combraintf skillA
combraintf is agent-read markdown (skill) from cuhk-aim-group/neurodiscovery: Use this model doc whenever the user wants to run Com-BrainTF (Community-aware Brain Transformer) for fMRI phenotype prediction. Com-BrainTF uses dense FC matrices with a two-level Transformer (per-community local + global) and DEC pooling. NeuroClaw auto-derives community partitions from atlas naming conventions (Yeo 7-net for Schaefer, lobe-based for AAL)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Com-BrainTF Model Doc ## Overview Com-BrainTF (Community-aware Brain Transformer) 是一种针对 fMRI 连接组的两级 Transformer。第一级对每个脑功能社区（如 Yeo 7-network）内的 ROI 独立做 self-attention，并为每个社区维护一个可学习的 CLS token；第二级把所有社区的 CLS + 全部 ROI 节点拼接，再过一个带 DEC 池化的 Transformer，最后展平进 FC head。 - Paper: Bannadabhavi et al., 2023, "Community-Aware Transformer for Autism Prediction in fMRI Connectome"，MICCAI - Official code: https://github.com/ubc-tea/Com-BrainTF - NeuroClaw reimplementation: `models/combraintf/`（去除 hydra/omegaconf 与硬编码 node_clus_map，改为运行时从 atlas 推导） - Primary input: dense FC 矩阵 [B, N, N] - Primary output: phenotype prediction + DEC assignment + per-level attention **Research use only.** --- ## NeuroClaw 实现要点 1. **去除 hydra/omegaconf**：原版用 hydra 配置 + DictConfig，NeuroClaw 改为纯 Python 构造函数，所有参数显式传入。 2. **动态 community partition**：原版从 `node_clus_map.pickle` 加载 Schaefer-400 的固定社区映射；NeuroClaw 在 `data_adapter.py::build_community_ids(atlas)` 里根据 ROI 名自动推导： - `schaefer_*_7net` → Yeo 7-network（Vis/SomMot/DorsAttn/SalVentAttn/Limbic/Cont/Default）+ Unknown 兜底，共 8 组 - `aal_*` / `destrieux` / `dk_*` / `harvard_oxford_*` → 7 lobe + Other = 8 组 …

How to install
mdr add cuhk-aim-group/neurodiscovery/combraintf@git:20260519.c62dcfbmdr add cuhk-aim-group/neurodiscovery/combraintf@sha256:d71e1fc10bd56349Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
