Deep Fréchet Neural Network Framework Proposed for Metric-Space-Valued Regression
Researchers introduce DFNN, a deep neural network framework designed for regression tasks where the response variable lies in a general metric space rather than Euclidean coordinates. The approach targets non-Euclidean outputs such as probability distributions, networks, symmetric positive-definite matrices, and compositional data. It extends Fréchet regression concepts into deep learning architectures for these increasingly common data types.
