A randomized protocol for signing contracts
, 1990
"... Two parties, A and B, want to sign a contract C over a communication network. To do so, they must “simultaneously” exchange their commitments to C. Since simultaneous exchange is usually impossible in practice, protocols are needed to approximate simultaneity by exchanging partial commitments in pie ..."

exchange probadilistic options for committing both parties to the contract; the protocol never terminates in an asymmetric situation where party A knows that party B is committed to the contract while he is not; the protocol makes use of a weak form of a third party (judge). If both A and B are honest
Fab: Content-based, collaborative recommendation
- Communications of the ACM
, 1997
"... Fab is a recommendation system designed to help users sift through the enormous amount of information available in the World Wide Web. Operational since Dec. 1994, this system combines the content-based and collaborative methods of recommendation in a way that exploits the advantages of the two appr ..."

for Computing Machinery Inc. By combining both collaborative and content-based filtering systems, Fab may eliminate many of the weaknesses found in each approach. Online readers are in need of tools to help them cope with the mass of content available on the World-Wide Web. In traditional media, readers
The design and implementation of an intentional naming system
- 17TH ACM SYMPOSIUM ON OPERATING SYSTEMS PRINCIPLES (SOSP '99) PUBLISHED AS OPERATING SYSTEMS REVIEW, 34(5):186--201, DEC. 1999
, 1999
"... This paper presents the design and implementation of the Intentional Naming System (INS), a resource discovery and service location system for dynamic and mobile networks of devices and computers. Such environments require a naming system that is (i) expressive, to describe and make requests based o ..."

Sparse coding with an overcomplete basis set: a strategy employed by V1
- Vision Research
, 1997
"... The spatial receptive fields of simple cells in mammalian striate cortex have been reasonably well described physiologically and can be characterized as being localized, oriented, and ban@ass, comparable with the basis functions of wavelet transforms. Previously, we have shown that these receptive f ..."

for representing a given input, and so the input-output function will deviate from being purely linear. These deviations from linearity provide a potential explanation for the weak forms of non-linearity observed in the response properties of cortical simple cells, and they further make predictions about
Weak Convergence And Optimal Scaling Of Random Walk Metropolis Algorithms
, 1994
"... This paper considers the problem of scaling the proposal distribution of a multidimensional random walk Metropolis algorithm, in order to maximize the efficiency of the algorithm. The main result is a weak convergence result as the dimension of a sequence of target densities, n, converges to infinit ..."

A new meshless local Petrov-Galerkin (MLPG) approach in computational mechanics
- Comput. Mech
, 1998
"... Abstract: A comparison study of the efficiency and ac-curacy of a variety of meshless trial and test functions is presented in this paper, based on the general concept of the meshless local Petrov-Galerkin (MLPG) method. 5 types of trial functions, and 6 types of test functions are explored. Differe ..."

. Different test functions result in different MLPG methods, and six such MLPG methods are pre-sented in this paper. In all these six MLPG methods, absolutely no meshes are needed either for the interpo-lation of the trial and test functions, or for the integration of the weak-form; while other meshless
Opinion observer: analyzing and comparing opinions on the web
- In WWW2005: the 4th international conference on World Wide Web, 2005
"... The Web has become an excellent source for gathering consumer opinions. There are now numerous Web sites containing such opinions, e.g., customer reviews of products, forums, discussion groups, and blogs. This paper focuses on online customer reviews of products. It makes two contributions. First, i ..."

The system is such that with a single glance of its visualization, the user is able to clearly see the strengths and weaknesses of each product
Constructing Biological Knowledge Bases by Extracting Information from Text Sources

However, information in text form, such as MEDLINE records, remains a greatly underutilized source of biological information. We have begun a research effort aimed at automatically mappi ..."

Exploiting Weak Connectivity for Mobile File Access

In this paper, we describe how the Coda File System has evolved to exploit such networks. The underlying theme of this evolution has been the systematic introduction of adaptiv ..."

FOIL: A Midterm Report
- In Proceedings of the European Conference on Machine Learning
, 1993
"... : FOIL is a learning system that constructs Horn clause programs from examples. This paper summarises the development of FOIL from 1989 up to early 1993 and evaluates its effectiveness on a non-trivial sequence of learning tasks taken from a Prolog programming text. Although many of these tasks ..."
