Struct BlockedTemporalSplit 

pub struct BlockedTemporalSplit {
    pub series_len: usize,
    pub block_len: usize,
    pub train_blocks: Arc<[TimeRange]>,
    pub test_blocks: Arc<[TimeRange]>,
    pub rows: RowSplit,
    pub seed: u64,
}

Blocked temporal split: contiguous time blocks assigned to train / test.

Fields

series_len: usize

Series length.

block_len: usize

Block length in rows.

train_blocks: Arc<[TimeRange]>

Training blocks as ranges.

test_blocks: Arc<[TimeRange]>

Test blocks as ranges.

rows: RowSplit

Flattened row partition.

seed: u64

Seed.

Implementations

impl BlockedTemporalSplit

pub fn try_new( series_len: usize, block_len: usize, test_frac: f64, seed: u64, ) -> Result<Self, DataError>

Partition 0..series_len into blocks of block_len and assign by shuffle.

The final block may be shorter. At least one train and one test block required.

Errors

Invalid sizes / fraction.
