My lab works on a wide variety of problems at the interface of Statistics and Genetics. Survival Analysis. This is a desirable property for a neuroimaging statistic as it ensures that any signal processing or feature extraction applied to the recorded responses (for example spectral analysis) cannot artificially inflate the measured effect size, provided it is applied across the whole dataset without incorporating knowledge of the stimulus. Thus, much of our research involves developing new statistical methodology, many of which have a non. The application of deep learning (DL) models to neuroimaging data poses several challenges, due to the high dimensionality, low sample size, and complex temporo-spatial dependency structure of these data.

Learning Outcomes; The programme aims to contribute to improved understanding of the use of neuroimaging in research by users from a wide range of different disciplines, including understanding the principals of study design to avoid bias, practicalities and limitations of different imaging techniques, and image analysis processes. It aims at development and application of statistical methods and their interface with other quantitative methods, such as computational and mathematical methods, in biological and life science, health science, and biopharmaceutical and biotechnological science. Neuroimaging analysis of all these modalities has a long history of close relationship with data science, statistics, and medical imaging community. Neuroimaging data often take the form of high-dimensional arrays, also known as tensors. Simple models and algorithms based on restrictive assumptions are often used in the field of neuroimaging for studies involving functional magnetic resonance imaging, voxel based morphometry, and diffusion tensor imaging. Not so long ago, biomedical signal processing was limited to filtering, modelling or spectral analysis, prior to visual inspection. The platform is called Clinica and is targeting clinicians as well as researchers developing machine learning algorithms.
