal division of the IRS had spent more on ammunition in the previous three months than they typically spent in an entire year in the recent past.,Fischer told Sputnik News he finds it “fascinating” that “following the attention [he] brought to this job listing, the page went down for a while, and now with it back online, the ‘willingness to engage in deadly force' line has been removed.”,“The reality is that while perhaps finding some renewed relevance in today's news cycle about the IRS, this listing isn't particularly unusual,” Fischer notes. “The agency has been spending more than $600,000 annually on ammunition, which has been charted out for at least the past three administrations.”,“What's new is that while the left (to be clear, I mean real leftists - not Democrats) have been fairly adamant in their opposition to law enforcement at all levels, the Republicans seem to find opposition when the politics line up. For example, they currently are deeply critical of the FBI, and IRS.”,Opposition to the spending bill authorizing the IRS expansion has come almost entirely from the GOP. A recent analysis by House Republicans found that 60% of new audits expected to be unleashed by the doubling in IRS personnel will fall on those making $75,000 or less a year. But Democrats claim those making less than $400,000 will not be targeted by the new IRS agents.,The IRS reportedly did not respond to inquiries by Fox News or the National Review about its removal of the job posting.。研究人员使用 ChatGPT 的两个版本，对 50 篇生物科学专业本科生论文进行评分，以测试大模型评估学生作业的能力。ChatGPT 需要按照 7 项标准批改这些论文，研究人员还采用了 4 种不同的提示方式，随后将大模型与人工评分的平均分和分数波动情况进行比较。图源：Pexels卡迪夫大学生物科学学院威廉 · 凯博士指出：“研究结果显示，模型给出的分数波动很大，无法准确预测人工评分。生成式 AI 与人类批改同一批论文时存在明显差异。只看论文总分，两者给出的结果相对接近；一旦具体到每项评分标准和每一篇论文，大模型与人工评分之间的差距就相当明显。”除一种情况外，AI 模型给出的平均分普遍高于人工评分。平均分方面，AI 模型与人工评分的最大差距达到 16.1 分；具体到单篇论文，最大差距达到 40 分。获悉，威廉 · 凯还发现，AI 往往会压低高分论文的成绩，又把低分作业的成绩抬高，最终使分数系统性地向中间集中。研究结果说明，至少现阶段，即使经过大量训练，AI 仍无法可靠地对主观性较强的书面作业给出与人类相当的分数。“我们测试的大模型目前并不适合取代教师，为学生预测作业成绩。”研究人员指出，高等教育领域确实很关注大模型能否利用模式识别能力，让学生作业评分更加客观，同时提高批改效率、减轻教职人员压力。但这项研究表明，目前并不适合这么做。此外，未经学生明确同意便把作业提交给 AI 工具，本身还涉及伦理问题；大模型也不能、也不应该被依赖来给学生的长篇书面作业评分。“随着大模型继续发展，未来模仿人类判断的能力可能会提高。但从这项研究来看，要让 AI 给出的分数与人工评分真正保持一致，恐怕并不容易。
