Cascading Regularized Classifiers
(2004-04-21)Among the various methods to combine classifiers, Boosting was originally thought as an stratagem to cascade pairs of classifiers through their disagreement. I recover the same idea from the work of Niyogi et al. to show ... -
The Case for a Factored Operating System (fos)
(2008-10-08)The next decade will afford us computer chips with 1,000 - 10,000 cores on a single piece of silicon. Contemporary operating systems have been designed to operate on a single core or small number of cores and hence are not ... -
A Case for Fine-Grain Adaptive Cache Coherence
(2012-05-22)As transistor density continues to grow geometrically, processor manufacturers are already able to place a hundred cores on a chip (e.g., Tilera TILE-Gx 100), with massive multicore chips on the horizon. Programmers now ... -
CG2Real: Improving the Realism of Computer Generated Images using a Large Collection of Photographs
(2009-07-15)Computer Graphics (CG) has achieved a high level of realism, producing strikingly vivid images. This realism, however, comes at the cost of long and often expensive manual modeling, and most often humans can still distinguish ... -
Characteristics of Small Social Networks
(2010-07-27)Two dozen networks are analyzed using three parameters that attempt to capture important properties of social networks: leadership L, member bonding B, and diversity of expertise D. The first two of these parameters have ... -
ChitChat: Making Video Chat Robust to Packet Loss
(2010-07-05)Video chat is increasingly popular among Internet users. Often, however, chatting sessions suffer from packet loss, which causes video outage and poor quality. Existing solutions however are unsatisfying. Retransmissions ... -
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 ... -
CNS: a GPU-based framework for simulating cortically-organized networks
(2010-02-26)Computational models whose organization is inspired by the cortex are increasing in both number and popularity. Current instances of such models include convolutional networks, HMAX, Hierarchical Temporal Memory, and deep ... -
Co-Clustering with Generative Models
(2009-11-03)In this paper, we present a generative model for co-clustering and develop algorithms based on the mean field approximation for the corresponding modeling problem. These algorithms can be viewed as generalizations of the ... -
Coded Emulation of Shared Atomic Memory for Message Passing Architectures
(2013-07-17)This paper considers the communication and storage costs of emulating atomic (linearizable) read/write shared memory in distributed message-passing systems. We analyze the costs of previously-proposed algorithms by Attiya, ... -
A Coded Shared Atomic Memory Algorithm for Message Passing Architectures
(2014-08-01)This paper considers the communication and storage costs of emulating atomic (linearizable) multi-writer multi-reader shared memory in distributed message-passing systems. The paper contains three main contributions: (1) ... -
Cognitive Security for Personal Devices
(2008-03-17)Humans should be able to think of computers as extensions of their body, as craftsmen do with their tools. Current security models, however, are too unlike those used in human minds---for example, computers authenticate ... -
Cognitive-Developmental Learning for a Humanoid Robot: A Caregiver's Gift
(2004-09-26)The goal of this work is to build a cognitive system for the humanoid robot, Cog, that exploits human caregivers as catalysts to perceive and learn about actions, objects, scenes, people, and the robot itself. This thesis ... -
CogSci to AI: It's the Brainware, Stupid!
(2006-03)Current modularization techniques fail when applied to hard AI problems.But cognitive science shows that the mind has modules specialized for particular functions.Unlike current engineered modules, the modules of themind ... -
Coherent Reaction
(2009-06-12)Side effects are both the essence and bane of imperative programming. The programmer must carefully coordinate actions to manage their side effects upon each other. Such coordination is complex, error-prone, and fragile. ... -
Collaborative Diagnosis of Over-Subscribed Temporal Plans
(2016-10-14)Over-subscription, that is, being assigned too many tasks or requirements that are too demanding, is commonly encountered in temporal planning problems. As human beings, we often want to do more than we can, ask for things ... -
Collective Choice with Uncertain Domain Moldels
(2005-08-16)When groups of individuals make choices among several alternatives, the most compelling social outcome is the Condorcet winner, namely the alternative beating all others in a pair-wise contest. Obviously the Condorcet ... -
Collusion-Resilient Revenue In Combinatorial Auctions
(2007-11-02)In auctions of a single good, the second-price mechanism achieves, in dominantstrategies, a revenue benchmark that is naturally high and resilient to anypossible collusion.We show how to achieve, to the maximum extent ... -
Collusive Dominant-Strategy Truthfulness
(2011-04-22)Fifty years ago, Vickrey published his famous mechanism for auctioning a single good in limited supply. The main property of Vickrey's mechanism is efficiency in dominant strategies. In absence of collusion, this is a ... -
Combined Static and Dynamic Mutability Analysis
(2007-03-23)Knowing which method parameters may be mutated during a method's execution is useful for many software engineering tasks. We present an approach to discovering parameter immutability, in which several lightweight, scalable ...
