AttributeError when using ColumnTransformer into a pipeline

百般思念 提交于 2019-12-05 21:39:34
This is my first machine learning project and the first time that I use ColumnTransformer. My aim is to perform two steps of data preprocessing, and use ColumnTransformer for each of them. In the first step, I want to replace the missing values in my dataframe with the string 'missing_value' for some features, and the most frequent value for the remaining features. Therefore, I combine these two operations using ColumnTransformer and passing to it the corresponding columns of my dataframe. In the second step, I want to use the just preprocessed data and apply OrdinalEncoder or OneHotEncoder

Saxon 9.2 / Java / XSLT: setting transformer parameters using setParameters()

I have the following XSLT 2.0 template: <xsl:template name="t1"> <xsl:variable name="totalpos" as="xsd:double" select="$currentTotal"/> .. I am struggling to programmatticaly provide currentTotal as a parameter to the transformer, like this: transformer.setParameter("currentTotal", new Double("100")) .. but without any positive results: Error at /xsl:transform/xsl:template[3]/xsl:variable[1] XPST0008: XPath syntax error at char 13 on line -1 in {$currentTotal}: Variable $currentTotal has not been declared When calling setParameter() , the currentTotal variable will also get defined, right? How

RxJava(八)Disposable和Transformer

Disposable和Transformer 一,Disposable 1.当Observable发送数据,Observer订阅数据时,就形成一个Disposable,可用于在退出时取消订阅。 Disposable disposable = Observable . just ( 1 , 2 , 3 ) . subscribeOn ( Schedulers . newThread ( ) ) . observeOn ( AndroidSchedulers . mainThread ( ) ) . map ( new Function < Integer , Integer > ( ) { @Override public Integer apply ( Integer integer ) { return integer + 1 ; } } ) . subscribe ( new Consumer < Integer > ( ) { @Override public void accept ( Integer integer ) throws Exception { } } ) ; } 2.CompositeDisposable 一个复合订阅容器,用于管理所有的Disposable,方便在退出时取消订阅,避免内存溢出。 通常写在BaseActivity中。

Save custom transformers in pyspark

血红的双手。 提交于 2019-12-01 11:55:36
When I implement this part of this python code in Azure Databricks: class clustomTransformations(Transformer): <code> custom_transformer = customTransformations() .... pipeline = Pipeline(stages=[custom_transformer, assembler, scaler, rf]) pipeline_model = pipeline.fit(sample_data) pipeline_model.save(<your path>) When I attempt to save the pipeline, I get this: AttributeError: 'customTransformations' object has no attribute '_to_java' Any work arounds? dportman It seems like there is no easy workaround but to try and implement the _to_java method, as is suggested here for StopWordsRemover:

gcc ON arm/android

I just got a EEE pad transformer. Like any hardware I own I'd like to have a C compiler on it. I know I can cross compile, but I'd like to do development ON the device itself. I've searched google and all I can seem to find are pages on how to build an arm toolchain for x86/64 Linux. Thoughts? The process of building gcc (et al.) to run on your target should be similar to building a cross-compiler, excepting that you will: need to have an ARM cross compiler that runs on your, for example, x86 machine. So the results of your googleing are still useful. use the --host option to specify your ARM

The “touchmove” event on android system: Transformer Prime

回眸只為那壹抹淺笑 提交于 2019-11-28 21:30:24
I am working on a Transformer Pad and developing a drawing plate. I use PhoneGap(javascript) to write the code instead of JAVA. But the touchmove event is quite weird. I think as I move my finger on the pad, it will continuously to collect the coordinates which I touch on the canvas. BUT IT DOES NOT! It's ridiculous, it only collect "1" coordinate: the first point on the canvas my finger moves to. Here are my code about the "Touch && Move event": function touchStart(event){ if (event.targetTouches.length == 1) { var touch = event.targetTouches[0]; if (event.type == "touchstart") { line_start_x
