Patch complexity, finite pixel correlations and optimal denoising
(2012-10-07)
Image restoration tasks are ill-posed problems, typically solved withpriors. Since the optimal prior is the exact unknown density of natural images,actual priors are only approximate and typically restricted to small ...
Optimal Parametric Auctions
(2012-06-14)
We study the problem of an auctioneer who wants to maximize her profits. In our model, there are n buyers with private valuations drawn from independent distributions F_1,...,F_n. When these distributions are known to the ...
Integrated Robot Task and Motion Planning in the Now
(2012-06-29)
This paper provides an approach to integrating geometric motion planning with logical task planning for long-horizon tasks in domains with many objects. We propose a tight integration between the logical and geometric ...
Kintinuous: Spatially Extended KinectFusion
(2012-07-19)
In this paper we present an extension to the KinectFusion algorithm that permits dense mesh-based mapping of extended scale environments in real-time. This is achieved through (i) altering the original algorithm such that ...
Throwing Down the Visual Intelligence Gauntlet
(2012)
In recent years, scientific and technological advances have produced artificial systems that have matched or surpassed human capabilities in narrow domains such as face detection and optical character recognition. However, ...
Integrated robot task and motion planning in belief space
(2012-07-03)
In this paper, we describe an integrated strategy for planning, perception, state-estimation and action in complex mobile manipulation domains. The strategy is based on planning in the belief space of probability distribution ...
Viewstamped Replication Revisited
(2012-07-23)
This paper presents an updated version of Viewstamped Replication, a replication technique that handles failures in which nodes crash. It describes how client requests are handled, how the group reorganizes when a replica ...
The Levels of Understanding framework, revised
(2012-05-31)
I discuss the "levels of understanding" framework described in Marr's Vision and propose a revised and updated version of it to capture the changes in computation and neuroscience over the last 30 years.
Cicada: Predictive Guarantees for Cloud Network Bandwidth
(2014-03-24)
In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost. Most previous work on cloud-bandwidth guarantees has assumed that cloud tenants know ...
One Clock to Rule Them All: A Primitive for Distributed Wireless Protocols at the Physical Layer
(2014-04-27)
Implementing distributed wireless protocols at the physical layer today is challenging because different nodes have different clocks, each of which has slightly different frequencies. This causes the nodes to have frequency ...
