用卷积神经网络基于 Tensorflow 实现的中文文本分类

项目地址：
https://github.com/fendouai/Chinese-Text-Classification
欢迎提问：http://tensorflow123.com/

这个项目是基于以下项目改写：
cnn-text-classification-tf

主要的改动：
* 兼容 tensorflow 1.2 以上
* 增加了中文数据集
* 增加了中文处理流程

特性：

• 兼容最新 TensorFlow
• 中文数据集
• 基于 jieba 的中文处理工具
• 模型训练，模型保存，模型评估的完整实现

以下为原项目的 README

This code belongs to the “Implementing a CNN for Text Classification in Tensorflow” blog post.

It is slightly simplified implementation of Kim’s Convolutional Neural Networks for Sentence Classification paper in Tensorflow.

Requirements

• Python 3
• Tensorflow > 1.2
• Numpy

Training

Print parameters:

[code lang=bash]
./train.py –help
[/code]

[code lang=text]
optional arguments:
-h, –help show this help message and exit
–embedding_dim EMBEDDING_DIM
Dimensionality of character embedding (default: 128)
–filter_sizes FILTER_SIZES
Comma-separated filter sizes (default: '3,4,5')
–num_filters NUM_FILTERS
Number of filters per filter size (default: 128)
–l2_reg_lambda L2_REG_LAMBDA
L2 regularizaion lambda (default: 0.0)
–dropout_keep_prob DROPOUT_KEEP_PROB
Dropout keep probability (default: 0.5)
–batch_size BATCH_SIZE
Batch Size (default: 64)
–num_epochs NUM_EPOCHS
Number of training epochs (default: 100)
–evaluate_every EVALUATE_EVERY
Evaluate model on dev set after this many steps
(default: 100)
–checkpoint_every CHECKPOINT_EVERY
Save model after this many steps (default: 100)
–allow_soft_placement ALLOW_SOFT_PLACEMENT
Allow device soft device placement
–noallow_soft_placement
–log_device_placement LOG_DEVICE_PLACEMENT
Log placement of ops on devices
–nolog_device_placement

[/code]

Train:

[code lang=bash]
./train.py
[/code]

Evaluating

[code lang=bash]
./eval.py –eval_train –checkpoint_dir="./runs/1459637919/checkpoints/"
[/code]

Replace the checkpoint dir with the output from the training. To use your own data, change the eval.py script to load your data.
