Exploring Processes and Deviations

by Er J. J. Leemans, Dirk Fahl
"... Abstract In process mining, one of the main challenges is to discover a process model, while balancing several quality criteria. This often requires repeatedly set-ting parameters, discovering a map and evaluating it, which we refer to as process exploration. Commercial process mining tools like Dis ..."

Process and Deviation Exploration with Inductive visual Miner

by Er J. J. Leemans, Dirk Fahl
"... Abstract Process mining aims to extract information from recorded process data, which can be used to gain insights into the process. This requires applying a discovery algorithm and settings its parameters, after which the discovered process model should be evaluated. Both steps may need to be repea ..."

to be repeated several times until a satisfying model is found; we refer to this as process exploration. Existing commercial tools usually do not provide models having executable semantics, thereby disallowing for accurate map evaluation, while most academic tools lack features and by the repetitive nature

Data Caching Issues in an Information Retrieval System

by Rafael Alonso, Daniel Barbara, Hector Garcia-molina - ACM Transactions on Database Systems , 1990
"... Currently, a variety of information retrieval systems are available to potential users. These services are provided by commercial enterprises (such as Dow Jones [6] and The Source [7]), while others are research efforts (the Boston Community Information System [S]). While in many cases these systems ..."

these systems are accessed from personal computers, typically no advantage is taken of the computing resources of those machines (such as local processing and storage). In this paper we explore the possibility of using the user’s local storage capabilities to cache data at the user’s site. This would improve

How to Deal with Deviations during Process Model Enactment

by G. Cugola, E. Di Nitto, C. Ghezzi, E. Di, Nitto C. Ghezzi, M. Mantione - in Proceedings of the 17th International Conference on Software Engineering , 1995
"... A fundamental problem in software processes is how the intrinsic rigidity of a predefined (formal) model can be reconciled with the need for flexibility, change, and evolution. We therefore distinguish between software processes, as specified in a process description, and their actual performance by ..."

by humans. Further, we claim that the two inevitably diverge, and thus it is necessary to provide means to reconcile them. We present a preliminary exploration into the problem. In particular, we illustrate how a temporal logic-based approach can be used to capture and tolerate some deviations from

Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.

by Robert J Vallerand , Michelle S Fbrtier , Frederic Guay - Journal of Personality and Social Psychology, , 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

, especially as pertains to their antecedents and consequences. Finally, such a model, if proven valid, should provide a better understanding of the process involved in dropping out of high school, thereby leading to potential insights concerning future interventions with this population. Below, we present

Small Deviation Probability via Chaining

by Frank Aurzada , Mikhail Lifshits , 2008
"... We obtain several extensions of Talagrand’s lower bound for the small deviation probability using metric entropy. For Gaussian processes, our investigations are focused on processes with sub-polynomial and, respectively, exponential behaviour of covering numbers. The corresponding results are also p ..."

Inference with an incomplete model of english auctions

by Philip A. Haile, Elie Tamer - JOURNAL OF POLITICAL ECONOMY , 2003
"... While English auctions are the most common in practice, their rules typically lack sufficient structure to yield a tractable theoretical model without significant abstractions. Rather than relying on one stylized model to provide an exact interpretation of the data, we explore an incomplete model ba ..."

-gen-erating process deviates in seemingly small ways from that implied by equilibrium in the standard theoretical model, existing methods can yield misleading results that need not even lie within our bounds. We report results from Monte Carlo experiments illustrating the perform-ance of our approach and comparing

"... 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 ..."

SMALL DEVIATIONS FROM MAXIMIZING BEHAVIOR IN A SIMPLE DYNAMIC MODEL*

by Asher Wolinsky
"... The motivating intuition is that the presence of nonmaximizing agents induces maximizing agents to take advantage of them, and that this might magnify the effect of small deviations from maximizing behavior. This intuition is explored using a simple dynamic model. With an inflexible entry process, s ..."
