Overview

Adversarially Learned Inference

Code for the Adversarially Learned Inference paper.

Compiling the paper locally

From the repo's root directory,

$ cd papers
$ latexmk --pdf adverarially_learned_inference

Requirements

Blocks, development version
Fuel, development version

Setup

Clone the repository, then install with

$ pip install -e ALI

Downloading and converting the datasets

Set up your ~/.fuelrc file:

$ echo "data_path: \"<MY_DATA_PATH>\"" > ~/.fuelrc

Go to <MY_DATA_PATH>:

$ cd <MY_DATA_PATH>

Download the CIFAR-10 dataset:

$ fuel-download cifar10
$ fuel-convert cifar10
$ fuel-download cifar10 --clear

Download the SVHN format 2 dataset:

$ fuel-download svhn 2
$ fuel-convert svhn 2
$ fuel-download svhn 2 --clear

Download the CelebA dataset:

$ fuel-download celeba 64
$ fuel-convert celeba 64
$ fuel-download celeba 64 --clear

Training the models

Make sure you're in the repo's root directory.

CIFAR-10

$ THEANORC=theanorc python experiments/ali_cifar10.py

SVHN

$ THEANORC=theanorc python experiments/ali_svhn.py

CelebA

$ THEANORC=theanorc python experiments/ali_celeba.py

Toy task

$ THEANORC=theanorc python experiments/ali_mixture.py

$ THEANORC=theanorc python experiments/gan_mixture.py

Evaluating the models

Samples

$ THEANORC=theanorc scripts/sample [main_loop.tar]

e.g.

$ THEANORC=theanorc scripts/sample ali_cifar10.tar

Interpolations

$ THEANORC=theanorc scripts/interpolate [which_dataset] [main_loop.tar]

e.g.

$ THEANORC=theanorc scripts/interpolate celeba ali_celeba.tar

Reconstructions

$ THEANORC=theanorc scripts/reconstruct [which_dataset] [main_loop.tar]

e.g.

$ THEANORC=theanorc scripts/reconstruct cifar10 ali_cifar10.tar

Semi-supervised learning on SVHN

First, preprocess the SVHN dataset with the learned ALI features:

$ THEANORC=theanorc scripts/preprocess_representations [main_loop.tar] [save_path.hdf5]

e.g.

$ THEANORC=theanorc scripts/preprocess_representations ali_svhn.tar ali_svhn_preprocessed.hdf5

Then, launch the semi-supervised script:

$ python experiments/semi_supervised_svhn.py ali_svhn.tar [save_path.hdf5]

e.g.

$ python experiments/semi_supervised_svhn.py ali_svhn_preprocessed.hdf5

[...]
Validation error rate = ... +- ...
Test error rate = ... +- ...

Toy task

$ THEANORC=theanorc scripts/generate_mixture_plots [ali_main_loop.tar] [gan_main_loop.tar]

e.g.

$ THEANORC=theanorc scripts/generate_mixture_plots ali_mixture.tar gan_mixture.tar

Conditional Generation

I'm interested in getting the update to this codebase that includes the conditional generation, as covered in the more recent version of the paper (related image below). Can you let me know if that will be added to the repo?

mistake in D(x,z) input size

In table 5 from the paper you state that the input size for D(x,z) is 1024x1x1 which I think it's wrong after looking at the previous output sizes D(x) and D(z). I think that should be 1536x1x1.

Is that assumption correct?

deserialization of models hangs

Training goes well for me using the scripts in experiments with the latest version of blocks, but then when I run any subsequent command that uses the generated model like scripts/sample or scripts/reconstruct, the command hangs indefinitely. My guess is that the deserialization is getting jammed up.

I can look into it more - not yet familiar with the new tar format - but curious if this might be a known issue.

Fuel version problem

I installed the current development version of fuel, but had some issue in fuel downloading.

$ fuel-download celeba 64 $ fuel-convert celeba 64 $ fuel-download celeba 64 --clear

The error message I got is: fuel-download: error: unrecognized arguments: 64 if I remove 64, I got: TypeError: init() got an unexpected keyword argument 'max_value'

Could someone please specify what version or commits of fuel and progressbar should I use? Thanks

Where to use the reparametrization trick

In the decoder module. I found that z is sampled from N(0, 1), so where did you use the reparametrization trick described in formual (2) and (3) in the paper

semi-supervised learning

Hello,I read the paper and the source code.And it mentioned 'The last three hidden layers of the encoder as well as its output are concatenated to form a 8960-dimensional feature vector.' in section 4.3 of the paper.Could you please tell me how to compute the dimension?Thanks very much

ImportError: No module named ali.utils

I followed the same steps in the readme file, but when I run this line

$ THEANORC=theanorc python experiments/ali_cifar10.py

I get:

Traceback (most recent call last):
  File "experiments/ali_cifar10.py", line 3, in <module>
    from ali.utils import get_log_odds, conv_brick, conv_transpose_brick, bn_brick
ImportError: No module named ali.utils

Preprocess_representation has a bug for me

Hi, I was trying to reproduce the representation learning results of paper. Everything works fine except "preprocess_representations" script. It is leading to this error:

File "scripts/preprocess_representations", line 32, in preprocess_svhn bricks=[ali.encoder.layers[-9], ali.encoder.layers[-6], AttributeError: 'GaussianConditional' object has no attribute 'layers'

Any help would be appreciated.

Semi-supervised learning

I've been trying to reproduce your figures for semi-supervised learning on CIFAR-10 (19.98% with 1000 labels). This result is based on the technique proposed in Salimans et al. (2016), not SVMs. Is there any way you can include your code, or at least any changes to the hyperparameters in ali_cifar10.py?

Thanks in advance for your help.
