Functional Learning

Functional learning focuses on developing methods to analyze and learn from data represented as functions, such as time series or images, rather than individual data points. Current research emphasizes neural network architectures, including autoencoders and gradient descent algorithms operating within reproducing kernel Hilbert spaces, to achieve nonlinear representation learning and improve the efficiency of functional data analysis. This field is significant because it enables more effective handling of complex, high-dimensional functional data, leading to advancements in diverse applications like materials science, signal processing, and machine learning model generalization.
