摘要:

幽默生成对大语言模型(LLMs)构成重大挑战,因为其标准训练目标(下一个词预测)与喜剧所需的意外性和不协调性存在固有冲突。为弥合这一差距,我们引入了认知协同框架,这是一种受幽默心理学理论启发的高质量幽默数据生成方法。利用混合思维(MoT)方法,我们部署了六种认知角色(例如荒诞主义者、愤世嫉俗者)来为给定提示合成多样化的喜剧视角。该框架产生了一个基于理论的数据集,我们使用该数据集微调了一个7B参数的学生模型。我们进一步评估了两种对齐策略:直接偏好优化(DPO)和一种离线组相对变体O-GRPO,发现两者均未优于SFT。然而,我们的7B HumorGen模型变体显著优于更大的指令微调基线,并达到顶级开源权重性能,同时与前沿专有系统保持竞争力。这些结果表明,对于幽默生成,认知驱动的数据策展比对齐算法或模型规模更为关键。

英文摘要:

Humor generation poses a significant challenge for Large Language Models (LLMs), because their standard training objective (next-token prediction) inherently conflicts with the surprise and incongruity required for comedy. To bridge this gap, we introduce the Cognitive Synergy Framework, a methodology for generating highquality humor data inspired by psychological theories of humor. Utilizing a Mixtureof-Thought (MoT) approach, we deploy six cognitive personas (e.g., The Absurdist, The Cynic) to synthesize diverse comedic perspectives for a given prompt. This framework produces a theory-grounded dataset, which we use to fine-tune a 7B-parameter student model. We further evaluate two alignment strategies, Direct Preference Optimization (DPO) and an offline group-relative variant O-GRPO, finding that neither improves over SFT. However, our 7B HumorGen model variants significantly outperform larger instruction-tuned baselines and achieve top-tier open-weight performance while remaining competitive with frontier proprietary systems. These results suggest that cognitively driven data curation is more critical than alignment algorithms or model scale for humor generation.
