Abstract: In accordance with techniques for context-driven generation of diverse questions, a machine learning model receives a first target question, a second target question, and a context. Based on the context and one or more words of the first target question, a first decoder of the machine learning model outputs a first representation of candidate words to follow the one or more words of the first target question. Based on the context and one or more words of the second target question, a second decoder of the machine learning model outputs a second representation of candidate words to follow the one or more words of the second target question. The machine learning model is fine-tuned to generate diverse questions for a given context based on a diversity loss that captures a degree of variance between the first representation and the second representation.

Abstract: A system may receive, via a user interface associated with an online marketplace, a request to generate the listing for the item, the request including a natural language text input as a title for the listing. The system may generate, based on inputting the natural language text to a transformer-based machine learning model, a predicted value for an item description attribute of the item. In some examples, a value of the item description attribute may be unspecified in the natural language text and may describe a feature associated with the item as produced. The system may then cause presentation, via the user interface associated with the online marketplace, of the listing including the predicted value for the item description attribute.
