Approximate Extraction of Late-Time Returns via Morphological Component Analysis
Geoff Goehle, Benjamin Cowen, Thomas E. Blanford +2
A fundamental challenge in acoustic data processing is to separate a measured time series into relevant phenomenological components. A given measurement is typically assumed to be…
Enveloped Sinusoid Parseval Frames
Geoff Goehle, Benjamin Cowen, J. Daniel Park +1
This paper presents a method of constructing Parseval frames from any collection of complex envelopes. The resulting Enveloped Sinusoid Parseval (ESP) frames can represent a wide v…
Beyond Backprop: Online Alternating Minimization with Auxiliary Variables
Anna Choromanska, Benjamin Cowen, Sadhana Kumaravel +8
Despite significant recent advances in deep neural networks, training them remains a challenge due to the highly non-convex nature of the objective function. State-of-the-art metho…
LSALSA: Accelerated Source Separation via Learned Sparse Coding
Benjamin Cowen, Apoorva Nandini Saridena, Anna Choromanska
We propose an efficient algorithm for the generalized sparse coding (SC) inference problem. The proposed framework applies to both the single dictionary setting, where each data po…
