Real-time shadows for animated crowds in virtual cities
Authors: Céline Loscos, Franco Tecchia, Yiorgos Chrysanthou
Venue: Proceedings of the ACM symposium on Virtual reality software and technology (2001)

In this paper, we address the problem of shadow computation for large environments including thousands of dynamic objects. The method we propose is based on the assumption that the environment is 2.5D, which is often the case for virtual cities, thus avoiding complex visibility computation. We apply our method for virtual cities populated by thousands of walking humans, which we render with impostors, allowing real time simulation.In this paper, we treat the cases of shadows cast by buildings on humans, and by humans on the ground. To avoid 3D computation, we represent the shadows cast by buildings onto the environment with a 2.5D shadow map. When humans move, we quickly access the shadow information at the current location with a 2D grid. For each new position of a human, we compute its coverage by the shadow, and we render the shadow on top of the impostor with low cost using multi-texturing hardware. We also use the property of an impostor to display the shadow of humans on the ground plane, by projecting the impostor relatively to the light source.The method is currently limited to sharp shadows and a single light source. However approximations could be made to allow non-accurate soft-shadows. We show in the results that the computation of the shadows, as well as the display is done in real time, and that the method could be easily extended to real time moving light sources.
A statistical correlation model for image retrieval
Authors: Mingjing Li, Zheng Chen, Liu Wenyin, Hong-Jiang Zhang
Venue: Proceedings of the 2001 ACM workshops on Multimedia: multimedia information retrieval (2001)

A bigram correlation model for image retrieval is proposed, which captures the semantic relationship among images in a database from simple statistics of users' relevance feedback information. It is used in the post-processing of image retrieval results such that more semantically related images are returned to the user. The algorithm is easy to implement and can be efficiently integrated into an image retrieval system to help improve the retrieval performance. Preliminary experimental results on a database of 100,000 images are very promising.

Probabilistic query models for transaction data
Authors: Dmitry Pavlov, Padhraic Smyth
Venue: Proceedings of the seventh ACM SIGKDD international conference on Knowledge discovery and data mining (2001)

We investigate the application of Bayesian networks, Markov random fields, and mixture models to the problem of query answering for transaction data sets. We formulate two versions of the querying problem: the query selectivity estimation (i.e., finding exact counts for tuples in a data set) and the query generalization problem (i.e., computing the probability that a tuple will occur in new data). We show that frequent itemsets are useful for reducing the original data to a compressed representation and introduce a method to store them using an ADTree data structure. In an extension of our earlier work on this topic we propose several new schemes for query answering based on the compressed representation that avoid direct scans of the data at query time. Experimental results on real-world transaction data sets provide insights into various tradeoffs involving the offline time for model-building, the online time for query-answering, the memory footprint of the compressed data, and the accuracy of the estimate provided to the query.

The nonapproximability of OBDD minimization
Authors: Detlef Sieling
Venue: Information and Computation (2002)

The size of ordered binary decision diagrams (OBDDs) is determined by the chosen variable ordering. A poor choice may cause an OBDD to be too large to fit into the available memory. The decision variant of the variable ordering problem is known to be NP-complete. We strengthen this result by showing that, unless P=NP, for each constant c>1 there is no polynomial time approximation algorithm with the performance ratio c for the variable ordering problem, i.e., no polynomial time algorithm that guarantees the computation of a variable ordering so that the resulting OBDD size is larger than the minimum size by a factor of at most c. This result justifies, also from a theoretical point of view, the use of heuristics for the variable ordering problem.

Improved implementations of binary universal operations
Authors: Hagit Attiya, Eyal Dagan
Venue: Journal of the ACM (JACM) (2001)

We present an algorithm for implementing binary operations (of any type) from unary load-linked (LL) and store-conditional (SC) operations. The performance of the algorithm is evaluated according to its sensitivity, measuring the distance between operations in the graph induced by conflicts, which guarantees that they do not influence the step complexity of each other. The sensitivity of our implementation is O(log&ast; n), where n is the number of processors in the system. That is, operations that are &Omega;(log&ast; n) apart in the graph induced by conflicts do not delay each other. Constant sensitivity is achieved for operations used to implement heaps and array-based linked lists.We also prove that there is a problem which can be solved in O(1) steps using binary LL/SC operations, but requires O(log log&ast; n) operations if only unary LL/SC operations are used. This indicates a non-constant gap between unary and binary, LL/SC operations.
Automatic partitioning and virtual scheduling for efficient parallel execution
Authors: C. L. McCreary, D. H. Gill
Venue: Proceedings of the 30th annual Southeast regional conference (1992)

