Computation and Relaxation of Conditions for Equivalence between ` 1 and ` 0 Minimization ∗

• Yoav Sharon, John Wright, Yi Ma
• 2007

In this paper, we investigate the exact conditions under which the ` and ` minimizations arising in the context of sparse error correction or sparse signal reconstruction are equivalent. We present a… (More)

Minimum sum of distances estimator: Robustness and stability

• Yoav Sharon, John Wright, Yi Fei Ma
• American Control Conference
• 2009

We consider the problem of estimating a state x from noisy and corrupted linear measurements y = Ax + z + e, where z is a dense vector of small-magnitude noise and e is a relatively sparse vector… (More)

Near-field optical photomask repair with a femtosecond laser.

• Klony Lieberman, Yoav Shani, Irina Melnik, S Yoffe, Yoav Sharon
• Journal of microscopy
• 1999

We present a high-resolution near-field optical tool designed for repair of opaque defects in binary photomasks. Both instrument design and near-field imaging and patterning results will be… (More)
