Solar radiation from reanalysis datasets can be used to estimate solar energy potential in the absence of long-term surface measured data. Comprehensive validation data against short-term measurements is necessary find uncertainties. The evaluation performance seven (ERA-5, MERRA-2, ERA-Interim, JRA-55, NCEP-NCAR, NCEP-DOE, and CFSR) for Balochistan high-quality was performed using statistical analysis. relative mean bias error (rMBE), absolute (rMAE), root square range −4 7%, 8 14%, 16 21%,...

The k -means algorithm is sensitive to the outliers. In this paper, we propose a robust two-stage clustering based on observation point mechanism, which can accurately discover cluster centers without disturbance of first stage, small subset original data set selected nondegenerate points. good representation because it only contains all those points that have higher density and does not include second use find proper as true set. Based these centers, rest are assigned clusters whose closest...

Image captioning by the encoder-decoder framework has shown tremendous advancement in last decade where CNN is mainly used as encoder and LSTM a decoder. Despite such an impressive achievement terms of accuracy simple images, it lacks time complexity space efficiency. In addition to this, case complex images with lot information objects, performance this CNN-LSTM pair downgraded exponentially due lack semantic understanding scenes presented images. Thus, take these issues into consideration,...
