* Add ReutersTrainer, ReutersEvaluator options in Factory classes * Add Reuters to Kim-CNN command line arguments * Fix SST dataset path according to changes in Kim-CNN args The dataset path in args.py was made to point at the dataset folder rather than dataset/SST folder. Hence SST folder was added to paths in the SST dataset class * Add Reuters dataset class, and support in __main__ * Add Reuters dataset trainers and evaluators * Remove debug print statement in reuters_evaluator * Fix rounding bug in reuters_trainer and reuters_evaluator * Add LSTM for baseline text classification measurements * Add eval metrics for lstm_baseline * Set batch_first param in lstm_baseline * Remove onnx args from lstm_baseline * Pack padded sequences in LSTM_baseline * Add TensorBoardX support for Reuters trainer * Add Arxiv Academic Paper Dataset (AAPD) * Add Hidden Bottleneck Layer to BiLSTM * Fix packing of padded tensors in Reuters * Add cmdline args for Hidden Bottleneck Layer for BiLSTM * Include pre-padding lengths in AAPD dataset * Remove duplication of preprocessing code in AAPD * Remove batch_size condition in ReutersTrainer * Add ignore_lengths option to ReutersTrainer and ReutersEvaluator * Add AAPDCharQuantized and ReutersCharQuantized * Rename Reuters_hierarchical to ReutersHierarchical * Add CharacterCNN for document classification * Update README.md for CharacterCNN * Fix table in README.md for CharacterCNN * Add AAPDHierarchical for HAN * Update HAN for changes in Reuters dataset endpoints * Fix bug in CharCNN when running on CPU * Add AAPD dataset support for KimCNN * Fix dataset paths for SST-1 * Fix dimensions of FC1 in CharCNN * Add model checkpointing for Reuters based on F1 * Refactor LSTM baseline __main__ * Add precision, recall and F1 to Reuters evaluator * Checkpoint only at the end of an epoch for ReutersTrainer Add detailed log printing for dev evaluations * Fix log_template and dev_log_template in ReutersTrainer * Add IMDB dataset * Fix duplicate printing of header in ReutersTrainer * Add support for single_label datasets in ReutersTrainer * Add support for IMDB dataset in lstm_baseline and lstm_reg * Fix evaluator call in main method of HAN * Add IMDB for HAN * Fix for single_label * Fix evaluate_dataset method for single_label datasets * Reduce default patience to 5 epochs before early stopping * Revert change to save_state rather than the entire model * Add Yelp 2018 dataset * Integrate Yelp2018 with LSTM baseline * Replace Yelp2018 with Yelp2014 dataset * Add Yelp2014 to LSTM Baseline * Integrate Yelp14 into LSTM Regularization * Remove dropout in HBL for LSTM Baseline and Reg * Add Yelp for HAN * Fix the saving issue for HAN * Fix loading for HAN * Fix typo in ReutersEvaluator * Print to STDOUT rather than logger * Print XML-CNN eval to STDOUT rather than logger * Update max_length for IMDB dataset * Add single_label support for char_cnn * Fix evaluation method for char_cnn * Remove unwanted parameters from ReutersTrainer and ReutersEval * Fix code formatting in lstm_reg/args * Add support for IMDB and Yelp in KimCNN * Fix single_label incorporation * Remove unnecessary conditions * Fix num_classes in Yelp2014 * Add single_label support for XML-CNN * Fix call to evaluator in XML-CNN * Address PEP8 issues * Address PEP8 issues * Address PEP8 issues * Address PEP8 issues
Character-level Convolutional Network
Implementation of Char-CNN from Character-level Convolutional Networks for Text Classification (http://papers.nips.cc/paper/5782-character-level-convolutional-networks-for-text-classification.pdf)
Quick Start
To run the model on Reuters dataset, just run the following from the Castor working directory:
python -m char_cnn --dataset Reuters --gpu 1 --batch_size 128 --lr 0.001
To test the model, you can use the following command.
python -m char_cnn --trained_model kim_cnn/saves/Reuters/best_model.pt
Dataset
We experiment the model on the following datasets.
- Reuters Newswire (RCV-1)
- Arxiv Academic Paper Dataset (AAPD)
Settings
Adam is used for training.

TODO
- Support ONNX export. Currently throws a ONNX export failed (Couldn't export Python operator forward_flattened_wrapper) exception.
- Parameters tuning
