Course Syllabus
Aims
The goal of this class are:
- Knowledge and understanding
To provide students with an in-depth understanding of signal and imaging acquisition and analysis techniques relevant to environmental applications, with a focus on advanced methodologies such as remote sensing, hyperspectral imaging, and satellite or telescope-based observation systems.
- Applying knowledge and understanding
To enable students to apply signal and image processing techniques to high-resolution data acquired through complex remote sensing systems, and to extract meaningful features using state-of-the-art Machine Learning and Artificial Intelligence tools.
- Making judgements
To develop students’ ability to critically assess the quality and reliability of acquired environmental data, to select appropriate AI models and processing pipelines, and to interpret results in light of application-specific constraints and objectives.
- Communication skills
To enhance students’ capacity to effectively communicate complex signal and image analysis processes and results, through technical reports, visual presentations, and interdisciplinary collaboration, using appropriate terminology and data visualization tools.
- Learning skills
To foster autonomous learning in the rapidly evolving fields of environmental sensing, imaging technologies, and AI-based data analysis, enabling students to keep pace with emerging tools, methodologies, and scientific literature.
Contents
Basic theory of signal and imaging detectors, statistics and signal to noise ratio optimization, identification of sources and signals in noisy data. Analysis of time series and imaging data with ML methods (e.g. random forest classifier/regressors, self organizing maps, deep learning methods) using Python. Forecasts and tests of ML predictions.
Detailed program
- Operation and characterization of imaging detectors (focusing on optical CCDs), description of the calibrations needed.
- Characterization and description of other detectors for remote sensing of the environment.
- Statistics of photon counting experiments, noise and background sources, techniques for the detection of signals above the noise.
- Data handling packages in Python language, brief description of data visualization methods and ML implementations.
- Hands-on projects will be proposed where the students will learn how to extract relevant data and images from multi-petabyte catalogs and how to analyze them.
- Acquire imaging data from Bicocca Telescope and use ML with the aim to identify and characterize sources in the sky and the effects of light pollution.
