Application of state of the art DL models for the reconstruction and selection of events in high energy physics experiments:
Machine Learning is one of the fields of data analysis and computational research that has received greater interest and attention in recent years. "Multivariate Analysis", "(Deep) Neural Networks", "Advanced classification or pattern recognition techniques", "Clustering Algorithms" etc., are techniques belonging to a general class of machine learning algorithms that are able to solve in a very efficient and powerful way a great variety of problems in high energy physics ranging from the development of real-time data filter systems (trigger systems), to the offline reconstruction of events, to data analysis proper. Several thesis topics are proposed on the subject, both oriented to the development of new Deep-learning algorithms to be used in the trigger systems of the ATLAS experiment, and to the application of Deep-NeuralNetworks in classification, prediction, anomaly detection, and generative algorithms to be applied in search for new physics and / or precision measurements in the new high-energy and statistical data samples recorded by the ATLAS experiment during Run 2 of LHC and that are currently acquired in Run 3..

Development and study of the performances of novel algorithms on FPGAs for muon reconstruction and identification in the ATLAS L0 Muon Barrel Trigger
The Level-0 muon trigger system of the ATLAS experiment will undergo a full upgrade for the High Luminosity LHC to stand the challenging requirements imposed by the increase in instantaneous luminosity. The upgraded trigger system will send raw hit data to off-detector processors, where trigger algorithms run on a new generation of FPGAs. To exploit the flexibility provided by the FPGA systems, ATLAS is developing novel algorithms based on both conventional methods and new deep neural network architectures that use quantised weights and activations, optimised to run on FPGAs for efficient reconstruction and identification of muons in the ATLAS "Level-0" trigger. The FPGA represents an optimal solution in this context, because of its flexibility, wide availability of logical resources and high processing speed. In this context the student will work within the ATLAS L0 Muon Barrel trigger group, in the design and deployment of novel fast trigger algorithms based on state-of-the-art machine learning algorithms. The thesis work will include algorithm development and implementation and evaluation of physics performance in terms of efficiency and fake rates and FPGA logic resource occupancy and timing.

Study of novel Deep Graph Network and Transformers models for particle identification and particle flow in the IDEA dual readout calorimeter for future e+e- colliders
Dual-readout calorimetry has emerged as a technique for measuring the properties of high-energy hadrons and hadron jets that offers considerable advantages compared with the instruments that are currently used for this purpose in experiments at the high-energy frontier. The IDEA detector concept for future lepton colliders plan to use a dual-readout fibre calorimeter equipped with fast processors (FPGAs) that allows to implement advanced AI algorithms for reconstruction and particle flow analysis for offline and real-time environments (trigger). The student will work on the design and development of state of the art and novel Deep Learning algorithms based in geometrical deepl learning and in the performance assessment in the context of the identification of different decays of tau leptons and for the particle flow reconstruction. The research works may also includes study of the physics perfromance messured on different benchmark physics processes of interest for the FCCee accelerator program.

Study of single and di-Higgs production with the ATLAS experiment at LHC
According to the Standard Model, the Higgs boson can interact with itself, resulting in the simultaneous production of two Higgs bosons ("di-Higgs production"). This is expected to be a very rare process – so rare that, according to the Standard Model, physicists will need around 20 times more data than available today to be able to measure it. This will be possible with the High-Luminosity upgrade of the LHC. However, physics beyond the Standard Model may enhance the di-Higgs production rate, by altering the strength of the Higgs self-interaction or through an intermediate heavy particle. The thesis concerns the development and optimisation of a dedicated analysis for the channel HH->bbtautau based on the dataset that ATLAS is collecting in the just started Run-3 of the LHC machine. In this context different task are possible, ranging from data analysis and optmisation, to trigger studies, to development of machine learning tools.

Search for new physics in di-boson boosted jet topolgies with anomaly detection techniques in the ATLAS experiment
In recent years, there has been an explosion of applications of machine learning-based anomaly detection for New Physics searches, enabling the identification of out-of-distribution events that may signal new phenomena or deviations from the Standard Model in a signal-agnostic way. In this research we'll analyze Run-3 data collected by the ATLAS experiment in search for anomalous signature predicted by new physics in final states with multiple boosted jets. The thesis work includes both experimental analysis of collider detector data and the development of cuting-edge Deep Learning algorithms (GGN, Transformers) for Anomaly detection of fat hadronic jets.

