Struct fp_growth::algorithm::FPGrowth [−][src]
FPGrowth<T>
represents an algorithm instance, it should include the transactions
input
and minimum support value as the initial config. Once it is created, you could run
FPGrowth::find_frequent_patterns()
to start the frequent pattern mining.
Implementations
impl<T: ItemType> FPGrowth<T>
[src]
pub fn new(transactions: Vec<Vec<T>>, minimum_support: usize) -> FPGrowth<T>
[src]
Create a FP-Growth algorithm instance with the given transactions
and minimum_support
.
pub fn find_frequent_patterns(&self) -> Vec<(Vec<T>, usize)>
[src]
Find frequent patterns in the given transactions using FP-Growth.
