Minimax Lower Bounds on Dictionary Learning for Tensor Data
Zahra Shakeri, Waheed U. Bajwa, Anand D. Sarwate
This paper provides fundamental limits on the sample complexity of estimating dictionaries for tensor data. The specific focus of this work is on th-order tensor data and the ca…
Minimax Lower Bounds for Kronecker-Structured Dictionary Learning
Zahra Shakeri, Waheed U. Bajwa, Anand D. Sarwate
Dictionary learning is the problem of estimating the collection of atomic elements that provide a sparse representation of measured/collected signals or data. This paper finds fund…
Design and Analysis Framework for Sparse FIR Channel Shortening
Abubakr O. Al-Abbasi, Ridha Hamila, Waheed U. Bajwa +1
A major performance and complexity limitation in broadband communications is the long channel delay spread which results in a highly-frequency-selective channel frequency response.…
