On measuring the accuracy of SLAM algorithms

In this paper, we address the problem of creating an objective benchmark for evaluating SLAM approaches. We propose a framework for analyzing the results of a SLAM approach based on a metric for measuring the error of the corrected trajectory. This metric uses only relative relations between poses and does not rely on a global reference frame. This overcomes serious shortcomings of approaches using a global reference frame to compute the error. Our method furthermore allows us to compare SLAM approaches that use different estimation techniques or different sensor modalities since all computations are made based on the corrected trajectory of the robot. We provide sets of relative relations needed to compute our metric for an extensive set of datasets frequently used in the robotics community. The relations have been obtained by manually matching laser-range observations to avoid the errors caused by matching algorithms. Our benchmark framework allows the user to easily analyze and objectively compare different SLAM approaches.     

Deadline-Oriented Servicing: Waiting-Time Distributions

An infinite queue single server model is considered where requests arrive from independent Poisson streams and demand service according to arbitrary distribution functions which may be different for different requests. Associated with each request is an urgency number which, together with request's time of arrival, defines a deadline for beginning its service. This relative urgency discipline has at its two limiting case the fint-come first-serve and head of the line discipline. In [1] the mean waiting time is computed approximately and dose bounds are derived there. Here we present simulation results, derive close approximations for the tails of the waiting-time distribution functions and compare them to those of the two limiting cases.     

Modelling experts' behavior with e-valUAM to measure computer science skills

In this work we present an evaluation method that focuses on experts' behavior instead of the traditional scores based just on the number of correct answers. The method presented here is especially suitable to measure the skills in Computer Science since this is a wide discipline very difficult to evaluate due to the many facts publicly available on the Internet. By using traditional evaluation tools, it is very difficult to measure the real knowledge of the users since they can correctly answer even without having acquired formal academic knowledge. To use this method, we have developed a test that can detect significant differences between standard users and experts in Computer Science. The test is applied by the e-valUAM application, which has been modified to store several parameters from the users' answers. By optimizing the parameters by a linear model, we have developed an equation that can be used to quantitatively compare the results of a single user with the results from the reference group of experts. This optimization is only possible because this group shows good stability and gives statistically different results compared to the other groups. The scores achieved with our method can be used to predict the formal knowledge of the users and modify their training when needed.

Evaluating Pervasive and Ubiquitous Systems

Recognized evaluation strategies are essential to systematically advance a research field's state of the art. Pervasive and ubiquitous computing need such strategies to mature as a discipline and to enable researchers to objectively assess and compare new techniques' contributions. Researchers have shown that evaluating ubiquitous systems can be difficult, so approaches tend to be subjective, piecemeal, or both. To ensure that the validity and usability of proposed systems won't be compromised, researchers must reach consensus on a set of standard evaluation methods for ubiquitous systems. Otherwise, methods for scientifically testing and presenting state-of-the-art advances will remain unclear. In this article, the organizers from four different workshop series, each focused on this topic, summarize and discuss the main outcomes of these events.     

On priority queues with priority jumps

In this paper, we investigate a simplified head-of-the-line with priority jumps (HOL-PJ) scheduling discipline. Therefore, we consider a discrete-time single-server queueing system with two priority queues of infinite capacity and with a newly introduced HOL-PJ priority scheme. We derive expressions for the probability generating function of the system contents and the packet delay. Some performance measures (such as mean and variance) of these quantities are derived and are used to illustrate the impact and significance of the HOL-PJ priority scheduling discipline in an output queueing switch. We compare this dynamic priority scheduling discipline with a first-in, first-out (FIFO) scheduling and a static priority scheduling (HOL) and we investigate the influence of the different parameters of the simplified HOL-PJ scheduling discipline.

Evolving structural design solutions using an implicit redundant Genetic Algorithm

Performing synthesis during conceptual design provides substantial cost savings by selecting an efficient design topology and geometry, in addition to selecting the structural member properties. A new evolutionary-based representation, which combines redundancy and implicit fitness constraints, is introduced to represent and search for design solutions in an unstructured, multi-objective structural frame problem. The implicit redundant representation genetic algorithm, in tandem with the unstructured problem domain definition, allows the evaluation of diverse frame topologies and geometries. The IRR GA allows the representation of a variable number of location independent parameters, which overcomes the fixed parameter limitations of standard GAs. The novel frame designs evolved by the IRR GA synthesis design method compare favourably with traditional frame design solutions calculated by trial and error. Received May 27, 1999
