Welcome!

This is the official web site of Siena Artificial Intelligence Laboratory. The focus of our research is on machine learning. In the last few years, we’ve been mainly involved in the conception of new theories of learning in structured domains and in their applications to pattern recognition and mining the web. We are also interested […]

[April 12th 2018] LabMeeting: Synthetic data generation for semantic segmentation

Paolo Andreini(DIISM, University of Siena) April 12, 2018 – 9:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description In recent years, deep learning techniques have push the state of the art in many visual recognition tasks, based on fully annotated data by human experts. Nevertheless, this annotation procedure is inherently difficult and costly, […]

[April 5th 2018] LabMeeting: Convolutional Networks in Visual Environments

Alessandro Betti (DIISM, University of Siena) April 5, 2018 – 9:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description The puzzle of computer vision might find new challenging solutions when we realize that most successful methods are working at image level, which is remarkably more difficult than processing directly visual streams. In this […]

[March 29th 2018] LabMeeting: LogSCM – Logical Support Constraint Machines

Francesco Giannini (DIISM, University of Siena) March 29, 2018 – 9:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description The success of support vector machines lies in the fact that only a small portion of data are significant to determine the maximum margin hyperplane separating two opposite class of labeled examples, namely the […]

[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, […]

[March 15th, 2018] CLARE: a Constrained Learning And Reasoning Environment

Giuseppe Marra (DIISM, University of Siena) March 15th, 2018 – 9:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description In spite of the amazing results of deep learning in many applications, a real intelligent behavior of an agent, acting in a complex environment, is likely to require some kind of higher-level symbolic inference. […]

[March 8th, 2018] LabMeeting: Refinement of deep neural network learning via error-driven target propagation

Vincenzo Laveglia (DIISM, University of Siena) March 8, 2018 – 9:30 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Target propagation in deep neural networks aims at improving the learning process by determining target outputs for the hidden layers of the network. To date, this has been accomplished relying on autoassociative networks applied […]
