Bespoke系统利用现有讲座文字记录，为不同行业和时长自动生成定制化讲座视频，经专家评估，87%的视频达到MOOC质量水平，且成本低廉。
AI 中文摘要
来自不同行业的终身学习者常常观看相同的录制讲座，即使他们将在不同的工作场所应用这些材料。我们提出了Bespoke系统，该系统利用现有讲座的文字记录，生成针对目标行业和时长的定制新视频，包含新的幻灯片、旁白和图表。从分析学、机器学习和优化领域的31个研究生讲座中，我们为这三个行业生成了209个视频，并为每个讲座生成了一个面向普通受众的版本。25位相应领域的专家按照五分制评分标准对92个视频进行了评分。他们判定87%的视频达到或超过评分标准中点，即相当于“标准MOOC讲座的质量”（平均总分为3.42分（满分5分）；48%的视频得分为4分或以上）。总体质量在不同行业、不同时长以及开发系统时未使用的21个讲座的留出集上表现相似，视频每分钟的API成本约为0.22美元。
英文摘要
Lifelong learners from different industries often watch the same recorded lecture, even when they will apply the material in different workplaces. We present Bespoke, a system that takes the transcript of an existing lecture and generates a new video customized to a target industry and duration, with new slides, narration, and charts. From 31 graduate lectures in analytics, machine learning, and optimization, we generated 209 videos for these three industries, plus a generic-audience version of each lecture. Twenty-five experts in the corresponding domains rated 92 videos on a five-point rubric. They judged 87% at or above the rubric midpoint corresponding to ``a standard MOOC lecture's quality'' (mean overall score 3.42 out of 5; 48% scored 4 or above). Overall quality was similar across industries, durations, and a 21-lecture held-out set unused while developing the system, at about \$0.22 API cost per minute of video.
