Examples of edu.ucla.sspace.index.RandomIndexVectorGenerator

edu.ucla.sspace.index.RandomIndexVectorGenerator
An class that generates {@link RandomTernaryVector} instances based onconfigurable properties. This class supports two properties:

Property: {@value #VALUES_TO_SET_PROPERTY}
Default: {@value #DEFAULT_INDEX_VECTOR_VALUES}
This variable sets the number of bits to set in an index vector.

Property: {@value #INDEX_VECTOR_VARIANCE_PROPERTY}
Default: {@value #DEFAULT_INDEX_VECTOR_VARIANCE}
This variable sets the variance in the number of bits to set in an index vector. For example, having {@value #VALUES_TO_SET_PROPERTY}{@code =4} and setting this property to {@code 2} would mean that {@code 4 ± 2} value would be randomly set ineach index vector.
