Overview

• Proposed model: Stacked Denoising BERT

  

• Task: Text classification from noisy data

  • Twitter Sentiment Classification
  • Incomplete Intent Classification: text with STT error

• Baseline models

  • BERT
  • NLU Platforms: Rasa (spacy and tf), Dialogflow, and SAP Conversational AI
  • Semantic Hashing with Classifier

Requirements

Python 3.6 (3.7.3 tested), PyTorch 1.0.1.post2, CUDA 9.0 or 10.1

pip install --default-timeout=1000 torch==1.0.1.post2
pip install -r requirements.txt
conda install pytorch torchvision cudatoolkit=9.0 -c pytorch

How to Use

1. Dataset

• Chatbot NLU Evaluation Benchmark dataset with missing/incorrect data (STT errors) and Twitter Sentiment dataset (Check Dataset README)
• Training done on:
  • Twitter dataset: complete data, incomplete data, complete+incomplete data
  • Chatbot dataset: complete data, 2 TTS-STT data (gtts-witai, macsay-witai)

2. Pre-fine-tune BERT

• Twitter Sentiment Corpus

CUDA_VISIBLE_DEVICES=0,1 ./scripts/twitter_sentiment/run_bert_classifier_inc_with_corr.sh

Script for Inc+Corr dataset. Scripts corresponding to Inc and Corr are also available in the same folder.

• Chatbot Incomplete Intent Corpus: texts with STT Error

CUDA_VISIBLE_DEVICES=0,1 ./scripts/stterror_intent/run_bert_classifier_stterror.sh

Script for noisy data (stterror). Script for clean, non-noisy data, is also available (complete).

3. Train/test model

• Training on Twitter Corpus

CUDA_VISIBLE_DEVICES=0,1 ./scripts/twitter_sentiment/run_stacked_debert_dae_classifier_twitter_inc_with_corr.sh

Make sure the OUTPUT directory is the same as the fine-tuned BERT or copy the BERT model to your new output dir.

• Training on NLU Evaluation Corpora for TTS=gtts/macsay and STT=witai and autoencoder epochs 100-1000.

CUDA_VISIBLE_DEVICES=0,1 ./scripts/stterror_intent/run_stacked_debert_dae_classifier_stterror.sh

4. Test model

• Testing on NLU Evaluation Corpora

CUDA_VISIBLE_DEVICES=0 python run_stacked_debert_dae_classifier.py --seed 1 --task_name "sentiment140_sentiment" --save_best_model --do_eval --do_lower_case --data_dir ./data/twitter_sentiment_data/sentiment140/ --bert_model bert-base-uncased --max_seq_length 128 --train_batch_size 4 --eval_batch_size 1 --learning_rate 2e-5 --num_train_epochs_autoencoder 3 --num_train_epochs 3 --output_dir_first_layer "./results/test/results_stacked_debert_dae_earlyStopWithEvalLoss_twitter_10seeds/inc_with_corr_sentences_TestOnlyIncorrect/sentiment140_ep3_bs4_inc_with_corr_TestOnlyIncorrect_seed1_first_layer_epae1000/" --output_dir "./results/test/results_stacked_debert_dae_earlyStopWithEvalLoss_twitter_10seeds/inc_with_corr_sentences_TestOnlyIncorrect/sentiment140_ep3_bs4_inc_with_corr_TestOnlyIncorrect_seed1_second_layer_epae1000/"
