To check if the class contains only lowercase chars, digits or - you could use a negative lookahead to assert not that format.

If the assertion is true, you can match all till the closing "

When using transformes (TfidfVectorizer in this case), you must use the same object ot transform both train and test data. The transformer is typically fitted using the training data only, and then re-used to transform the test data.

The correct way to do this in your case:

UML Which arrow to connect concrete class and its abstract class?

Asked 2020-Oct-07 at 00:02

Here, in the only answer, it's a simple arrow: How to present an abstract class in UML class diagram

But here, it's similar to the interface arrow: http://www.cems.uwe.ac.uk/~jsa/UMLJavaShortCourse09/CGOutput/Unit9/unit9(0809)/page_03.htm

I'm thinking it should be the same arrow as class to interface arrow of the diagram; is that right?

ANSWER

Answered 2020-Oct-06 at 23:44

No. The picture you reference shows a generalization. In that case the three concrete classes below just inherit from the abstract class on top. The isAbstract property of the top class just tells that you can not instantiate it directly. You must derive concrete classes (which inherit attributes/operations).

The assocation in the referenced answer just tells that the concrete class Structure deals with concrete classes derived from Contexte. You see three generalizations to the right which for sure will be those concrete classes.

N.B. Inheriting from an abstract class is "similar" to realizing an interface.

Issue/Bug when loading and applying MultilayerPerceptronClassifier in Spark Version 3.0.0

Asked 2020-Jul-14 at 14:11

IllegalArgumentException: MultilayerPerceptronClassifier_... parameter solver given invalid value auto

I believe I have discovered a bug when loading MultilayerPerceptronClassificationModel in spark 3.0.0, scala 2.1.2 which I have tested and can see is not there in at least Spark 2.4.3, Scala 2.11. .

I am using pyspark on a databricks cluster and importing the library “from pyspark.ml.classification import MultilayerPerceptronClassificationModel”

When running model=MultilayerPerceptronClassificationModel.(“load”) and then model. transform (df) I get the following error: IllegalArgumentException: MultilayerPerceptronClassifier_8055d1368e78 parameter solver given invalid value auto.

This issue can be easily replicated by running the example given on the spark documents: http://spark.apache.org/docs/latest/ml-classification-regression.html#multilayer-perceptron-classifier

Then adding a save model, load model and transform statement as such:

How to load dataset from String in spark

Asked 2020-May-18 at 12:13

From spark's document, I know I can load from a libsvm-formatted dataset from file.

However, I want to run codes in a remote spark cluster, so I hard coded the iris dataset into my code, and I want to directly load from this String object.

However, when looking into the DataFrameReader object, I find there is no API which supports direct loading dataset from String.

In your angular.json the order of scripts to include in the build is wrong.

joint.shapes.uml.js should be executed after joint.js is executed.

Is there a way to use knitr's css class options when using kable tables?

Asked 2020-Jan-24 at 17:04

I recently read about knitr's css classes for chunks as discussed in this question and this example.

In general, this seems to work great. The trouble I'm having is that these options no longer seem to work if the output you're using is a kable. The example below illustrates what I'm talking about. In the first two chunks, I'm able to successfully add the css class bg-success to my output, but the third chunk does not apply this.
