Humans have the extraordinary ability to learn continually from experience. Not only we can apply previously learned knowledge and skills to new situations, we can also use these as the foundation for later learning. One of the grand goals of Artificial Intelligence (AI) is building an artificial “continual learning” agent that constructs a sophisticated understanding of the world from its own experience through the autonomous incremental development of ever more complex knowledge and skills. However, despite early speculations and few pioneering works, very little research and effort has been devoted to address this vision. Current AI systems greatly suffer from the exposure to new data or environments which even slightly differ from the ones for which they have been trained for. Moreover, the learning process is usually constrained on fixed datasets within narrow and isolated tasks which may hardly lead to the emergence of more complex and autonomous intelligent behaviors. In essence, continual learning and adaptation capabilities, while more than often thought as fundamental pillars of every intelligent agent, have been mostly left out of the main AI research focus. In this PhD course, we will study the application of these ideas in light of the more recent advances in machine learning research and in the context of deep architectures for AI. We will start with an introduction to the topic, highlighting its relationship with related research areas and a comprehensive guide to the founding concepts of continual learning. The main portion of the course, instead, will be dedicated to the introduction to state-of-the-art benchmarks, strategies and evaluation methodologies. The third and final part of the course will concern practical recommendation, real-world applications and interesting research directions for the future of this exciting research topic.
Every lecture contains a hands-on session using the Avalanche continual learning library, partially developed at UNIPI.
Final exam: Project based on personal interests or by lecturer’s suggestion.

Component-wise definition of programming languages
Lecturers: Egon Boerger
Period: From February 28th to March 18th, 2022
Schedule: Monday+Wednesday+Friday from 11am(sharp) to 12:30pm,
To attend the course, please send an email to firstname.lastname@example.org
The course presents a general method for component-wise abstract definition and provably correct implementation of a wide range of programming languages. In the first part of the course the approach is applied to piecemeal provide an abstract model for the execution of the constructs which define well-known programming languages belonging to different paradigms (imperative, logical, object-oriented, parallel). The resulting interpreters rigorously define the semantics of the languages involved (Pascal, Prolog, Java, C#, Occam) and can be shown to be correctly refinable on a target machine based upon an appropriate compilation scheme of the underlying constructs. In the second part of the course the students choose a (for example domain-specific or application programming) language to apply the method to typical constructs of such languages.
Design Thinking for Scientists
Lecturers: Daniele Mazzei
Period: From March 21st to April 8th, 2022
To attend the course, please register here. For further information please send an email to email@example.com
Design Thinking is an iterative process in which we seek to understand the user, challenge assumptions, and redefine problems in an attempt to identify alternative strategies and solutions that might not be instantly apparent with our initial level of understanding. Design Thinking provides a solution-based approach to solving problems. It is a way of thinking and working as well as a collection of hands-on methods. Design Thinking is not an exclusive property of designers all great innovators in literature, art, music, science, engineering, and business have practiced it. The course will introduce to design thinking and human centered design approaches giving PhD students an overall view on how this methods can be applied to the research context.
Big Data Analytics: Marine Data as a Case Study
Lecturers: Gianpaolo Coro (ISTI-CNR)
Period: From April 26th to April 29th, 2022
Schedule: 4 hours per day (9am-1pm)
To attend the course, please send an email to firstname.lastname@example.org
In this course, practical methodologies for marine data analysis and modelling will be presented. The course will cover specific classes of problems in marine science and their corresponding solutions, adopting state-of-the-art computer science technologies and methodologies. The explained techniques will include:
1) Unsupervised approaches to discover patterns of habitat change and predict fishing vessel activity patterns: Principal Component Analysis and Maximum Entropy for feature selection; KMeans, XMeans, DBScan, and Local Outlier Factor cluster analysis; Singular Spectrum Analysis for time series forecasting;
2) Supervised approaches for species distribution prediction and invasive species monitoring: Feed-Forward Artificial Neural Networks, Support Vector Machines, AquaMaps, Maximum Entropy;
3) Bayesian state-space models to predict fish stock availability in specific fishing areas: Monte Carlo and Markov Chain Monte Carlo models;
These methods will be applied to marine data such as vessel transmitted data, species observation records, and catch and vessel time series that fall into the Big Data category. These data are crucial to safeguard food availability and economic welfare, which are fundamental to human life. For example, predicting the impact of climate change on species habitat distribution contributes to avoiding economic and biodiversity collapse due to sudden ecosystem change. Likewise, monitoring the effect of overfishing on fish stocks and marine biodiversity prevents ecosystem and economic collapse.
The explained techniques will address real use cases of the United Nations (FAO, UNESCO, UNEP, and others) for marine food and ecosystem safety and illustrate the new lines of research in this context. They are also general enough to be applied to Big Data of other domains. The analysed data have indeed general characteristics of Big Data such as constantly incrementing volume, vast heterogeneity and complexity, and unreliable content. For this reason, the methodologies will be illustrated in the context of the Open Science paradigm, characterized by the repeatability, reproducibility, and cross-domain reuse of all experimental phases.
The course will be interactive and made up of practical exercises. Attendees will use online environments to parametrize the models, run the experiments, and potentially modify the models. Experiment completion will be valid as the exam.
