Iterative Projection Methods for Structured Sparsity Regularization
(2009-10-14)
In this paper we propose a general framework to characterize and solve the optimization problems underlying a large class of sparsity based regularization algorithms. More precisely, we study the minimization of learning ...
Code for LOLCAT Method (Variant of Gillespie Algorithm)
(2009-09-04)
This code and data is publicly listed code for the LOLCAT Method developed by Sagar Indurkhya and Jacob Beal, in the paper: "Reaction factoring and bipartite update graphs accelerate the Gillespie algorithm for large-scale ...
Attentive processing improves object recognition
(2009-10-02)
The human visual system can recognize several thousand object categories irrespective of their position and size. This combination of selectivity and invariance is built up gradually across several stages of visual processing. ...
Notes on the Shannon Entropy of the Neural Response
(2009-10-09)
In these notes we focus on the concept of Shannon entropy in an attempt to provide a systematic way of assessing the discrimination properties of the neural response, and quantifying the role played by the number of layers ...
Finding aircraft collision-avoidance strategies using policy search methods
(2009-09-12)
A progress report describing the application of policy gradient and policy search by dynamic programming methods to an aircraft collision avoidance problem inspired by the requirements of next-generation TCAS.
A Tour of MOOS-IvP Autonomy Software Modules
(2009-02-13)
This paper provides an overview of the MOOS-IvP autonomy software modules. The MOOS-IvP collection of software, i.e., codebase, described here has been developed and is currently maintained by three organizations - Oxford ...
Self-Stabilizing Message Routing in Mobile ad hoc Networks
(2009-01-28)
We present a self-stabilizing algorithm for routing messages between arbitrary pairs of nodes in a mobile ad hoc network. Our algorithm assumes the availability of a reliable GPS service, which supplies mobile nodes with ...
SoftCast: One Video to Serve All Wireless Receivers
(2009-02-07)
The main challenge in wireless video multicast is to scalably serve multiple receivers who have different channel characteristics. Current wireless transmission schemes, however, cannot support smooth degradation. Specifically, ...
Overcoming the Antennas-Per-Node Throughput Limit in MIMO LANs
(2009-02-18)
Today, the number of concurrent packets in a MIMO LAN is limited by the number of antennas on the AP. This paper shows how to overcome this limit. It presents a new design where multiple client-AP pairs can communicate ...
HAMPI: A Solver for String Constraints
(2009-02-04)
Many automatic testing, analysis, and verification techniques for programs can be effectively reduced to a constraint-generation phase followed by a constraint-solving phase. This separation of concerns often leads to more ...
