Google、人工知能ライブラリ TensorFlow をオープンソース化。音声検索や写真認識、翻訳の基盤技術ディープラーニングを商利用可で解放
http://japanese.engadget.com/2015/11/09/google-tensorflow/
でました。
Mac 環境へのインストール
brew install python pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl
MNIST のサンプル実行
MNIST は大量の学習サンプル、テストサンプルからなる手書き数字画像データベースです。
ディープラーニングで活用されています。
git clone --recurse-submodules https://github.com/tensorflow/tensorflow cd tensorflow/ python tensorflow/models/image/mnist/convolutional.py
これでサンプル実行できます。
MNISTの手書きの数字ファイルを取得して、学習が始まります。
