Recognising the dynamic form of fire

Fintan Nagle, Alan Johnston
2021 Scientific Reports  
Increased errors with embedded sequence length were driven by positive responses to non-target sequences (false alarms) rather than omissions.  ...  We also suggest that prediction could provide a means of providing and evaluating evidence in a sequential analysis model.  ...  This sequential analysis approach also admits the occurrence of false positives for patterns that are similar to the target pattern, since it is stochastic and based on partial evidence.  ...

Integrating profile-driven parallelism detection and machine-learning-based mapping

Zheng Wang, Georgios Tournavitis, Björn Franke, Michael F. P. O'boyle
2014 ACM Transactions on Architecture and Code Optimization (TACO)  
Compiler-based auto-parallelization is a much studied area, but has yet to find wide-spread application.  ...  We have identified two weaknesses in traditional parallelizing compilers and propose a novel, integrated approach, resulting in significant performance improvements of the generated parallel code.  ...  Column 2 in table IV shows the number of loops our approach detects as potentially parallel. The column labeled FP ("false positive") shows how many of these were in fact sequential.  ...

2021 Bioinformatics  
This chapter is a survey of computational methods based on paired end reading, efficient search techniques and parallel computing to detect structural variants in both whole genome and transcriptome sequences  ...  Due to the massive amounts of data and the fact that structural variants account for just a small fraction of the data, efficient and accurate search methods are required for the detection of chromosomal  ...  It is possible to analyze the NGS data for the detection of boundaries of CNV regions on a chromosome or a genome by phrasing the problem as a statistical change point detection problem presented in the  ...

Chang-ai Sun, Yan Zhao, Lin Pan, Huai Liu, Tsong Yueh Chen
2018 IEEE Transactions on Services Computing  
The experimental results show that the automatic scenario-oriented testing approach is effective in detecting many types of faults seeded in the service compositions.  ...  In this paper, we propose a scenario-oriented testing approach that can automatically generate test cases for service compositions.  ...  The other metric, fault discovery rate, is also natural and straightforward to reflect how effective a test suite is in detecting a certain fault.  ...

A Review of Rule Learning Based Intrusion Detection Systems and Their Prospects in Smart Grids

Qi Liu, Veit Hagenmeyer, Hubert B. Keller
2021 IEEE Access  
Despite the fact that anomaly based IDS can detect novel attacks, they are not often deployed in industry, mainly owing to high false positive rate and lack of interpretability of trained models.  ...  With misuse based IDS' inability to detect unknown attacks and requirement for frequently manually crafting and updating signatures and with anomaly based IDS' bad reputation for high false alarm rate,  ...  The worst false positive rate is 4.2% while keeping a 100% detection rate.  ...

Saliency Detection: A Spectral Residual Approach

Xiaodi Hou, Liqing Zhang
2007 2007 IEEE Conference on Computer Vision and Pattern Recognition  
The ability of human visual system to detect visual saliency is extraordinarily fast and reliable. However, computational modeling of this basic intelligent behavior still remains a challenge.  ...  This paper presents a simple method for the visual saliency detection. Our model is independent of features, categories, or other forms of prior knowledge of the objects.  ...  The selection of threshold is a trade-off problem between false alarm and neglect of objects. A brief discussion of this problem is provided in Section 4.1.  ...

Vessel-guided airway tree segmentation: A voxel classification approach

Pechin Lo, Jon Sporring, Haseem Ashraf, Jesper J.H. Pedersen, Marleen de Bruijne
2010 Medical Image Analysis  
We propose a voxel classification approach for the appearance model, which uses a classifier that is trained to differentiate between airway and non-airway voxels.  ...  A vessel orientation similarity measure is introduced, which indicates how similar the orientation of an airway candidate is to the orientation of the neighboring vessel.  ...  The voxel classification based methods resulted in higher false discovery rate compared to intensity based method, but it must be noted that a slightly higher false discovery rate may actually be desirable  ...
