Real-time learning and control using asynchronous dynamic programming by Andrew Gehret Barto( Book )

1 edition published in 1991 in English and held by 3 WorldCat member libraries worldwide

Abstract: "Learning methods based on dynamic programming (DP) are receiving increasing attention in artificial intelligence. Researchers have argued that DP provides the appropriate basis for compiling planning results into reactive strategies for real-time control, as well as for learning such strategies when the system being controlled is incompletely known. We extend the existing theory of DP-based learning algorithms by bringing to bear on their analysis a collection of relevant mathematical results from the theory of asynchronous DP. We present convergence results for a class of DP-based algorithms for real-time learning and control which generalizes Korf's Learning-Real-Time-A* (LRTA*) algorithm to problems involving uncertainty

Automated constrained expression analysis of real-time software( Book )

1 edition published in 1990 in English and held by 3 WorldCat member libraries worldwide

In this paper, we give a brief overview of our constrained expression formalism, analysis techniques and toolset, and then describe the modifications required to apply them to the analysis of timing properties. To illustrate the potential utility of our approach, we present an example analysis of a real-time problem carried out using the toolset. Finally, we discuss additional steps that may lead to increased capabilities for analyzing real-time software using constrained expression techniques."

Stochastic scheduling in in-forest networks by Z Liu( Book )

1 edition published in 1992 in English and held by 2 WorldCat member libraries worldwide

Abstract: "In this paper we study the extremal properties of several scheduling policies in a queueing network consisting of multi- server queues where the topology is that of an in-forest. Associated with each customer is a due date. We assume that service times at the different queues form mutually independent sequences of independent and identically distributed random variables independent of the arrival times and due dates. Furthermore, the network is assumed to consist of a mixture of nodes, some of which only permit non-preemptive service policies whereas the others permit preemptive resume policies
Fusing structure by Kalman filtering by J. Inigo Thomas( Book )

1 edition published in 1990 in English and held by 2 WorldCat member libraries worldwide

Abstract: "Deriving structure of the environment from motion using two successive images is error prone. However, if there are many measurements, they can be fused such that the reliability of the fused estimate is higher than for each of the noisy estimates. In a probabilistic framework, if the noise is assumed to be Gaussian, then reliability of each measurement is inversely proportional to the variance of its noise. Kalman filtering can be employed to combine noisy measurements such that the variance of the fused estimate is minimum
Scheduling a sequence of parallel programs containing loops within a centralized parallel processing system by Zhen Liu( Book )

Stronger optimality results on the minimization of job response time are obtained for a simpler job model."
Rationale for a heterogeneous parallel image understanding architecture by Chip Weems( Book )

1 edition published in 1990 in English and held by 2 WorldCat member libraries worldwide

Distinctly different forms of parallel processing can be applied at three levels of computational granularity, corresponding to levels of abstraction in the image interpretation process. Each level has its own unique computation, communication, and control requirements. In addition, interaction between levels must take place via parallel data and control paths. The paper concludes with an overview of the Image Understanding Architecture (IUA), a multilevel parallel processor designed to meet the requirements of image understanding. A proof-of-concept prototype of 1/64th of the IUA is currently being constructed by the University of Massachusetts and Hughes Research Laboratories."
Experimental evaluation of real-time optimistic concurrency control schemes( Book )

1 edition published in 1991 in English and held by 2 WorldCat member libraries worldwide

Through experiments, we investige, in depth, the effect of the locking mechanism on the performance of optimistic concurrency control protocols. We show that due to blocking, the performance of the protocols is sensitive to priority inversions but not to resource utilization. Further, in contrast to recent simulation studies, our experimental results show that with respect to meeting transaction deadlines, the optimistic approach may not always outperform the two-phase locking scheme which aborts the lower priority transaction to resolve a conflict. We also show that integrated with a weighted priority scheduling algorithm, optimistic concurrency control exhibits greater flexibility in coping with the starvation problem (for longer transactions) than two-phase locking
The Spring Kernel : a new paradigm for next generation real- time systems by John A Stankovic( Book )

1 edition published in 1991 in English and held by 2 WorldCat member libraries worldwide

Abstract: "Next generation, critical, hard real-time systems will require greater flexibility, dependability, and predictability than is commonly found in today's systems. These future systems include the space station, integrated vision/robotics/AI systems, collections of humans/robots coordinating to achieve common objectives (usually in hazardous environments such as undersea exploration or chemical plants), and various command and control applications. The Spring Kernel is an experimental and research oriented kernel designed to form the basis of a flexible, hard real-time operating system for such complex applications
Voice communication across the Internet : a network voice terminal by Henning Schulzrinne( Book )

1 edition published in 1992 in English and held by 2 WorldCat member libraries worldwide

Abstract: "Voice conferencing has attracted interest as a useful and viable first real-time application on the Internet. This report describes NEVOT a network voice terminal meant to support multiple concurrent both two-party and multi-party conferences on top of a variety of transport protocols and using audio encodings offering from vocoder to multi-channel CD quality. As it is to be used as an experimental tool, it offers extensive configuration, trace and statistics options. The design is kept modular so that additional audio encodings, transport and real- time protocols as well as user interfaces can be added readily. In the first part, the report describes the X-based graphical user interface, the configuration and operation
Multivariate versus univariate decision trees by Carla E Brodley( Book )

1 edition published in 1992 in English and held by 2 WorldCat member libraries worldwide

Abstract: "In this paper we present a new multivariate decision tree algorithm LMDT, which combines linear machines with decision trees. LMDT constructs each test in a decision tree by training a linear machine and then eliminating irrelevant and noisy variables in a controlled manner. To examine LMDT's ability to find good generalizations we present results for a variety of domains. We compare LMDT empirically to a univariate decision tree algorithm and observe that when multivariate tests are the appropriate bias for a given data set, LMDT finds small accurate trees."
