ODE

Neural ODE Neural Ordinary Differential Equations NeurIPS 2018 | YouTube

  • consider NN not as discrete layers but as a continuous function, a whole big block
  • not specifying depth of the network, let it learn by itself
  • better than RNN because: 1. more efficient 2. better at irregular time series
  • add ODE solver in the forward propagation

Integrating Expert ODEs into Neural ODEs: Pharmacology and Disease Progression NeurIPS 2021 | code

  • combine (explainable but limited) expert knowledge with ML latent representative power

COX-based

Cox Survival model Youtube

  • combination of Kaplan miler and exponential model
  • assume that hazard changes over time, but hazard ratio is proportional
  • can only estimate hazard ratio of factors, cannot predict survival itself

Optimizing Survival Analysis of XGBoost for Ties to Predict Disease Progression of Breast Cancer

  • method: EXSA XGBoost + Cox, based on selected features
  • data: 12119 breast cancer patients
  • task: risk score, grouping

LSTM

ATTAIN: Attention-based Time-Aware LSTM Networks for Disease Progression Modeling

  • 结合了之前分开有用过的attention和time-aware, added time interval to the attention

SSL-based

Longitudinal self-supervised learning

  • dataset: neuroimaging of Alzheimer (2641 of 811 patients) and alcohol dependence (1499 of 274+329)
  • Factor disentanglement: one dimension can be explained by a specific factor (brain age), invariant to other factors (e.g. gender, ethnicity)`

Modeling Disease Progression In Retinal OCTs With Longitudinal Self-Supervised Learning 19年一个workshop

  • dataset: 3308 scans from 221 patients
  • pretext task: predict the time interval between two scan images of the same patient
  • transfer task: intermediate state -> advanced stage ? by adding a classifier and fine-tune

Self-Supervised Pretraining and Transfer Learning Enable Flu and COVID-19 Predictions in Small Mobile Sensing Datasets Conference on Health, Inference, and Learning (CHIL) 2023 | code data on request

  • dataset: Homekit Flu Monitoring Study: 591k user-days of Fitbit data, 5196 participants, 6 months
  • pretext task: same user, reconstruct data, predict Domain Inspired Features (best!)
  • transfer task: infer positive / symptoms
