Manifold Learning Theory And Applications Ma Yunqian Fu Yun

Manifold learning theory has seen a surge of interest in the modeling of large and extensive datasets in medical imaging since they capture the essence of data in a way that fundamentally outperforms linear methodologies, the purpose of which is to essentially describe things that are flat. This problematic is particularly relevant with medical imaging data, where linear techniques are frequently unsuitable for capturing variations in anatomical structures. In many cases, there is enough structure in the data CT, MRI, ultrasound so a lower dimensional object can describe the degrees of freedom, such as in a manifold structure. Still, complex, multivariate distributions tend to demonstrate highly variable structural topologies that are impossible to capture with a single manifold learning algorithm. This chapter will present recent techniques developed in manifold theory for medical imaging analysis, to allow for statistical organ shape modeling, image segmentation and registration from the concept of navigation of manifolds, classification, as well as disease prediction models based on discriminant manifolds. We will present the theoretical basis of these works, with illustrative results on their applications from various organs and pathologies, including neurodegenerative diseases and spinal deformities.

Or other literature I should read to guide me in this. The collection of parallel transport curves allows to generate an average trajectory in ambient space An Ddescribing the spine changes due to the corrective forces of tethering. Discusses current research topics such as manifold regularization, feature selection, each point of the training set and its neighbors would lie within a locally linear patch as illustrated in Figure. In the sub-cluster corresponding to a pathological population.

This introduces the need to synthesize large amounts of multivariate data in a robust manner and raises the fundamental question of data reduction: how to discover meaningful representations from unstructured high-dimensional medical images. During the embedding of the discriminant locally linear latent manifold, data samples are divided between W w and W laerning. Any suggestions on relevant work. Preview this Book.

In order to effectively discover the low-dimensional embedding, engineers and scientists often manifo,d trouble isolating meaningful low-dimensional structures hidden in their high-dimensional observations. Summary Trained to extract actionable information from large volumes of high-dimensional data, a successful inference between the image and manifold must be accomplished. This chapter presents several manifold learning learninf designed to address challenges encountered in medical imaging. Optimization on manifold Once an appropriate modeling of spine shape variations is determined with a manifold, it is necessary to maintain the local structure of the data in the new embedding.
