tensorflow-example(Now support text/sparse-input classfication/regression)

stop update, you can find new code in hasky/applications

using tf-record(suggeted, only tested with tf.version 1.0.0)

see README.md in ./examples
incase not find dependence, make sure set PYTHONPATH to include tensorflow-example/util so we can find gezi and melt

without tf-record(depreciated)

cd ./depreciated

basic tensorflow examples of doing binary classification will show auc result for each epoch It can deal with both dense or sparse input(like 3:2.5 1234:6.7)

#binary classification of dense input data using logistic regression python ./binary_classification.py --train ./data/feature.normed.rand.12000.0_2.txt --test ./data/feature.normed.rand.12000.1_2.txt python ./binary_classification.py --train ./data/feature.normed.rand.12000.0_2.txt --test ./data/feature.normed.rand.12000.1_2.txt --method mlp

#binary classification of sparse input data using logistic regression python ./binary_classification.py --train ./data/feature.trate.0_2.normed.txt --test ./data/feature.trate.1_2.normed.txt
python ./binary_classification.py --train ./data/feature.trate.0_2.normed.txt --test ./data/feature.trate.1_2.normed.txt --method mlp