The research of this report gives a method for automatic determination and scheduling of parallel modules from an existing sequential computation.In compiling a sequential program for execution on a multiprocessor system, there are four major problems to be solved: [26]1. Analyzing the data dependences and control dependences in the program.2. Identifying parallelism in the program.3. Partitioning the program into grains of sequential tasks.4. Scheduling the tasks on processors.The work of this paper addresses the last three problems. The automatic dependence analysis, the phase that detects where parallelism is constrained, has been studied extensively, and there exist a number of tools (e.g. PAT[3], PTOOL[2], Parafrase[21], Faust[19] and PTRAN[1]) that create data flow and control flow graphs from sequential code. A directed graph is typically used to model the dependence relation. Usually, a node of the graph G = (N,E) represents an operation such as a statement or block of statements, and an edge (u,v) represents the dependence of v on u, forcing the execution of u before v. For both data and control dependence, the key is to represent only essential dependence constraints as edges. This paper assumes that a dependence graph exists and discusses a method for performing the last three tasks on the dependence graph. The technique decomposes the data flow graph into grains of the appropriate size for any underlying homogeneous multiprocessor architecture, determines which grains should be executed in parallel and which must be executed sequentially, and schedules those grains onto processors.
Facilitating knowledge flow through the enterprise
Authors: Jeanette Bruno
Venue: Proceedings of the tenth international conference on Information and knowledge management (2001)

This paper is concerned with the issues we encountered when attempting to achieve enterprise level knowledge reuse. We present 3 pilot studies where new visualization techniques were used to allow manufacturing and service operations take advantage of engineering knowledge embodied in 3D models. Though all these studies showed dramatic productivity increases, only one business unit from the studies is currently working to achieve the reuse. There are a number of reasons why this is so, but the key underlying theme is a lack of enterprise level commitment to knowledge sharing and a lack of an adequate knowledge architecture for sharing knowledge across organizational boundaries. We conclude with an approach for facilitating knowledge flow across functional units.

Similarity estimation techniques from rounding algorithms
Authors: Moses S. Charikar
Venue: Proceedings of the thiry-fourth annual ACM symposium on Theory of computing (2002)

(MATH) A locality sensitive hashing scheme is a distribution on a family $\F$ of hash functions operating on a collection of objects, such that for two objects x,y, Prh&egr;F[h(x) = h(y)] = sim(x,y), where sim(x,y) &egr; [0,1] is some similarity function defined on the collection of objects. Such a scheme leads to a compact representation of objects so that similarity of objects can be estimated from their compact sketches, and also leads to efficient algorithms for approximate nearest neighbor search and clustering. Min-wise independent permutations provide an elegant construction of such a locality sensitive hashing scheme for a collection of subsets with the set similarity measure sim(A,B) = \frac{|A &Pgr; B|}{|A &Pgr B|}.(MATH) We show that rounding algorithms for LPs and SDPs used in the context of approximation algorithms can be viewed as locality sensitive hashing schemes for several interesting collections of objects. Based on this insight, we construct new locality sensitive hashing schemes for:<ol>A collection of vectors with the distance between &rarr; \over u and &rarr; \over v measured by &Oslash;(&rarr; \over u, &rarr; \over v)/&pgr;, where &Oslash;(&rarr; \over u, &rarr; \over v) is the angle between &rarr; \over u) and &rarr; \over v). This yields a sketching scheme for estimating the cosine similarity measure between two vectors, as well as a simple alternative to minwise independent permutations for estimating set similarity.A collection of distributions on n points in a metric space, with distance between distributions measured by the Earth Mover Distance (EMD), (a popular distance measure in graphics and vision).

A study on the protection of statistical data bases
Authors: C. T. Yu, F. Y. Chin
Venue: Proceedings of the 1977 ACM SIGMOD international conference on Management of data (1977)

We study a number of protection schemes with respect to their effectiveness in providing security for statistical data bases, their feasibility and their ease of implementation. A new method is proposed, and two implementations presented. One implementation guarantees perfect protection against leakage of information about individuals; the other requires very little implementation effort, but has a small probability of leakage.
