There are four types relics according whether they weathered. Through evaluation principal component anal...

Underwater source localization is an important task, especially for real-time operation. Recently, machine learning methods have been combined with supervised schemes. This opens new possibilities underwater localization. However, in many real scenarios, the number of labeled datasets insufficient purely learning, and training time a deep neural network can be huge. To mitigate problem related ...

Adopt principal component regression for researching the optimal subsidy mode of cotton production in China.
