Densely Connected CNN with Multi-scale Feature Attention for Text Classification

Densely-Connected-CNN-with-Multi-scale-Feature-Attention

For Text Classification

Introduction

Densely Connected CNN with Multi-scale Feature Attention for Text Classification is initially described in an IJCAI-ECAI 2018 paper. It provides a new CNN architecture to produce variable n-gram features. It is worth nothing that:

• It uses dense connections to build short-cut paths between upstream and downstream convolutional blocks, which enable the model to compose features of larger scale from those of smaller scale, and thus produce variable n-gram features.
• A multi-scale feature attention is developed to adaptively select multi-scale features for classification.
• It obtains competitive performance against state-of-the-art baselines on six benchmark datasets.

Preparation for Training & Testing

1. Please clone the Densely-Connected-CNN-with-Multiscale-Feature-Attention repository, and we call the directory that you cloned as ${DenseAttention_ROOT}.

2. please clone the Caffe from caffe_for_text and build it. It is a modified version of the offical repository.

3. Please download text classification datasets from benchmark datasets which are releasd by Zhang et al., 2015. AGNews in $(DenseAttention_ROOT)/data/ag_news_csv is an example dataset in this repo.

4. Please download pretrained word vectors from Glove.

Usage

1. Prepare training & testing data by using original datasets, pretrained word vectors and tools in $(DenseAttention_ROOT)/data/gen_data.py. An example is in $(DenseAttention_ROOT)/data/agnews.

2. Generate the training & testing prototxt by using tools in $(DenseAttention_ROOT)/script/gen_model.py.

3. To perform experiments, run the script with the corresponding config file as input. For example, to train and test, use the following command

   cd $(DenseAttention_ROOT)/experiment
   ./train.sh
   

   This example uses 4 NVIDIA Titan X Pascal GPUs and the trained model as well as logs are saved in $(DenseAttention_ROOT)/experiment.

4. Please find more details in config files and in our code.
