用途:
|
||||
- 从一个文件夹中自动读取第一个 .mat EEG 文件(64通道或32通道)
|
||||
- 若为64通道,则按 idx64_to_32 映射选出32通道
|
||||
- 提取切片特征(DE + PSD(var近似),不含Asym)
|
||||
- 加载你训练好的 .pth 模型(FusionNet结构)
|
||||
- 输出该受试者的 HC / MDD 判断结果
|
||||
|
||||
运行方式(命令行):
|
||||
python infer_pth_from64_to32.py --eeg_dir "D:\\xxx\\folder" --model_path "C:\\xxx\\model.pth"
|
||||
|
||||
也可在其他py里import:
|

from infer_pth_from64_to32 import predict_hc_mdd
|

res = predict_hc_mdd(eeg_dir, model_path)
