2020 Lecture Notes in Computer Science  
Such a proposal relays on describing QoS contracts as convex specifications, and compliance checking is performed by the application of an analysis algorithm based on state of the art techniques used in  ...  While there is not much discussion on the importance of formally describing and analysing quantitative requirements in the process of software construction; in the paradigm of API-based software systems  ...  The next proposition provides upper bounds for the relative error that do not depend on the exact value v of the volume but on two consecutive approxima- tions: {v k−1 , v k } or {v k , v k+1 }.  ...

An empirical study of the effect of background data size on the stability of SHapley Additive exPlanations (SHAP) for deep learning models [article]

Han Yuan, Mingxuan Liu, Lican Kang, Chenkui Miao, Ying Wu
2022 arXiv   pre-print
Generally, a background dataset consists of instances randomly sampled from the training dataset. However, the sampling size and its effect on SHAP remain to be unexplored.  ...  Nowadays, the interpretation of why a machine learning (ML) model makes certain inferences is as crucial as the accuracy of such inferences.  ...  Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper  ...

Compositional solution space quantification for probabilistic software analysis

Mateus Borges, Antonio Filieri, Marcelo d'Amorim, Corina S. Păsăreanu, Willem Visser
2013 Proceedings of the 35th ACM SIGPLAN Conference on Programming Language Design and Implementation - PLDI '14  
Current approaches rely on symbolic execution to identify the conditions to reach the target event and try to quantify the fraction of the input domain satisfying these conditions.  ...  The approach leverages interval constraint propagation to improve the accuracy of the estimation by focusing the sampling on the regions of the input domain containing the sought solutions.  ...  This independence is straightforwardly 1 As support of this statement, notice that Pr(C i j |v k =v k 1 ) = Pr(C i j |v k = v k 2 ), where v k / ∈Ṽ j andv 1 k andv 2 k are any two valid assignments for  ...

On Presburger arithmetic extended with non-unary counting quantifiers [article]

Peter Habermehl
2022 arXiv   pre-print
This latter result almost matches Berman's exact complexity of first-order logic without counting quantifiers.  ...  The move from unary to non-unary quantifiers is non-trivial, since, e.g., the non-unary version of the H\"artig quantifier results in an undecidable theory.  ...  The authors thank Christian Schwarz from TU Ilmenau for proofreading the paper and for correcting two mistakes.  ...

Collisionless gas flows over a flat cryogenic pump plate

Chunpei Cai, Khaleel Khasawneh
2009 Journal of Vacuum Science & Technology. A. Vacuum, Surfaces, and Films  
At any point off the plate, the local velocity distribution function ͑VDF͒ consists of several pieces of Maxwellian VDFs, one is characterized by free stream flow properties and the others by plate surface  ...  We use these solutions to derive several useful expressions, based on special measured flow field properties at specific locations off the plate, to evaluate the pump sticking probability.  ...  The same grids are used for the DSMC simulations and evaluations of the exact solutions.  ...

Oracle Circuits for Branching-Time Model Checking [chapter]

Philippe Schnoebelen
2003 Lecture Notes in Computer Science  
This framework allows us to evaluate the precise computational complexity of model checking for some branching-time logics where it was known that the problem is NP-hard and coNP-hard.  ...  It is shown that they can be evaluated in deterministic polynomial-time with a polylog number of adaptive queries to an NP oracle.  ...  Our formulation quantifies upon indexes l 1 , . . . , l m in the 1, . . . , k range but such a l j is a shorthand for e.g. k bits "l j =1", . . . , "l j =k" among which one and only one will be true.  ...
