Getting Started

# Load classifier and autoencoder
model = classifiers.FaceAttribute()
ae = autoencoders.Transformer(weights="celeba")

# Load image
input = torch.randn(1, 3, 1024, 1024)

# Defining Latent Shift module
attr = captum.attr.LatentShift(model, ae)

# Computes counterfactual for class 3.
output = attr.attribute(input, target=3)
