Using Rescue Points to Navigate Software Recovery

Stelios Sidiroglou, Oren Laadan, Angelos D. Keromytis, Jason Nieh
2007 2007 IEEE Symposium on Security and Privacy (SP '07)

Recovery of damped exponentials using structured low rank matrix completion [article]

Arvind Balachandrasekaran, Vincent Magnotta, Mathews Jacob
2017 arXiv   pre-print
Since the direct use of current low rank matrix recovery schemes to this problem is associated with high computational complexity and memory demand, we adopt an iterative re-weighted least squares (IRLS  ...  ) algorithm, which facilitates the exploitation of the convolutional structure of the matrix.  ...  To create the single channel data, we performed a principal component analysis (PCA) on the original multi-channel data and selected the most significant component to obtain a coil compressed data.  ...
