On the Integration of Logic and Learning

Giannini’s thesis A key point in the success of machine learning, and in particular deep learning, has been the availability of high-performance computing architectures allowing to process a large amount of data. However, this potentially prevents a wider application of machine learning in real world applications, where the collection of training data is often a […]

[Feb 19th 2020] LabMeeting: Embedding of FRPN in CNN architecture

Alberto Rossi (University of Florence) Feb 19, 2020 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description This paper extends the fully recursive perceptron network (FRPN) model for vectorial inputs to include deep convolutional neural networks (CNNs) which can accept multi-dimensional inputs. A FRPN consists of a recursive layer, which, given a […]

[Feb 19th 2020] LabMeeting: The Latent Topic Block Model for the Co-Clustering of Textual Interaction Data

Marco Corneli Feb 19, 2020 – 11:45 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description We consider textual interaction data involving two disjoint sets of individuals/objects. An example of such data is given by the reviews on web platforms (e.g. Amazon, TripAdvisor, etc.) where buyers comment on products/services they bought. We develop a […]

[Feb 12th 2020] Creating a Commonsense Knowledge Base about Objects

Valerio Basile (University of Turin) Feb 12, 2020 – 11:40 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Today’s Web represents a huge repository of human knowledge, not only about facts, people, places and so on (encyclopedic knowledge), but also about everyday beliefs that average human beings are expected to hold (commonsense knowledge). […]

[Feb 5th 2020] LabMeeting: Line-Based Automatic Sketches

Lisa Graziani (University of Florence) Feb 5, 2020 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Sketch generation from photos can be seen as a classic task of image to image translation with GANs. But in our work the sketch generation is addressed as an unsupervised problem based on a vectorial […]

[Jan 29th 2020] LabMeeting: Learning in Text Streams, Discovery and Disambiguation of Entity and Relation Instances

Andrea Zugarini (University of Florence) Jan 29, 2020 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description We consider a scenario where an artificial agent is reading a stream of text composed of a set of narrations, and it is informed about the identity of some of the individuals that are mentioned […]

[Jan 22nd 2020] LabMeeting: Analyzing and Improving the Image Quality of StyleGAN

Giorgio Ciano (University of Siena) Jan 22, 2020 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description The style-based GAN architecture (StyleGAN) yields state-of-the-art results in data-driven unconditional generativeimage modeling. We expose and analyze several of its characteristic artifacts, and propose changes in both model architecture and training methods to address them. […]

[Jan 15th 2020] LabMeeting: Toward in silico Design of Rhodopsin Mutants by integrating Hybrid QM/MM and Machine Learning Approaches

Anna Visibelli (University of Siena) Jan 15, 2020 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Microbial rhodopsins, light-dependent ion-transporting membrane proteins, are widely used in optogenetics, due to their low phototoxicity and high tissue penetration. To widen possible optogenetic applications (e.g., diverse optical control of neural activity) novel rhodopsins, exhibiting […]
