A Tractable Framework for Estimating and Combining Spectral Source Models for Audio Source Separation

Rémi Gribonval

The underdetermined blind audio source separation (BSS) problem is often addressed in the time-frequency (TF) domain assuming that each TF point is modeled as an independent random variable with sparse distribution. On the other hand, methods based on stru ...

Optimizing over the Growing Spectrahedron

Martin Jaggi

We devise a framework for computing an approximate solution path for an important class of parameterized semidefinite problems that is guaranteed to be ε-close to the exact solution path. The problem of computing the entire regularization path for matrix f ...

Rethinking FPGAs: Elude the Flexibility Excess of LUTs with And-Inverter Cones

Paolo Ienne, David Novo Bruna, Hadi Parandeh Afshar, Hind Benbihi

Look-Up Tables (LUTs) are universally used in FPGAs as the elementary logic blocks. They can implement any logic function and thus covering a circuit is a relatively straightforward problem. Naturally, flexibility comes at a price, and increasing the numbe ...

A Speculation-Friendly Binary Search Tree

Vincent Gramoli

We introduce the first binary search tree algorithm designed for speculative executions. Prior to this work, tree structures were mainly designed for their pessimistic (non-speculative) accesses to have a bounded complexity. Researchers tried to evaluate t ...

How to Allocate Tasks Asynchronously

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Asynchronous task allocation is a fundamental problem in distributed computing, in which p asyn- chronous processes must execute a set of m tasks. Also known as write-all or do-all, this problem been studied extensively, both independently and as a key bui ...

Complexity of the critical node problem over trees

Marco Di Summa

In this paper we deal with the critical node problem (CNP), i.e., the problem of searching for a given number K of nodes in a graph G, whose removal minimizes the (weighted or unweighted) number of connections between pairs of nodes in the residual graph. ...

On the Construction of Polar Codes

Emre Telatar, Seyed Hamed Hassani, Ramtin Pedarsani

We consider the problem of efficiently constructing polar codes over binary memoryless symmetric (BMS) channels. The complexity of designing polar codes via an exact evaluation of the polarized channels to find which ones are "good" appears to be exponenti ...

On The Power of Hardware Transactional Memory to Simplify Memory Management

Aleksandar Dragojevic

Dynamic memory management is a significant source of complexity in the design and implementation of practical concurrent data structures. We study how hardware transactional memory (HTM) can be used to simplify and streamline memory reclamation for such da ...

Sub-Logarithmic Test-and-Set Against a Weak Adversary

Dan Alistarh

A randomized implementation is given of a test-and-set register with O(log log it) individual step complexity and O(n) total step complexity against an oblivious adversary. The implementation is linearizable and multi-shot, and shows an exponential complex ...

Optimal-Time Adaptive Strong Renaming, with Applications to Counting

Seth Gilbert, Dan Alistarh, Morteza Zadimoghaddam

We give two new randomized algorithms for tight renaming, both of which work against an adaptive adversary. The first uses repeated sampling over a sequence of arrays of decreasing size to assign unique names to each of
