Exit Time Analysis for Approximations of Gradient Descent Trajectories Around Saddle Points
Rishabh Dixit, Mert Gurbuzbalaban, Waheed U. Bajwa
This paper considers the problem of understanding the exit time for trajectories of gradient-related first-order methods from saddle neighborhoods under some initial boundary condi…
Scaling-up Distributed Processing of Data Streams for Machine Learning
Matthew Nokleby, Haroon Raja, Waheed U. Bajwa
Emerging applications of machine learning in numerous areas involve continuous gathering of and learning from streams of data. Real-time incorporation of streaming data into the le…
Learning Product Graphs Underlying Smooth Graph Signals
Muhammad Asad Lodhi, Waheed U. Bajwa
Real-world data is often times associated with irregular structures that can analytically be represented as graphs. Having access to this graph, which is sometimes trivially eviden…
Distributed Stochastic Algorithms for High-rate Streaming Principal Component Analysis
Haroon Raja, Waheed U. Bajwa
This paper considers the problem of estimating the principal eigenvector of a covariance matrix from independent and identically distributed data samples in streaming settings. The…
