Up until now, we are basically just read in raw data. Luckily, Spark ML has quite a few preprocessing features available, so the only thing we'll ever have to does is define TR Ansformations of data frames.
To proceed, we'll transform category strings to double values. This are done by the a so called stringindexer. Note this we carry out o

A typical machine learning machine learning process typically includes: source data ETL, data preprocessing, index extraction, model training and cross-validation, new data prediction, etc. We can see that this is a pipelined work with multiple steps, that is, the data starts from the collection and goes
as follows:
Var moviesThatNeedBetterWriters = new Array ('Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4');
A more concise statement is as follows:
The Code is as follows:
Var moviesThatNeedBetterWriters = ['Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4'];
For arrays, there is also a special thing like associating arrays. You will find that many codes define objects as foll
= new Array ('Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4');
Use the simple statement:
The Code is as follows:
Var moviesThatNeedBetterWriters = ['Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4'];
Another question about arrays is whether there is an associated array. You will find a lot of code examples to define examples like this on the car
The Code is as follows:

It is very simple to define objects and arrays in JavaScript. We want to create an object, which is generally written as follows:
varcar=newObject();
car.colour='red';
car.wheels=4;
car.hubcaps='spinning';
car.age=4;
The following statement can achieve the same effect:
varcar={
colour:'red',
wheels:4,
hubcaps:'spinning',
age:4
}
The subsequent statement is much shorter, and you do not need to repeat the object name.
In addition, there
Concise notationOne of my favorite things in JavaScript is the shorthand method for generating objects and arrays. In the past, if you wanted to create an object, you needed this:1 var car = new Object (), 2 car.colour = ' red '; 3 Car.wheels = 4;4 car.hubcaps = ' spinning '; 5 car.age = 4;The following writing can achieve the same effect:1 var car = {2 colour: ' Red ', 3 wheels:4,4 hubcaps: ' Spinning ', 5 age:46}It's much simpler, you don't have to use the name of the object repeatedly. So car
may encounter invalidUserInSession, which only happens when you use IE. Remember that you don't need to write a comma in front of the right braces, so you won't be in trouble.
Another convenient shorthand is for arrays. The traditional method for defining arrays is as follows:Copy codeThe Code is as follows:Var moviesThatNeedBetterWriters = new Array ('Transformers ', 'transformers2', 'Avatar', 'indianajones 4');The short version is as follows:Copy c
. You don't need to use the name of this object repeatedly. In this way, the car is defined, and you may encounter invalidUserInSession, which only happens when you use IE. Remember that you don't need to write a comma in front of the right braces, so you won't be in trouble.
