rouge_l_precision: 0.3231 with confidence interval (0.3205, 0.3256)

How to run training:

1. Follow data generation instruction from https://github.com/abisee/cnn-dailymail
2. Run start_train.sh, you might need to change some path and parameters in data_util/config.py
3. For training run start_train.sh, for decoding run start_decode.sh, and for evaluating run run_eval.sh

Note:

• In decode mode beam search batch should have only one example replicated to batch size https://github.com/atulkum/pointer_summarizer/blob/master/training_ptr_gen/decode.py#L109 https://github.com/atulkum/pointer_summarizer/blob/master/data_util/batcher.py#L226

• It is tested on pytorch 0.4 with python 2.7

• You need to setup pyrouge to get the rouge score
