Reliability-Based Feature Weighting for Automated Essay Scoring

Yigal Attali
2014 Applied Psychological Measurement  
The article shows, in the context of a large-scale writing assessment, that these alternative weighting schemes are significantly different from human-prediction weights and give rise to comparable or  ...  However, it is evident that machine evaluation of essays is fundamentally different from human evaluation and therefore is not likely to measure the same set of writing skills.  ...  In evaluating the importance of differences in correlation coefficients for Research Questions 2 and 3, one should remember that the scores obtained from different weighting schemes are not independent  ...

Computational Complexity and Peak-to-Average Power Ratio Reduction of OFDM Signals by PTS with Sub optimum Grouping Phase Weighting Method

Prashant Pandey, Rajeev Tripathi
2013 International Journal of Computer Applications  
However optimum PTS (OPTS) needs exhaustive search over all combinations of allowed phase weighting factors. It results in high computational complexity.  ...  In this paper we propose a novel technique known as Sub-optimum Grouping Phase Weighting (S-GPW) Method which not only reduces the computational complexity but also have an advantage of increment in PAPR  ...  In the process of phase weighting combination, large number of complex multiplications are needed and hence the computational complexity is very large.  ...

Locally-adaptive similarity metric for deformable medical image registration

Lisa Tang, Alfred Hero, Ghassan Hamarneh
2012 2012 9th IEEE International Symposium on Biomedical Imaging (ISBI)  
Different parts of a medical image, however, may contain significantly different appearance properties such that a metric may only be applicable in certain image regions but less so in other regions.  ...  More and more researchers are beginning to use multiple dissimilarity metrics or image features for medical image registration.  ...  Evidently, while both the equal and weighted schemes achieved similar DSC scores, the former scheme gave much higher TRE scores than those achieved by the weighted scheme.  ...
