我正在处理不平衡的数据集。我正在尝试借助class_weights
建立模型。因此,我可以在什么基础上确定class_weights
。
标签及其数量如下:
label Count
2 47213
3 2096
4 2021
1 737
0 176
那么我应该给class_weight
变量赋什么值:
model.fit(X_train, Y_train, nb_epoch=5, batch_size=32, class_weight=class_weight)
答案 0 :(得分:2)
您可以为此雇用import org.junit.*;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import java.util.concurrent.TimeUnit;
import java.net.URL;
import io.appium.java_client.windows.WindowsDriver;
private static WindowsDriver CalculatorSession = null;
private static WebElement CalculatorResult = null;
@BeforeClass
public static void setup() {
try {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("app", "Microsoft.WindowsCalculator_8wekyb3d8bbwe!App");
CalculatorSession = new WindowsDriver(new URL("http://127.0.0.1:4723"), capabilities);
CalculatorSession.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
CalculatorResult = CalculatorSession.findElementByAccessibilityId("CalculatorResults");
Assert.assertNotNull(CalculatorResult);
}catch(Exception e){
e.printStackTrace();
} finally {
}
}
中的compute_class_weight
。
