Data mining is extraction of data from large datasets and converts it into useful information. Extracting the labeled data it is most difficult one, for this various techniques implemented for this extracting the labeled data. In machine learning, extracting thelabeled data from large dataset is ...

The segmentation performance of the proposed model is evaluated on two public datasets (ISIC2018 and PH2) and a private dataset. Compared to U-Net, the proposed model achieves an IoU improvement of 0.0261 points and a DSC improvement of 0.0164 points, while reducing the parameter count by 190...
(b) The RD imaging result of the dataset. Next, we add a translational error for the dataset. We set R 0 = 5 k m , V = 500 m / s and θ 0 = 2 ° , the expression of the translational motion added in the dataset is the same as (5). The range profile of the dataset ...

# minimally prepare dataset X = X.astype('float32') y = LabelEncoder().fit_transform(y.astype('str')) #split the dataset from sklearn.model_selection import train_test_split X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.2, random_state = 0) ...
Finally, the data enhancement is carried out by affine transformation and motion blur processing of the dataset, which improves the robustness of the model for long-distance and vibration environment detection. The experimental results show that in the comparison model, GSC-YOLO has the smallest ...
Grayscale color images are acquired from a charge-coupled device (CCD) camera, assembling a dataset of 500 matrix images samples for the character digits from 0 to 9. The GSC feature extraction method is applied to get the characteristics that will be used in the character recognition step. ...
On this dataset, the software was shown to achieve an error rate of around 1% at genus level. Examples of applications based on the nitrogenase subunit NifH gene and a protein-coding gene found in endospore-forming Firmicutes is also presented. The programs in the package have a simple, ...
Experiments on the BrainWeb18 dataset and the Internet Brain Segmentation Repository 18 dataset validate the superiority of our scheme compared with approaches based on a single feature type, and some other state-of-the-art methods. The ablation experiment indicates that the proposed GSCFN can ...
