Planning Augmented Cities in the Neoanthropocene
2020
To improve the effects of the connecting “augmented urbanism”, I have set up ten keywords able to reset spatial planning for the Augmented City in the face of the 21st century challenges. The Augmented City’s practices grow with exponential progression doubling its components, connections and impacts seen in the last years, to one incredible and disruptive acceleration. We are surrounded by thousands of practices in the spread of sensors and intelligent devices, in collaborative design and return of urban manufacturing, in explosion of creativity and increase of resilience, and several experiments in recycling of everything, fluidisation and networking of cities, and adoption of incremental…
Designing for Mixed Reality Urban Exploration
2021
Funding Information: Acknowledgments. This work was supported by the European Union Seventh Framework Programme (grant agreement no 601139) and the Italian Ministry of Education, University, and Research (MIUR) PON AIM project (id: AIM1875400-1, CUP: B74I18000210006). Publisher Copyright: © 2021. All Rights Reserved. This paper introduces a design framework for mixed reality urban exploration (MRUE), based on a concrete implementation in a historical city. The framework integrates different modalities, such as virtual reality (VR), augmented reality (AR), and haptics-audio interfaces, as well as advanced features such as personalized recommendations, social exploration, and itinerary manage…

Improving Irony and Stereotype Spreaders Detection using Data Augmentation and Convolutional Neural Network
2022
In this paper we describe a deep learning model based on a Data Augmentation (DA) layer followed by a Convolutional Neural Network (CNN). The proposed model was developed by our team for the Profiling Irony and Stereotype Spreaders (ISSs) task proposed by the PAN 2022 organizers. As a first step, to classify an author as ISS or not (nISS), we developed a DA layer that expands each sample in the dataset provided. Using this augmented dataset we trained the CNN. Then, to submit our predictions, we apply our DA layer on the samples within the unlabeled test set too. Finally we fed our trained CNN with the augmented test set to generate our final predictions. To develop and test our model we us…
Combining intelligent recommendation and mixed reality in itineraries for urban exploration
2017
Exploration of points of interest (POI) in urban environments is challenging for the large amount of items near or reachable by the user and for the modality hindrances due to reduced manual flexibility and competing visual attention. We propose to combine different modalities, VR, AR, haptics-audio interfaces, with intelligent recommendation based on a computational method combining different data graph overlays: social, personal and search-time user input. We integrate such features in flexible itineraries that aid different phases and aspects of exploration.
Does More Context Help? Effects of Context Window and Application Source on Retrieval Performance
2021
We study the effect of contextual information obtained from a user’s digital trace on Web search performance. Contextual information is modeled using Dirichlet–Hawkes processes (DHP) and used in augmenting Web search queries. The context is captured by monitoring all naturally occurring user behavior using continuous 24/7 recordings of the screen and associating the context with the queries issued by the users. We report a field study in which 13 participants installed a screen recording and digital activity monitoring system on their laptops for 14 days, resulting in data on all Web search queries and the associated context data. A query augmentation (QAug) model was built to expand the or…
Retinal image synthesis through the least action principle
2020
Eye fundus image analysis is a fundamental approach in medical diagnosis and follow-up ophthalmic diagnostics. Manual annotation by experts needs hard work, thus only a small set of annotated vessel structures is available. Examples such as DRIVE and STARE include small sets for training images of fundus image benchmarks. Moreover, there is no vessel structure annotation for a number of fundus image datasets. Synthetic images have been generated by using appropriate parameters for the modeling of vascular networks or by methods developing deep learning techniques and supported by performance hardware. Our methodology aims to produce high-resolution synthetic fundus images alternative to the…
An Agent-based Service Network for Personal Mobile Devices
2006
We propose the Agent Network for Bluetooth Devices, a system that uses personal mobile devices as adaptive human-environment interfaces to supply people with ad hoc information and high-level services. The ANBD system operates with a hierarchical framework of service-providing nodes, dynamically composed and managed by mobile agents.
