NoteSample Methods Perspective

This page is illustrative sample content. It does not claim that a particular model, dataset, or analysis has been validated by FengLab.

Begin with the scientific task

A future methods perspective might separate three different goals:

  1. Description: representing complex immune measurements in a useful space;
  2. Prediction: estimating an outcome \(y_i\) for a perturbation \(x\); and
  3. Design: identifying which observations or interventions would be most informative.

Keeping these goals distinct can make evaluation more meaningful. A model that compresses data well is not automatically a reliable predictor, and a predictive model is not automatically suitable for intervention design.

Questions for responsible use

  • What biological variation is present in the training data?
  • Which individuals or contexts are poorly represented?
  • Does performance persist across cohorts, time points, and measurement platforms?
  • Can uncertainty be communicated at the level of an individual prediction?
  • Which conclusions depend on the model, and which are supported directly by data?

What a real post should include

A completed Insight should name the method or dataset under discussion, distinguish evidence from hypothesis, link to code or data where appropriate, and state the limits of the analysis.
