Method Detail

init

void init(D dataset,
          int stratiAmount)

Initialize custom assigner if necessary.

Parameters:

dataset - The dataset the datapoints will be sampled from.

stratiAmount - The predetermined amount of strati the dataset will be stratified into.

assignToStrati

int assignToStrati(I datapoint)

Custom logic for assigning datapoints into strati.

Parameters:

datapoint - The datapoint that has to be assigned.

Returns:

The index of the strati the datapoint will be assigned into.

setNumCPUs

void setNumCPUs(int numberOfCPUs)

Sets the number of CPU cores that can be used for parallel computation

Parameters:

numberOfCPUs -

getNumCPUs

int getNumCPUs()
