A2 - Quantum Estimation of Distribution Algorithms for Network Optimization Problems (Q@TN Project) (1 grant)

Quantum Annealing, the process through which specialized hardware can, over repeated samplings, probabilistically approximate the optimal solution to a given optimization problem, is a powerful tool for solving a number of problems which can be too difficult to solve using classical approaches. However, while the number of qubits available in modern quantum annealing machines is constantly increasing, the size of the problems that quantum annealers can tackle is still somehow limited.
Evolutionary Algorithms (EAs), a kind of optimization algorithms that iteratively "mutate" and "recombine" a certain number of solutions, have on the other hand proven successful on several hard-to-solve problems, even at large scales. Typically, EAs use a large number of solutions. However, a class of EAs called Estimation of Distribution Algorithms (EDAs) is characterized by a limited amount of memory as they model and evolve a "compact" probability distribution from which solutions are iteratively sampled, rather than using an actual "population". Therefore, a parallel between Quantum Annealers and EDAs can be drawn.
The primary goal of this PhD project is then to design and implement EDAs on quantum annealers. Firstly, the performance of quantum EDAs will be compared with that of traditional ones. Secondly, the developed techniques will be applied to challenging network optimization problems, such as the optimal routing of traffic demands under the constraints of packet- or circuit-based technologies, or the design of Quantum Key Distribution sub-networks at minimal cost.

A3 - Hybrid Quantum-Annealer Algorithms for Tabu search and Data-Driven Computation (Q@TN Project) (1 grant)

The current availability of limited quantum hardware requires to devise hybrid quantum-classical algorithms that take advantage of the existing hardware and overcome their limitations by combining classical and quantum computation. One of the existing hardware, the D-Wave quantum annealer, solves optimization problems however its architecture suffers from limitations in the actual encoding of the target functions. A novel quantum-classical technique is based on a local search where already-visited solutions are penalized to avoid a redundant exploration of the solution space (so-called tabu search paradigm). Tabu search is implemented in the quantum annealer by a sequence of re-initializations of the Ising Hamiltonian of the qubit network iterated within the hybrid quantum-classical structure. An algorithm of Quantum Annealer Tabu Search (QATS) has been proposed in a recent paper (
The PhD candidate will implement and test hybrid quantum classical algorithms that can run on a quantum annealer. Initially, the PhD program will focus on the existing QATS algorithm. The expected result is a complexity-characterized, implemented and empirically evaluated tabu search quantum- classical algorithm for quantum annealers. In a second phase the PhD activity will extend to optimization of more general target functions and also towards data representation into the quantum annealer for data-driven computation.
The candidate should be familiar with:
- Programming (Python experience preferred);
- Linear algebra;
- Algorithm Theory.
Experience in the following areas would also be useful, but can be acquired as part of the PhD:
- Quantum Computing (especially pertaining quantum annealing);
- Optimization algorithms (particularly tabu-search);
- Quantum Mechanics;
- Ising model.

A4 - Human behavior understanding and prediction (1 grant) [additional reserved topic scholarship

The project plans to investigate modern machine learning approaches for behavior analysis in video and event prediction. Specifically, the project will cover two significant computer vision topics, i.e., video-surveillance in urban scenarios and behavior understanding of people during a museum visit. We believe that the effort in computer vision should go behind scene segmentation and target detection and tracking towards a predictive capability. As such the project will explore the capabilities of algorithms and novel solutions in visual artificial intelligence to predict different types of events. Moreover, the project will predict the effect of collaborative interactions between people and between people and the context in which the analysis is taking place. State-of-the-art deep networks, such as Generative Adversarial Networks, Recurrent Neural Networks and Autoregressive Autoencoders will be used together with standard Convolutional Networks in order to define an effective predictive visual intelligence for new images and temporal reasoning. The research will be supported by the Artificial Intelligence for Cultural Heritage (AI4CH) project as part of the joint Italo-Israeli laboratory financed by MAECI and by the PRIN 2017 PREVUE (PRediction of activities and Events by Vision in an Urban Environment) project (CUPn: E64I19001120001).

