[March 22nd 2018] LabMeeting Extra: Excursus in the State of the art of object detection – Deep learning models, performance, practical tests

Matteo Tiezzi (DIISM, University of Siena) March 22, 2018 – 10:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description In image classification an image with a single object is the focus and the task is to say what it contains. But when we look at the world around us, we carry out far […]

[March 22nd 2018] LabMeeting: Dialogue Generation from Structured Knowledge

Andrea Zugarini (DIISM, University of Siena) March 22, 2018 – 9:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Current task-oriented dialogue systems are limited to operate in a pre-defined domain. They provide good performances, but they lack of generalization capabilities because of their bound with the specific task. On the other hand, […]
