VCODE: A Retargetable, Extensible, Very Fast Dynamic Code Generation System

by Dawson R. Engler
"... Dynamic code generation is the creation of executable code at runtime. Such “on-the-fly ” code generation is a powerful technique, enabling applications to use runtime information to improve performance by up to an order of magnitude [4, 8, 20, 22, 23]. Unfortunately, previous general-purpose dynami ..."

Technical update: Least-squares temporal difference learning

by Justin A. Boyan - Machine Learning , 2002
"... Abstract. TD(λ) is a popular family of algorithms for approximate policy evaluation in large MDPs. TD(λ) works by incrementally updating the value function after each observed transition. It has two major drawbacks: it may make inefficient use of data, and it requires the user to manually tune a ste ..."

stepsize schedule for good performance. For the case of linear value function approximations and λ = 0, the Least-Squares TD (LSTD) algorithm of Bradtke and Barto (1996, Machine learning, 22:1–3, 33–57) eliminates all stepsize parameters and improves data efficiency. This paper updates Bradtke and Barto’s

Whom You Know Matters: Venture Capital Networks and Investment Performance,

"... Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

an overview of network analysis techniques and discusses their implementation in the VC context. A simple example illustrating network analysis is presented in the Appendix. Section II describes our data. In Section III, we analyze the effect of VC networking on fund performance. Section IV examines

Analysis and Visualization of Single-Trial Event-Related Potentials

by Tzyy-Oing Jung, Scott Makeig, Marissa Westerfield, Jeanne Townsend, Eric Courchesne, Terrence J. Sejnowski - HUMAN BRAIN MAPPING 14:166–185 , 2001
"... In this study, alinear decomposition technique, independent component analysis (ICA), is applied to single-trial multichannel EEG data from event-related potential (ERP) experiments. Spatial filters derived by ICA blindly separate the input data into asum of temporally independent and spatially fixe ..."

The carbon balance of tropical, temperate and boreal forests.

by Y Malhi , D D Baldocchi , P G Jarvis , Rd6 - Plant Cell and Environment, , 1999
"... ABSTRACT Forest biomes are major reserves for terrestrial carbon, and major components of global primary productivity. The carbon balance of forests is determined by a number of component processes of carbon acquisition and carbon loss, and a small shift in the magnitude of these processes would ha ..."

changes in soil temperature. At the oak-hickory site in 1997, rates rose from a constant 1 g C m -2 d -1 to a steady 4 g C m -2 d -1 in the June-August period (slightly higher than the tropical rain forest), as the average daily soil temperature rose to approximately 22°C, before falling away again

Blind evaluation of nearest neighbor queries using space transformation to preserve location privacy

by Ali Khoshgozaran, Cyrus Shahabi - In SSTD’07
"... Abstract. In this paper we propose a fundamental approach to perform the class of Nearest Neighbor (NN) queries, the core class of queries used in many of the location-based services, without revealing the origin of the query in order to preserve the privacy of this information. The idea behind our ..."

accurately and more importantly prevent malicious use of transformed data by untrusted entities. Traditional encryption based techniques incur expensive O(n) computation cost (where n is the total number of points in space) and possibly logarithmic communication cost for resolving a KNN query

Efficient Discovery of Functional and Approximate Dependencies Using Partitions (Extended version)

by Ykä Huhtala, Yka Huhtala, Juha Kärkkäinen, Juha Karkkainen, Pasi Porkka, Pasi Porkka, Hannu Toivonen, Hannu Toivonen - In ICDE , 1997
"... Discovery of functional dependencies from relations has been identified as an important database analysis technique. In this paper, we present a new approach for finding functional dependencies from large databases, based on partitioning the set of rows with respect to their attribute values. The us ..."

Spatial Methods in Econometrics

by Daniela Gumprecht
"... In this talk I will give a brief overview of the characteristics of spatial data, why it is useful to use such data and how to use the information included in spatial data. The rst question to be answered is: how to detect spatial dependency and spatial autocorrelation in data? Such eects can be fo ..."

1Spatial Compressive Sensing for MIMO Radar

by Marco Rossi, Student Member, Er M. Haimovich, Yonina C. Eldar
"... Abstract—We study compressive sensing in the spatial domain to achieve target localization, specifically direction of arrival (DOA), using multiple-input multiple-output (MIMO) radar. A sparse localization framework is proposed for a MIMO array in which transmit and receive elements are placed at ra ..."
