condo-adapter

ConDo Adapter performs Confounded Domain Adaptation, which corrects for batch effects while conditioning on confounding variables. We hope it sparks joy as you clean up your data!

Installation

After cloning this repo, install the dependencies on the command-line via:

pip install -r requirements.txt

In this directory, run

pip install -e .

Usage

Import ConDo and create the adapter:

import condo
condoer = condo.ConDoAdapter()

Try using it:

import numpy as np
X_T = np.sort(np.random.uniform(0, 8, size=(100, 1)))
X_S = np.sort(np.random.uniform(4, 8, size=(100, 1)))
Y_T = np.random.normal(4 * X_T + 1, 1 * X_T + 1)
Y_Strue = np.random.normal(4 * X_S + 1, 1 * X_S + 1)
Y_S = 5 * Y_Strue + 2
condoer.fit(Y_S, Y_T, X_S, X_T)
Y_S2T = condoer.transform(Y_S)
print(f"before ConDo: {np.mean((Y_S - Y_Strue) ** 2):.3f}")
print(f"after ConDo:  {np.mean((Y_S2T - Y_Strue) ** 2):.3f}")
