Michela Meo: Greener network operation through machine learning

The talk focuses on the support that machine learning can provide to green  network operation. Green networks combine resource and energy management decisions; where resource management includes the use of sleep modes and resource on demand decisions and energy management involves the choice of which energy source to use, in a power supply system that integrates renewable energy generation into a traditional supply.  The case of a radio access network is made and the impacts of different traffic prediction models on the consumed energy mix and on QoS is evaluated. The results show that a widespread implementation of energy saving strategies without the support of ML would require a careful tuning that cannot be performed autonomously and that needs continuous updates to follow traffic pattern variations. On the contrary, ML approaches provide a versatile framework for the implementation of the desired trade-off that naturally adapts the network operation to the traffic characteristics typical of each area and to its evolution.

Mauro Gasparini e Lidia Sacchetto: Model-based binary classification based on binary data

I will review model based classification, both with hard and soft assignment of the units, in the case of binary features (predictors). I will explore the properties of the ROC curve in this special case and provide some examples. This is joint work with my Ph.d. student Lidia Sacchetto.

Andrea Calimera: ConvNet on Tiny Cores

The promise of the IoT is to improve the quality of services using the information inferred from data collected across distributed platforms. The next generation of smart-objects will be able to distill such information at the edge, where data are generated, by-passing (or at least limiting) the access to the cloud. The success of this strategy involves the deployment of complex data-analytics algorithms, like deep neural models, on low-power devices. The objective of this talk is to introduce practical optimization techniques aimed at improving the energy efficiency of deep neural networks made run on tiny embedded computers.

PhD presentations:
  • Andrea Bordone Molini: Deep neural network for Super-resolution of Unregistered Multitemporal images
  • Giuseppe Attanasio: Quantitative cryptocurrency trading: exploring the use of machine learning techniques
  • Alessandro Destefanis: The impact of Airbnb on the hotels’ economic perfomance
  • Nicola Prette: Video Compression using Neural Networks
  • Sina Famouri: Towards robust training of Faster RCNN for breast mass detection and classification
