Exploring the Space of Black-box Attacks on Deep Neural Networks | Existing black-box attacks on deep neural networks (DNNs) so far have largely
focused on transferability, where an adversarial instance generated for a

Convergence diagnostics for stochastic gradient descent with constant step size | Many iterative procedures in stochastic optimization exhibit a transient
phase followed by a stationary phase. During the transient phase the procedure

Data-Driven Sparse Sensor Placement for Reconstruction | Optimal sensor placement is a central challenge in the design, prediction,