C2 - Default in contextualized knowledge representation (1 grant)

Representation of context has been one of the main approaches in the knowledge representation and reasoning area for the management of large knowledge bases: here, modelling and reasoning on knowledge is relativized with respect to the contexts (situations, set of hypothesis) in which it is supposed to hold. Introducing forms of non-monotonic and default reasoning in logic-based contextual frameworks is a challenging research issue which, in particular, plays a role in the propagation and inheritance (with overriding) of knowledge across hierarchies of contexts. The objective of this PhD will be to investigate the possibilities for extending the theory and implementation of the current methods for representing default information in contextual frameworks and explore their applications.

C3 - Formal and genetic methods for model-based testing of parameterized systems (1 grant)

Many moders software systems are highly parameterized in order to take into account various operational conditions. Testing such problem is extremely difficult, given the astronomic number of combinations corresponding to all the parameter assignments. The challenge is to maximize the coverage and the confidence provided by the generated test cases without incurring in the limitations deriving from the parameterization space. The thesis will investigate the definition of novel testing techniques starting from the integration genetic  algorithms for software testing and test case generation approaches based on formal methods.

C4 - Safety analysis for space and avionic systems and software (1 grant)

Space and avionic systems are reaching an unprecedented degree of complexity. The process of safety analysis attempts to characterize the likelyhood of faults and failures, and to assess the effectiveness of the adopted mitigation measures. Unfortunately, traditional techniques are becoming ineffective, unable to deal with large scale systems.
This thesis will investigate novel methods for safety analysis, based on the adotpion of formal models of system and software (nominal and faulty) behaviours. Particularly interesting are the analysis of iming aspects in the propagation of multiple faults to failures and errors, the ability to explain the causality of propagation, and the definition of techniques for on-the-fly fault detection, isolation and recovery policies.

C5 - Condition monitoring for predictive maintenance by integrating machine learning and background knowledge (1 grant)

The current trend of automation and data exchange in manufacturing technologies allows to gather huge amounts of information. One of the challenges is to assess the condition of an equipment and foresee a failure before it actually occurs, so that fine-tuned, predictive maintenance can be applied. Although machine learning techniques can be used to tackle this problem, a pure data-driven approach is bound to re-discovering background information that is already available, such as operation modes and procedures, failure modes, and maintenance records. The thesis will investigate the integration of symbolic background knowledge within modern machine learning approaches, in order reduce the training time and improve the accuracy of predictions.

D1 - Signal processing and Deep Learning approaches for computer assisted lung ultrasound imaging (1 grant)

Deep Learning approaches, powerful Big Data Analytics processes based on multi-layer neural networks, are gaining popularity even in the clinical imaging field, thanks to their excellent performances in processing and classification of medical imaging for diagnostic purposes.
So far, Deep learning approaches have been only marginally applied on ultrasound, despite its non-invasiveness, low cost, wide availability and extensive use in several clinical settings; all these advantages make ultrasound imaging particularly suitable for the definition and development of innovative diagnostic systems employable on large populations. Furthermore, Artificial Intelligence approaches may help to overcome the limitations of ultrasound imaging, such as the operator-dependency and the low reproducibility.
Lung ultrasound imaging shines among the others as a prime example of potential application of Deep Learning methods, given the artefactual nature of the diagnostic features and the lack of a model that is sufficiently accurate for the quantitative interpretation of the data.
In view of these considerations, the present project will be aimed at creating a multi-application platform which uses Deep Learning approaches for the processing and classification of ultrasound images characterizing different pathological conditions. Results will also be compared with state-of-art model based approaches and possibly explored for the definition of new models and image processing algorithms.
This platform will take as input ultrasound images acquired with different ultrasound modalities following acquisition protocols specifically defined for each application. The employment of Deep Learning techniques together with the definition of specific acquisition protocols is aimed at overcoming the ultrasound-related limitations (e.g. its strong operator-dependent nature) and the implementation of a precision medicine approach.
In conclusion, the proposed framework will represent a powerful tool to be used in clinical practice for addressing important clinical needs, facilitating prevention programs and diagnostic strategies which will turn out to be appropriated, safe and aimed at resources optimization.
