So happy to see Taguchi-san’s paper published! I had the pleasure of closely guiding this work — it’s been incredibly rewarding to watch it take shape over time. A real testament to his perseverance and dedication — well done! For more details, check out the thread under his

Our paper is out in #JNeurosci! T.Taguchi Jun Kitazono Shuntaro Sasai (笹井俊太朗) Bidirectional signaling (feedforward and feedback loops) is ubiquitous in the brain and considered fundamental to brain function—but where exactly in the brain do these strong bidirectional networks emerge, and

Info theory offers powerful measures for capturing complexity & interaction among elements of a complex system, like the brain! 🧠 Here's our new unified reference for key info-theoretic time series measures ft. 📊 visuals, ➗equations, & 💬descriptions: arxiv.org/abs/2505.13080

アーカイブ出ました〜〜！！ マルチモーダルLLMが人間の感情構造をどの程度推定できているか検証した論文です、もしよければぜひ読んでみてください〜〜！ arxiv.org/abs/2505.12746

Our latest preprint! H.A Takato Horii Shinji Nishimoto arxiv.org/abs/2505.12746 We investigated to what extent Multimodal LLMs replicate human high-dimensional emotion structures using unsupervised alignment. MLLMs achieve unprecedented accuracy at capturing emotion

Excited to share our new paper in iScience! 🎉 cell.com/iscience/fullt… We present an unsupervised alignment framework applied to neural recordings, enabling comparison of neural representations across individuals and brain areas—without relying on stimulus correspondence.

Excited to share another new paper in Journal of Neuroscience Methods! We introduce GWTune, a toolbox for unsupervised alignment using Gromov–Wasserstein Optimal Transport (GWOT). Open-source and ready to use. 🔗 doi.org/10.1016/j.jneu… 🧰 oizumi-lab.github.io/GWTune/

大学院での研究のプレプリントを公開しました！ 様々な学習方法で訓練された DNN が、どの程度の細かさで人間と一致するオブジェクト表現を学習しているのかを、unsupervised alignment という手法で調べた研究です よかったら覗いてみてください 👇 arxiv.org/abs/2505.16419

新しいプレリントを公開しました： biorxiv.org/content/10.110… 音声とテキストが同時に与えられた時、選択的注意を向けた刺激の意味情報の方が、脳活動によるデコーディング精度が高くなります。

アラヤの笹井さん率いるチームからInterspeech2025に採択された論文をNotebookLMに解説してもらったら、とっても理解しやすかったのでぜひ聞いてみてください。 doi.org/10.48550/arXiv… 脳波と筋電図を使って、声を出さない「サイレントスピーチ」を実現する研究です。 youtube.com/watch?v=oPD6AY…

Excited to share our new preprint! "Principal bundle geometry of qualia: Understanding the quality of consciousness from symmetry", co-first-authored with Ryota Kanai Ryota Kanai 🌙 and co-authored with Chanseok Lim. osf.io/agupq_v2 We propose that the relational structure
