  • LabelMe: a database and web-based tool for image annotation 
    Russell, Bryan C.; Torralba, Antonio; Murphy, Kevin P.; Freeman, William T. (2005-09-08)
    Research in object detection and recognition in cluttered scenes requires large image collections with ground truth labels. The labels should provide information about the object classes present in each image, as well as ...
  • Language and Compiler Support for Auto-Tuning Variable-Accuracy Algorithms 
    Ansel, Jason; Wong, Yee Lok; Chan, Cy; Olszewski, Marek; Edelman, Alan; Amarasinghe, Saman (2010-07-27)
    Approximating ideal program outputs is a common technique for solving computationally difficult problems, for adhering to processing or timing constraints, and for performance optimization in situations where perfect ...
  • Latent-Dynamic Discriminative Models for Continuous Gesture Recognition 
    Morency, Louis-Philippe; Quattoni, Ariadna; Darrell, Trevor (2007-01-07)
    Many problems in vision involve the prediction of a class label for each frame in an unsegmented sequence. In this paper we develop a discriminative framework for simultaneous sequence segmentation and labeling which can ...
  • Leader Election Using Loneliness Detection 
    Ghaffari, Mohsen; Lynch, Nancy; Sastry, Srikanth (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 ...
  • LEAP Scratchpads: Automatic Memory and Cache Management for Reconfigurable Logic [Extended Version] 
    Adler, Michael; Fleming, Kermin E.; Parashar, Angshuman; Pellauer, Michael; Emer, Joel (2010-11-23)
    Developers accelerating applications on FPGAs or other reconfigurable logic have nothing but raw memory devices in their standard toolkits. Each project typically includes tedious development of single-use memory management. ...
  • Learning a Dictionary of Shape-Components in Visual Cortex: Comparison with Neurons, Humans and Machines 
    Serre, Thomas (2006-04-25)
    In this thesis, I describe a quantitative model that accounts for the circuits and computations of the feedforward path of the ventral stream of visual cortex. This model is consistent with a general theory of visual ...
  • Learning and disrupting invariance in visual recognition 
    Isik, Leyla; Leibo, Joel Z; Poggio, Tomaso (2011-09-10)
    Learning by temporal association rules such as Foldiak's trace rule is an attractive hypothesis that explains the development of invariance in visual recognition. Consistent with these rules, several recent experiments ...
  • Learning and Invariance in a Family of Hierarchical Kernels 
    Wibisono, Andre; Bouvrie, Jake; Rosasco, Lorenzo; Poggio, Tomaso (2010-07-30)
    Understanding invariance and discrimination properties of hierarchical models is arguably the key to understanding how and why such models, of which the the mammalian visual system is one instance, can lead to good ...
  • Learning by Learning To Communicate 
    Beal, Jacob (2007-08-23)
    Human intelligence is a product of cooperation among many different specialists. Much of this cooperation must be learned, but we do not yet have a mechanism that explains how this might happen for the "high-level" agile ...
  • Learning Commonsense Categorical Knowledge in a Thread Memory System 
    Stamatoiu, Oana L. (2004-05-18)
    If we are to understand how we can build machines capable of broadpurpose learning and reasoning, we must first aim to build systemsthat can represent, acquire, and reason about the kinds of commonsenseknowledge that we ...
  • Learning complex cell invariance from natural videos: A plausibility proof 
    Masquelier, Timothee; Serre, Thomas; Thorpe, Simon; Poggio, Tomaso (2007-12-26)
    One of the most striking feature of the cortex is its ability to wire itself. Understanding how the visual cortex wires up through development and how visual experience refines connections into adulthood is a key question ...
  • Learning From Snapshot Examples 
    Beal, Jacob (2005-04-13)
    Examples are a powerful tool for teaching both humans and computers.In order to learn from examples, however, a student must first extractthe examples from its stream of perception. Snapshot learning is ageneral approach ...
  • Learning Generic Invariances in Object Recognition: Translation and Scale 
    Leibo, Joel Z; Mutch, Jim; Rosasco, Lorenzo; Ullman, Shimon; Poggio, Tomaso (2010-12-30)
    Invariance to various transformations is key to object recognition but existing definitions of invariance are somewhat confusing while discussions of invariance are often confused. In this report, we provide an operational ...
  • Learning Grammatical Models for Object Recognition 
    Aycinena, Meg; Kaelbling, Leslie Pack; Lozano-Perez, Tomas (2008-02-25)
    Many object recognition systems are limited by their inability to share common parts or structure among related object classes. This capability is desirable because it allows information about parts and relationships in ...
  • Learning object segmentation from video data 
    Ross, Michael G.; Kaelbling, Leslie Pack (2003-09-08)
    This memo describes the initial results of a project to create aself-supervised algorithm for learning object segmentation from videodata. Developmental psychology and computational experience havedemonstrated that the ...
  • Learning Semantic Scene Models by Trajectory Analysis 
    Wang, Xiaogang; Tieu, Kinh; Grimson, Eric (2006-02-10)
    In this paper, we describe an unsupervised learning framework to segment a scene into semantic regions and to build semantic scene models from long-term observations of moving objects in the scene. First, we introduce two ...
  • Learning Solutions of Similar Linear Programming Problems using Boosting Trees 
    Banerjee, Ashis Gopal; Roy, Nicholas (2010-09-18)
    In many optimization problems, similar linear programming (LP) problems occur in the nodes of the branch and bound trees that are used to solve integer (mixed or pure, deterministic or stochastic) programming problems. ...
  • Learning to Trade with Insider Information 
    Das, Sanmay (2005-10-07)
    This paper introduces algorithms for learning how to trade usinginsider (superior) information in Kyle's model of financial markets.Prior results in finance theory relied on the insider having perfectknowledge of the ...
  • Learning using the Born Rule 
    Wolf, Lior (2006-05-16)
    In Quantum Mechanics the transition from a deterministic descriptionto a probabilistic one is done using a simple rule termed the Bornrule. This rule states that the probability of an outcome ($a$)given a state ($\Psi$) ...
  • Learning with Matrix Factorizations 
    Srebro, Nathan (2004-11-22)
    Matrices that can be factored into a product of two simpler matricescan serve as a useful and often natural model in the analysis oftabulated or high-dimensional data. Models based on matrixfactorization (Factor Analysis, ...
