我正在使用Caret的PCI预处理.

multinomFit <- train(LoanStatus~., train, method = "multinom", std=TRUE, family=binomial, metric = "ROC",  thresh = 0.85, verbose = TRUE, pcaComp=7, preProcess=c("center", "scale", "pca"), 
    trControl = ctrl)

我指定,PCA组件的数量为7.为什么摘要显示使用68个组件的拟合？

summary(multinomFit)

Call:
multinom(formula = .outcome ~ ., data = dat, decay = param$decay, 
    std = TRUE, family = ..2, thresh = 0.85, verbose = TRUE, 
    pcaComp = 7)

Coefficients:
                   Values  Std. Err.

我正在尝试在本地模式下运行 Hadoop 命令。我在 Mac OS X 10.10.5 上运行，在将文件放入 HDFS 时出现错误。这是来自我的 Hadoop 命令的错误消息：

 $ sudo hadoop fs -put HG00103.mapped.ILLUMINA.bwa.GBR.low_coverage.20120522.bam /usr/ds/genomics
    Password:
    15/09/25 10:10:50 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
    put: Call From BlueMeanie/10.0.1.5 to localhost:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

以下是我的系统的详细信息：

$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

$ hadoop version …

我运行的是 OS X 10.10.5。我尝试打开终端时遇到错误：

tput：未知终端“xterm-256color”

这显然是缺少 termcap 条目。

$ port list ncurses
ncurses                        @6.0            devel/ncurses

关于如何在 OS X 上安装“ncurses-term”有什么想法吗？

$ sudo port install ncurses-term

Error: Port ncurses-term not found

我正在研究Gradle/Java 1.8/Spring Boot,Spring Integration,Spring Batch,Spring Data Rest项目(我继承了).

这是来自build.gradle的依赖项

// Spring Boot
compile("org.springframework.boot:spring-boot-starter-ws")
compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.boot:spring-boot-starter-integration")
compile("org.springframework.boot:spring-boot-starter-actuator")
compile("org.springframework.boot:spring-boot-starter-security")
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile("org.springframework.boot:spring-boot-starter-batch")

// Spring integration
compile("org.springframework.integration:spring-integration-core")
compile("org.springframework.integration:spring-integration-ws")
compile("org.springframework.integration:spring-integration-jpa")
compile("org.springframework.integration:spring-integration-sftp")

// Spring batch
compile("org.springframework.batch:spring-batch-core")
compile("org.springframework.batch:spring-batch-integration")

// Spring Data REST
compile("org.springframework.data:spring-data-rest-webmvc")

查看应用程序的DEBUG日志,我看到两个线程:

i. [http-nio-8080-exec-1],
ii [[http-nio-8080-exec-2]

第一个调用AnonymousAuthenticationToken并且在@ 15:02:56.731中失败:

org.springframework.security.authentication.AnonymousAuthenticationToken

几毫秒后@ 15:02:56.747第二个成功:org.springframework.security.authentication.UsernamePasswordAuthenticationToken

例如

15:02:56.731 [http-nio-8080-exec-1] DEBUG o.s.s.w.a.i.FilterSecurityInterceptor - Previously Authenticated: org.springframework.security.authentication.AnonymousAuthenticationToken@9055e4a6: Principal: anonymousUser; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@957e: RemoteIpAddress: 127.0.0.1; SessionId: null; Granted Authorities: ROLE_ANONYMOUS
