I'm very excited to share our new mathematical framework for consciousness! co-authored with Masafumi Oizumi and Chanseok Lim. We use principal bundle geometry to characterize the structure of qualia. I hope to find likeminded people to explore this new frontier.

思い入れのあるクオリアと対称性に関する理論論文のプレプリントです。大泉さんと林さんとの共著です。以前からequivarianceでクオリアを特徴づけることを考えて来た中で、大泉さんが主束の話に繋いだことでクオリア構造を数理的に理解する深い話になりました。会心の一撃なので是非読んでください。

論文をnotebooklmに突っ込んだら、非常にわかりやすいポッドキャストを作ってくれた。論文自体は難しい数学も使っているので、概要を知りたい人は、是非これを聞いて欲しい(11分)。 dropbox.com/scl/fi/stdftxc…

Masafumi Oizumi The math may be inaccessible to some. Here's a podcast generated by NotebookLM explaining the gist of this paper in simple language. dropbox.com/scl/fi/ncj3njt…

Ryota Kanai will present our recent preprint at the Models of Consciousness conference. If you're attending, don't miss it! Here is the latest version of our preprint, which has been updated slightly to improve readability. osf.io/preprints/psya…

Can AI grasp the complex web of human emotions? Our paper w/ H.Asanuma, Naoko Koide-Majima, Ken Nakamura, Takato Horii, Shinji Nishimoto tests if LLMs can accurately infer the relational structure of emotions from watching movies. Check out Haruka's thread for a summary!👇

M2の前川くんの論文がarXivに上がりました。情報熱力学の最新版の結果です。情報流を時間変化を引き起こす過剰情報流と時間変化しない維持情報流に分解して、それぞれに対し情報熱力学を構築する話です。理研吉村さんやD2永山くんが開発してきた最適輸送手法に基づいてます。 arxiv.org/abs/2509.21985

大泉研の関澤さんの結果がarXivに出ました。 arxiv.org/pdf/2510.21340 維持エントロピー生成率を振動数ごとに(Koopman modeで)分解する話で、前回のPRXの結果の一般化になっています。特に非線形振動+ノイズのランジュバン系において、振動寄与がどう散逸に影響を与えるかを議論できます。

Thrilled to share our latest preprint with D. Sekizawa and Sosuke Ito (伊藤 創祐)! arxiv.org/abs/2510.21340 We merge Koopman operator analysis with stochastic thermodynamics to uncover the oscillatory origins of thermodynamic dissipation in nonlinear systems. This framework pinpoints

Our new paper with Soh Takahashi, Masaru Sasaki, Ken Takeda is out in Neural Networks! We investigated which AI learning mechanisms generate representational structures of natural objects that are similar to humans'. Using the THINGS dataset (1854 objects), we found CLIP models
