Machine Learning Frontier Project

Method Chosen

五个数据集包括一共可分为两类:

  • 时间序列数据 $$({\mathbf{x}^{(1)}_ {t}} _ {t=1}^T,\cdots,{\mathbf{x}^{(N)}_ {t}} _ {t=1}^T)\in \mathbb{R}^{N\times m\times T},\mathbf{x}_{t}^{(i)}\in\mathbb{R}^m$$
  • 非时间序列数据 $(\mathbf{x}^{(1)},\cdots,\mathbf{x}^{(N)})\in \mathbb{R}^{N\times m}$

Description of Datasets

一共是如下的五个数据集, 中括号内为该数据集中所包含的所有标签.

1. ADNI: ['AD', 'MCI', 'MCIn', 'MCIp', 'NC']

$N=51+99+56+43+52,m=186$.

2. ADNI_90_120_fMRI:['AD', 'EMCI', 'LMCI', 'NC']

$N=59+56+43+48,m=90,T=120$.

3. FTD_90_200_fMRI:['FTD', 'NC']

$N=95+86,m=90,T=200$.

4. OCD_90_200_fMRI:['NC', 'OCD']

$N=95+86,m=90,T=200$.

5. PPMI:['NC', 'PD']

$N=169+374,m=294$.

Meaning of Datasets and Labels

Datasets

ADNI:与认知功能有关的神经退行性疾病.

FTD:前额颞叶退行性病变.

OCD:强迫症障碍病.

PPMI:帕金森性疾病.

Labels

AD:阿尔茨海默病;

MCI:轻度认知功能障碍;

MCIn:某些患有MCI的个体在一段时间内未表现出认知功能的明显恶化;

MCIp:某些患有MCI的个体在一段时间内经历了认知功能的明显恶化;

NC:正常对照组,这是一组没有明显认知功能问题的健康个体;

EMCI:早期阶段被诊断为轻度认知功能障碍的个体;

LMCI:晚期轻度认知功能障碍,这些个体的认知功能问题可能已经更加明显,并可能是认知障碍的前兆;

FTD:前额颞叶退行性病变;

OCD:表示强迫症障碍;

PD:表示帕金森病.

数据集里不同维度解释

  1.  ADNI: (e.g., AD的shape为(51, 186):51表示样本数,186表示特征维度).
    
  2.  ADNI_90_120_fMRI: (e.g., AD的shape为(59, 90, 120):59表示样本数,90表示脑区数,120表示时间序列).
    
  3.  FTD_90_200_fMRI: (e.g., NC的shape为(86, 90, 200):86表示样本数,90表示脑区数,200表示时间序列).
    
  4.  OCD_90_200_fMRI: (e.g., NC的shape为(20, 90, 200):20表示样本数,90表示脑区数,200表示时间序列).
    
  5.  PPMI: (e.g., PD的shape为(374, 294):374表示样本数,294表示特征维度).
