Feature selection is the process of minimizing the number of features in a dataset and making the model as compact as possible. It could be divided into three methods: wrapper, embedded, and filter method [8,9]. Wrapper and embedded methods are more efficient than the filter method but are...
Additionally, as a validation of the classification techniques, the dataset was subjected to five-fold cross-validation and independent sample set splitting (80% calibration and 20% validation). Evaluation metrics such as accuracy, F score, and G mean were used to evaluate prediction performance. ...
of noise reduction through the application of the Savitzky–Golay smoothing filter (13-point window size), SAM (spectral angle mapping) supervised image classification was performed using ENVI 5.0 + IDL software to gain additional insights into the spatial distribution of materials within the dataset....
Ca in a 464 km2 regional scale dataset with the samples at the interval of 0 – 0.2 m (318 samples), 0.4 – 0.6 m (317 samples), and 0.8 – 1.0 m (291 samples). A random validation subset was selected for each dataset and SVM was used for modelling. In addition, 38 different ...
(AUS, IND, TRJ, TEJ, and ARO). It has been re-sequenced to an average depth of 1.5×8and has a filtered genomic dataset of 3.2 million single nucleotide polymorphic (SNP) markers8,12. Therefore, it is an excellent genetic resource to identify chromosomal regions associated with various ...
