卡迪夫大学新研究：AI 尚无法像人类教师一样可靠地批改作业_我的网站

A |     Finland's Prime Minister Sanna Marin landed in hot water after several short videos of her partying with friends were leaked online. Marin later confirmed the authenticity of the footage.,In the videos, the prime minister is seen at a private apartment alongside influencers, TV and radio hosts, and a member of parliament - Ilmari Nurminen. Marin is seen singing, dancing and hugging her friends.,However, journalists from Finnish newspaper Iltalehti claim to have heard Marin’s friends using the words "flour gang" in one of the videos, alleging referring to cocaine. Several lawmakers, including Riikka Purra, chair of the Finns Party, and Mikko Kärnä, member of the Centre Party, have harshly criticized Marin's behavior and demanded that she undergo a drug test.,"The people are also allowed to expect this from their prime minister," Kärnä wrote in his Twitter account.,The 36-year-old prime minister confirmed that the party took place, noting that it happened a "couple of weeks ago,” but expressed doubt that her friends shouted "flour gang.”,Marin also denied taking any drugs or even consuming alcohol in large volumes. However, she said that she did not mind sitting a drug test.,"I have danced, sung, celebrated, done legal things. I have nothing to hide. I haven't used any drugs, so it's not a problem to take a drug test, but I also think it's quite special that something like this is required. I didn't see any evidence that anything was used anywhere," the prime minister said.,Netizens' reactions were mixed in light of the leaked videos. While some were shocked or disgruntled by the behavior not typically seen in top politicians, others suggested that Marin might have won voters’ hearts by showing her human side.,Finland's PM Parties at Nightclub Until 4 AM After Contact With COVID-Positive Official6 December 2021, 16:37 GMT,This was not the first time that the Finnish prime minister has been caught partying with friends. In December 2021 during a coronavirus infections surge, she was slammed for partying a day after a member of her government tested positive for COVID-19.。     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。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。

B | 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。
