Deep Health Unit
Mission
The Deep Health Unit (DHU) is the research group oriented to the development of Artificial Intelligence (AI) pmodels and algorithms for decision support in the clinical field.
Bayesian probabilistic models, deep learning algorithms and ensemble algorithms are designed and developed for analysing multimodal data (structured tabular data, images, unstructured text, time series), even in large quantities, according to big data analytics approaches.
Areas of Interest
- Deep neural networks for:
- automatic extraction of features from multimodal imaging (AI-based biomarkers)
- development of decision support models in customised medicine (diagnostic and prognostic risk models)
- automatic segmentation of multimodal radiological images (MRI, CT, pet) for rapid and accurate extraction of quantitative clinical features
- Structuring of free texts from medical records in Italian, using Natural Language Processing (NLP) approaches
- Probabilistic programming for the implementation of Bayesian models
- Ensemble Algorithms
- Causal inference from observational data
Collaborations
The collaboration between DHU and the Epidemiology of the Institute of Clinical Physiology of the CNR led to the establishment of the DataLearnLab (D2L) laboratory.
