Transfer-Learning based on Extract, Paraphrase and Compress Models for Neural Abstractive Multi-Document Summarization
Bibliographic record
Abstract
Recently, transfer-learning by unsupervised pre-training and fine-tuning has shown great success on a number of tasks.The paucity of data for multi-document summarization (MDS) in the news domain, especially makes this approach practical.However, while existing literature mostly formulate unsupervised learning objectives tailored for/around the summarization problem we find that MDS can benefit directly from models pre-trained on other downstream supervised tasks such as sentence extraction, paraphrase generation and sentence compression.We carry out experiments to demonstrate the impact of zero-shot transfer-learning from these downstream tasks on MDS.Since it is challenging to train end-to-end encoderdecoder models on MDS due to i) the sheer length of the input documents, and ii) the paucity of training data.We hope this paper encourages more work on these downstream tasks as a means to mitigating the challenges in neural abstractive MDS.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
