Yuefu is a poetry generation system using OpenAI’s GPT, a Generative Pre-Trained natural language model pretrained on Chinese newspapers, that is fine-tuned with classical Chinese poetry. The developers write in their paper describing the system that it does not use "human crafted rules or features," or "any additional neural components". The system can generate poems in various formal, classical styles.
The example shown is translated by Ru-Ping Cheng and Jeff Ding for the ChinAI newsletter. It is an example of Cang Tou Shi, a Chinese version of acrostic poems. "In this case," the translator explains, "the first words of each line form the title of the poem: 神经网络 (neural networks)." Some other examples of the system's output are shown in a preprint published by the system's creators, and a translation of a Chinese newspaper article (entered into ELMCIP) provides translations of more examples.