Artificial Intelligence for non-linear spectroscopy (insieme al gruppo di spettroscopia Raman del Prof. T. Scopigno)
La spettroscopia Raman non-lineare è uno strumento potente in grado di indagare le proprietà vibrazionali della materia su scala atomica. Rispetto alla spettroscopia Raman convenzionale, presenta numerosi vantaggi, come la possibilità di mappare fenomeni ultraveloci e determinare il moto atomico su scale temporali del femtosecondo. Tuttavia, a causa della non linearità dei processi ottici su cui si basa, i segnali misurati sperimentalmente sono generalmente più complessi e difficili da interpretare: le forme di righe possono apparire sovrapposte ad un segnale di background e subire forti distorsioni, con profili spettrali che possono apparire sia negativi che dispersivi. La tesi ha carattere teorico-sperimentale, prevede infatti di sviluppare tramite algoritmi di Intelligenza Artificiale una Rete Neurale in grado di isolare il segnale Raman dai contributi non-lineari spuri. Gli algoritmi verranno allenati mediante opportuni training set ottenuti dal calcolo delle risposte Raman non-lineari per sistemi modello. Come benchmark per la validazione del protocollo sviluppato saranno utilizzati dati acquisiti sperimentalmente su sistemi reali

Studio di algoritmi di Deep Learning basati su Graph Neural Network per la classificazione e la ricomposizione di oggetti solidi divisi in frammenti (in collaborazione con l'opificio delle pietre dure di Firenze)
La ricostruzione di oggetti solidi divisi in frammenti o regioni di dimensioni e caratteristiche diverse è un problema non risolto da lungo tempo, che ha interessato le comunità di grafica computazionale, matematica, e più recentemente del machine learning. A differenza del caso 2D la complessità maggiore del caso 3D fa si che non esistano ad oggi tecniche generali consolidate per affrontare queste casistiche. Negli ultimi anni in particolare l’applicazione di algoritmi di deep learning a questi problemi su oggetti 3D ha portato a risultati significativi in campi molto diversi, che vanno dalla medicina, alla fisica fino all’ambito dei beni culturali. Si veda a tal proposito l’applicazione degli algoritmi di deep learning alla catena di ricostruzione dell’Esercito di Terracotta (inserito nell’elenco dei patrimoni dell’umanità dell’Unesco). Si propone una tesi di carattere teorico-sperimentale che prevede lo sviluppo di algoritmi innovativi di deep learning basati su Graph Neural Networks per la ricostruzione di un oggetto a partire dai suoi frammenti. In una prima fase verrà sviluppato il modello teorico, ed in seguito l’algoritmo verrà applicato ad uno o più casi reali nel contesto della ricostruzione di manufatti antichi.

Sviluppo di nuovi odelli basati su Graph Neural Network ispirati alla fisica per la soluzione di problemi di ottmizzazione combinatoriale (Graph Coloring, problemi sat, etc.)
The graph coloring problem is an optimization problem involving the assignment of one of q colors to each vertex of a graph such that no two adjacent vertices share the same color. This problem is NP-hard and arises in various practical applications. We'll develop and test novel algorithms that leverages graph neural networks to tackle the problem efficiently, particularly for large graphs. The approach is physics-inspired, an approach that leverages tools used in statistical mechanics to improve the training and performance of the algorithm

Sviluppo di nuovi modelli basati su Graph Neural Network basati su PU-learning per l'analisi di knowledge graph di grande dimensione
nderstanding and predicting relationships within complex systems is a key challenge across many disciplines. Systems like ecosystems, social networks, and climate models resist full characterization due to their complexity and numerous variables. When system dynamics and interactions between components are only partially understood, machine learning becomes a vital tool for uncovering patterns and hidden relationships from data. However, real-world datasets often face limited availability and high acquisition costs, capturing only a fraction of possible interactions. These datasets are also prone to sampling biases influenced by practical or economic constraints, leading to incomplete and non-i.i.d. (independent and identically distributed) data. This challenges traditional machine learning methods, which typically require complete and unbiased datasets. This thesis proposes developing algorithms that work without fully supervised data. The goal is to create a theoretical framework for machine learning methods that analyze complex systems with interactive components, even when data is biased and incomplete.
