Texto completo da fonteAssessing the risk of musculoskeletal disorders in industrial environments is a challenging task, given the complexity of modern manufacturing processes. These environments include various factors influencing operator activity, such as organizational, managerial and environmental elements, as well as the pace of work. Assessing the physical constraints to which operators are subjected is crucial to preventing these disorders. Although many systems currently monitor operator movements and assess postural constraints to provide an overview of physical activity, they often fail to analyze the physical forces experienced or generated by the operator. Consequently, it is essential to quantify these forces in order to identify effort-related physical risk factors. However, conventional measurement methods are often complex, invasive and impractical in industrial environments. This thesis addresses these challenges by evaluating learning approaches for estimating physical stresses without resorting to invasive measurements, which is fundamental to improving ergonomic tools and practices. We began by comparing the accuracy and robustness of computer vision-based measurement systems for RULA assessment, focusing particularly on on-site ergonomic evaluations. Our analysis focused primarily on the evaluation of computer vision-based systems, including those with one or more cameras, using RGB or depth images, and systems that rely solely on visual data or incorporate wearable sensors (hybrid systems). Next, we developed and evaluated several learning architectures designed to emulate the inverse dynamics step in motion analysis. These predict joint torques from the operator’s skeletal data and the weight and mass of the load carried, thus offering a new alternative to classical inverse dynamics methods. Finally, we examined the generalizability of deep learningbased tools, such as OpenCap, in industrial tasks. Using fine-tuning - a common technique in deep learning for adapting models to new data sets with minimal samples - we sought to adapt OpenCap’s learning models to a new type of motion and a new set of markers

Texto completo da fonteThis thesis deals with the problem of modeling and estimation of high-dimensional MoE models, towards effective density estimation, prediction and clustering of such heterogeneous and high-dimensional data. We propose new strategies based on regularized maximum-likelihood estimation (MLE) of MoE models to overcome the limitations of standard methods, including MLE estimation with Expectation-Maximization (EM) algorithms, and to simultaneously perform feature selection so that sparse models are encouraged in such a high-dimensional setting. We first introduce a mixture-of-experts’ parameter estimation and variable selection methodology, based on l1 (lasso) regularizations and the EM framework, for regression and clustering suited to high-dimensional contexts. Then, we extend the method to regularized mixture of experts models for discrete data, including classification. We develop efficient algorithms to maximize the proposed l1 -penalized observed-data log-likelihood function. Our proposed strategies enjoy the efficient monotone maximization of the optimized criterion, and unlike previous approaches, they do not rely on approximations on the penalty functions, avoid matrix inversion, and exploit the efficiency of the coordinate ascent algorithm, particularly within the proximal Newton-based approach
