Dimensionality Reduction with Subspace Structure Preservation
Devansh Arpit, Ifeoma Nwogu, Venu Govindaraju
Modeling data as being sampled from a union of independent subspaces has been widely applied to a number of real world applications. However, dimensionality reduction approaches th…
Is Joint Training Better for Deep Auto-Encoders?
Yingbo Zhou, Devansh Arpit, Ifeoma Nwogu +1
Traditionally, when generative models of data are developed via deep architectures, greedy layer-wise pre-training is employed. In a well-trained model, the lower layer of the arch…
An Analysis of Random Projections in Cancelable Biometrics
Devansh Arpit, Ifeoma Nwogu, Gaurav Srivastava +1
With increasing concerns about security, the need for highly secure physical biometrics-based authentication systems utilizing \emph{cancelable biometric} technologies is on the ri…
