function RandomSampler¶

explicit RandomSampler(
    size_t dataset_size,
    std::optional< uint64_t > seed =std::nullopt
)

Parameters:

• dataset_size Number of samples to shuffle.
• seed Optional RNG seed; falls back to the default generator.

Create a sampler that shuffles dataset_size indices with an optional fixed seed.

function Indices¶

virtual std::vector< size_t > Indices() const override

Return:

• Shuffled indices.
• Randomly ordered index list.

Reimplements: tenzr::data::Sampler::Indices

Return a shuffled permutation of 0..size-1.

function Size¶

inline virtual size_t Size() const override

Return: Number of indices.
