Multi-Target Prediction: A Unifying View on Problems and Methods

Multi-target prediction (MTP) is concerned with the simultaneous prediction of multiple target variables of diverse type. Due to its enormous application potential, it has developed into an active and rapidly expanding research field that combines several subfields of machine learning, including multivariate regression, multi-label classification, multi-task learning, dyadic prediction, zero-shot learning, network inference, and matrix completion. In this paper, we present a unifying view on MTP problems and methods. First, we formally discuss commonalities and differences between existing MTP problems. To this end, we introduce a general framework that covers the above subfields as special cases. As a second contribution, we provide a structured overview of MTP methods. This is accomplished by identifying a number of key properties, which distinguish such methods and determine their suitability for different types of problems. Finally, we also discuss a few challenges for future research

A comparison of the CAR and DAGAR spatial random effects models with an application to diabetics rate estimation in Belgium

When hierarchically modelling an epidemiological phenomenon on a finite collection of sites in space, one must always take a latent spatial effect into account in order to capture the correlation structure that links the phenomenon to the territory. In this work, we compare two autoregressive spatial models that can be used for this purpose: the classical CAR model and the more recent DAGAR model. Differently from the former, the latter has a desirable property: its ρ parameter can be naturally interpreted as the average neighbor pair correlation and, in addition, this parameter can be directly estimated when the effect is modelled using a DAGAR rather than a CAR structure. As an application, we model the diabetics rate in Belgium in 2014 and show the adequacy of these models in predicting the response variable when no covariates are available

A Statistical Approach to the Alignment of fMRI Data

Multi-subject functional Magnetic Resonance Image studies are critical. The anatomical and functional structure varies across subjects, so the image alignment is necessary. We define a probabilistic model to describe functional alignment. Imposing a prior distribution, as the matrix Fisher Von Mises distribution, of the orthogonal transformation parameter, the anatomical information is embedded in the estimation of the parameters, i.e., penalizing the combination of spatially distant voxels. Real applications show an improvement in the classification and interpretability of the results compared to various functional alignment methods

Hidden Strains: Understanding Schizophrenia's Impact on Families and Communities

"Hidden Strains: Understanding Schizophrenia's Impact on Families and Communities" examines the challenges family caregivers of schizophrenia patients face in Romania. This study uncovers the socio-economic burdens and limited psychiatric support, particularly in rural areas, compounded by societal stigma. A significant finding is the caregivers' knowledge gap about schizophrenia, underscoring the need for mental health education for early detection and stigma reduction. The research stresses the vital roles of family and community in schizophrenia care, advocating for more community resources. It introduces innovative care models like the "Open Dialogue Approach" from Scandinavia, suggesting solutions for Romania's mental health challenges. Broadening its view, "Hidden Strains" contrasts Romanian mental health issues with global trends, emphasizing the urgency of mental health reforms. Concluding with recommendations for worldwide application, this work offers insights for professionals, caregivers, and policymakers, and resonates universally despite its Romanian foundation
