machine learning algorithm sample code. Most of them are python. tensorflow folder includes implementation using tensorflow.
Sample code to explain tensorflow concepts.
Basic linear classification using tensorflow. Although this is simple algorithm, but it explains major steps in machine learning very clearly.
A simple image classifier using CNN. It is modified to read black and white bitmap images containing a number in Chinese and outputs its arabic number, e.g. 七 as 7. The bitmap size must be 128 by 128.
docker run --name mlearn -v $PWD:/root/ -it gcr.io/tensorflow/tensorflow bash
cd /root/tensorflow
python sample_mnist.py --step 10000 # train 10k steps
python sample_mnist.py --predict data/0x4e03.bmp # predict an image
Modify AK's RNN gist to support unicode. It can also run on the history data of lottery to predict the next number:P
python mini-char-rnn.py -i input_chinese.txt -l 40
python mini-char-rnn.py -i lottery.txt -l 30 -n -test 08
Sample outputs of Chinese poems:

赧郎长水月皆海。
帝扫莫兮巴死水，寒高宿云鸯鞭间径，有尔同东黄金，栗藏访梦流，山女苍空乌去时，谢放营高晖。
鸡为去浪淡被。
落君如日。萧光芙馥州，秋君欲人相。
郎花必地锦张鱼，飞之莫三云

青虎，何德横贵绣。
六留君不独去，埋花数何骄。照师黩死萦支声。江酣落自望朝桃花上霜烟。
黄鹤楼耳金玉，胡有月舟似，翡歌看低又入海，鼓水出几闲。系失垂杨江，转明霜珠。
挥戈曲千愁欲行，功起楚清，然
