A hierarchical case representation using context guided retrieval

Ian Watson, Srinath Perera
1998 Knowledge-Based Systems  
Problems are decomposed into sub-problems and solutions recomposed into a final solution.  ...  This paper presents a hierarchical case representation using a context guided retrieval method.  ...  As the problem space increases, from say a 20 dimensional space to a 200 dimensional space it becomes statistically less likely that a close matching case will exist.  ...

Review of methods for space–time disease surveillance

Colin Robertson, Trisalyn A. Nelson, Ying C. MacNab, Andrew B. Lawson
2010 Spatial and Spatio-temporal Epidemiology  
Methods are classified as testing-based or model-based approaches.  ...  A review of some methods for analysis of space-time disease surveillance data is presented.  ...  The scale and scope of the surveillance context does not limit a model-based approach, and models may be even more useful when data abnormalities such as time lags occur (as estimates can be based on covariates  ...

Improvements in Sub-character HMM Model Based Arabic Text Recognition

Irfan Ahmad, Gernot A. Fink, Sabri A. Mahmoud
2014 2014 14th International Conference on Frontiers in Handwriting Recognition  
In the current paper we are presenting our recent improvements in sub-character HMM modeling for Arabic text recognition where we use special 'connector' and 'space' models.  ...  Additionally we investigated contextual sub-characters HMMs for text recognition.  ...  Further they experimented with context-dependent sub-stroke models to capture the variation of sub-strokes due to its context (its adjacent sub-strokes).  ...

Adaptive Context-Tree-Based Statistical Filtering for Raster Map Image Denoising

Minjie Chen, Mantao Xu, Pasi Franti
2011 IEEE transactions on multimedia  
Index Terms-Context-tree modeling, raster map image, statistical filtering.  ...  We apply a universal statistical filter using context-tree modeling via a selective context expansion capturing those pixel combinations that are present in the image.  ...  For each context , we first construct a set of sub-contexts: ality, we sum up all the vectors of statistics of the sub-contexts as the estimated distribution of the original context if the frequency of  ...

A Smart Home Context-aware Model Based On UML and Colored Petri Net

Xiaopeng Niu, Zhiliang Wang
2016 International Journal of Smart Home  
To address this issue, we propose a hybrid Context-aware Modeling approach based on UML and Colored Petri Net in this paper.  ...  As context information is obtained from different sources in the Smart Home environment, the context information may be heterogeneous, inaccurate and dynamic.  ...  The State Space Statistics of the State Space Report are listed in Table 4.  ...

Free-gram phrase identification for modeling Chinese text

Xi Peng, Zhang Yi, Xiao-Yong Wei, De-Zhong Peng, Yong-Sheng Sang
2013 Information Processing Letters  
In the proposed method, we first convert each document into a context graph, a directed graph that encapsulates the statistical and positional information of all the 2-word strings in the document.  ...  Finally, we selectively divide some of the complex candidate phrases into sub-phrases to improve the coding efficiency, resulting in a set of phrases for codebook construction.  ...  The rationale of the phrase splitting is based on the fact that sub-dividing a complex pattern into several sub-patterns that are also statistically significant can increase the entropy of the coding scheme  ...

Maha Alamri, William Teahan
2019 Computers  
The system uses a language model based on the Prediction by Partial Matching (PPM) text compression scheme that generates possible alternatives for each misspelled word.  ...  Furthermore, the generated candidate list is based on edit operations (insertion, deletion, substitution and transposition), and the correct alternative for each misspelled word is chosen on the basis  ...  The first sub-stage (2a) uses a statistical model to correct dyslexic errors according to their context based on the dyslexic error classification for Arabic texts (DECA) [11] .  ...

2016 arXiv   pre-print
We propose an efficient graph-based matching algorithm, integrated with hash-based indexing, to prune a possibly large search space.  ...  A user can specify a combination of sub-layouts of interest using sketch-based queries. The system supports partial matching for unspecified layout entities.  ...  This section shows the use of context information as a feature for hash-based indexing for pruning the plausibly large search space.  ...

2009 Photogrammetric Engineering and Remote Sensing  
Currently, classifiers are evaluated through human input using an expert-based system; therefore, this paper acts as the proof of concept for collaborative classifiers.  ...  Because we decompose the problem into smaller, more manageable sub-tasks, our classification exhibits increased flexibility compared to existing methods since classification methods are tailored to the  ...  Simulation Speed We reserve the computationally expensive inputs (e.g., texture-based statistics) only for sub-tasks where conventional statistics (e.g., normalized band differences) do not provide adequate  ...
