フォルダ構成
- MNIST:
http://yann.lecun.com/exdb/mnist/
からダウンロードしたMNISTのデータ(gz形式)を置く。
- visualization:pklファイルと、元画像と復元画像のペアの画像を保存
- models:tensorflowのチェックポイントを保存
- input_data.py:MNISTのデータ読み込むコード
https://github.com/tensorflow/tensorflow/blob/r0.7/tensorflow/examples/tutorials/mnist/input_data.py
- mmd_VAE.py:AutoEncoderのコード(これを実行する)
