Unsupervised Maximum Margin Feature Selection with Manifold Regularization
Feature selection plays a fundamental role in many pattern recognition problems. However, most efforts have been focused on the supervised scenario, while unsupervised feature s...

Polynomial time approximation schemes for dense instances of NP-hard problems
We present a unified framework for designing polynomial time approximation schemes (PTASs) for “dense” instances of many NP-hard optimization problems, including maximum cut,...

Implementing Bit-addressing with Specialization
General media-processing programs are easily expressed with bitaddressing and variable-sized bit-fields. But the natural implementation of bit-addressing relies on dynamic shift ...

Cold Boot Key Recovery by Solving Polynomial Systems with Noise
A method for extracting cryptographic key material from DRAM used in modern computers has been recently proposed in [9]; the technique was called Cold Boot attacks. When considerin...
