Alice4Alice: ALICE algorithms for painting the cartoon of Alice's Adventures in Wonderland

Four variants of ALICE on toy datasets

In unsupervised learning case:

• (a) Explicit cycle-consistency (ALICE_l2.py)
• (b) Implicit cycle-consistency (ALICE_A.py)

In weakly-supervised learning case:

• (c) Explicit mapping (ALICE_l2_l2.py)
• (d) Implicit mapping  (ALICE_A_A.py)

Real datasets

MNIST

We study the impact of weighting hyperparameter (\lambda) for CE regularizer. The performance of image generation is evaluated by inception score (ICP), and image reconstruction is evaluted by mean square error (MSE).

Best ICP=9.279 ± 0.07, and MSE=0.0803 ± 0.007, when \lambda=1

Note: we pre-trained a "perfect" MNIST classifier (100% training accuracy) to compute the inception score for MNIST.

CIFAR

Best ICP=6.015 ± 0.0284, and MSE=0.4155 ± 0.2015, when \lambda=1e-6. Larger \lambda leads to lower MSE.

Note: The quality of generated cifar images is evaluated via the inception score based on ImageNet.
