Improving Multi-turn Emotional Support Dialogue Generation with Lookahead Strategy Planning
Bibliographic record
Abstract
Providing Emotional Support (ES) to soothe people in emotional distress is an essential capability in social interactions.Most existing research on building ES conversation systems only considers single-turn interactions with users, which is over-simplified.In comparison, multi-turn ES conversation systems can provide ES more effectively, but face several new technical challenges, including: i) how to conduct support strategy planning that could lead to the best supporting effects; ii) how to dynamically model the user's state.In this paper, we propose a novel system named MultiESC to address these issues.For strategy planning, drawing inspiration from the A* search algorithm, we propose lookahead heuristics to estimate the future user feedback after using particular strategies, which helps to select strategies that can lead to the best long-term effects.For user state modeling, MultiESC focuses on capturing users' subtle emotional expressions and understanding their emotion causes.Extensive experiments show that MultiESC significantly outperforms competitive baselines in both strategy planning and dialogue generation.Our codes are available at https: //github.com/lwgkzl/MultiESC.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
