A Scalable Information Theoretic Approach to Distributed Robot Coordination
(2011-09-25)
This paper presents a scalable information theoretic approach to infer the state of an environment by distributively controlling robots equipped with sensors. The robots iteratively estimate the environment state using a ...
Kernels for Vector-Valued Functions: a Review
(2011-06-30)
Kernel methods are among the most popular techniques in machine learning. From a frequentist/discriminative perspective they play a central role in regularization theory as they provide a natural choice for the hypotheses ...
Approximations in the HMAX Model
(2011-04-14)
The HMAX model is a biologically motivated architecture for computer vision whose components are in close agreement with existing physiological evidence. The model is capable of achieving close to human level performance ...
Automatic Input Rectification
(MIT CSAIL, 2011-10-03)
We present a novel technique, automatic input rectification, and a prototype implementation called SOAP. SOAP learns a set of constraints characterizing typical inputs that an application is highly likely to process ...
Fast and Robust Pyramid-based Image Processing
(2011-11-15)
Multi-scale manipulations are central to image editing but they are also prone to halos. Achieving artifact-free results requires sophisticated edgeaware techniques and careful parameter tuning. These shortcomings were ...
Leader Election Using Loneliness Detection
(2011-10-12)
We consider the problem of leader election (LE) in single-hop radio networks with synchronized time slots for transmitting and receiving messages. We assume that the actual number n of processes is unknown, while the size ...
Vote the OS off your Core
(2011-07-27)
Recent trends in OS research have shown evidence that there are performance benefits to running OS services on different cores than the user applications that rely on them. We quantitatively evaluate this claim in terms ...
A Frequency Analysis of Monte-Carlo and other Numerical Integration Schemes
(2011-12-14)
The numerical calculation of integrals is central to many computer graphics algorithms such as Monte-Carlo Ray Tracing. We show that such methods can be studied using Fourier analysis. Numerical error is shown to correspond ...
Decomposing Broadcast Algorithms Using Abstract MAC Layers
(2011-02-23)
In much of the theoretical literature on global broadcast algorithms for wireless networks, issues of message dissemination are considered together with issues of contention management. This combination leads to complicated ...
A Software Approach to Unifying Multicore Caches
(2011-06-28)
Multicore chips will have large amounts of fast on-chip cache memory, along with relatively slow DRAM interfaces. The on-chip cache memory, however, will be fragmented and spread over the chip; this distributed arrangement ...
