# RandomSplit
|
||
|
|
|
||
|
|
One of the simplest methods from Cross-validation is implemented as `RandomSpilt` class. Samples are split to two groups: train group and test group. You can adjust number of samples in each group.
|
||
|
|
|
||
|
|
### Constructor Parameters
|
||
|
|
|
||
|
|
* $dataset - object that implements `Dataset` interface
|
||
|
|
* $testSize - a fraction of test split (float, from 0 to 1, default: 0.3)
|
||
|
|
* $seed - seed for random generator (for tests)
|
||
|
|
|
||
|
|
```
|
||
|
|
$randomSplit = new RandomSplit($dataset, 0.2);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Samples and labels groups
|
||
|
|
|
||
|
|
To get samples or labels from test and train group you can use getters:
|
||
|
|
|
||
|
|
```
|
||
|
|
$dataset = new RandomSplit($dataset, 0.3, 1234);
|
||
|
|
|
||
|
|
// train group
|
||
|
|
$dataset->getTrainSamples();
|
||
|
|
$dataset->getTrainLabels();
|
||
|
|
|
||
|
|
// test group
|
||
|
|
$dataset->getTestSamples();
|
||
|
|
$dataset->getTestLabels();
|
||
|
|
```
