The results reveal that while LLMs, such as GPT-2, Gemma, Llama 2, and others, exhibit hierarchical syntactic processing and alignment with left-hemisphere brain activity, the mechanisms underlying their representations diverge significantly from those in human cortical regions. Notably, newer models like Gemma 2 demonstrate improved alignment, whereas others, such as Llama 3.1, show weaker human-model correlations despite enhanced task performance.\u300d\u3068\u306e\u3053\u3068\u3002\u8133\u3068\u306e\u985e\u4f3c\u6027\u304c\u672c\u5f53\u306b\u3042\u308b\u306e\u304b\uff08\u305d\u308c\u304c\u5224\u65ad\u53ef\u80fd\u306a\u30ec\u30d9\u30eb\u3067\u60c5\u5831\u53d6\u5f97\uff06\u5206\u6790\u3067\u304d\u308b\u306e\u304b\uff09\u306a\u3069\u7591\u554f\u70b9\u306f\u3042\u308b\u3082\u306e\u306e\u3001\u9762\u767d\u3044\u7814\u7a76\u3002<\/li>\n\n\n\n<li>\u30ea\u30dd\u30b8\u30c8\u30ea\u306f<a href=\"https:\/\/github.com\/LilTiger\/HFTP\">GitHub &#8211; LilTiger\/HFTP: Hierarchical Frequency Tagging Probe (HFTP): A Unified Approach to Investigate Syntactic Structure Representations in Large Language Models and the Human Brain<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[223,706],"class_list":["post-7637","post","type-post","status-publish","format-standard","hentry","category-arxiv","tag-llm","tag-706"],"_links":{"self":[{"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/7637","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=7637"}],"version-history":[{"count":2,"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/7637\/revisions"}],"predecessor-version":[{"id":7639,"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/7637\/revisions\/7639"}],"wp:attachment":[{"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7637"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=7637"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/devneko.jp\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=7637"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
