Sharp Reconstruction Bounds for Autoencoders Using the Same Forward Map
Patricia Medina, Hy P. G. Lam
We study reconstruction in autoencoders that apply the same forward map before and after setting the observed coordinates to zero. For equal odd input and hidden dimensions $d\geq…
Depth-Dependent Hidden-State Collapse in Dynamical System Autoencoders for LiDAR Point-Cloud Classification
Patricia Medina, Hy P. G. Lam
We study Dynamical System Autoencoders (DSAE) for LiDAR point-cloud classification using spatial coordinates and Product Coefficient feature augmentations. The experiments compare…
Integrating Product Coefficients for Improved 3D LiDAR Data Classification (Part II)
Patricia Medina, Rasika Karkare
This work extends our previous study on enhancing 3D LiDAR point-cloud classification with product coefficients \cite{medina2025integratingproductcoefficientsimproved}, measure-the…
Integrating Product Coefficients for Improved 3D LiDAR Data Classification
Patricia Medina
In this paper, we address the enhancement of classification accuracy for 3D point cloud Lidar data, an optical remote sensing technique that estimates the three-dimensional coordin…
