Struct ChunkedOptimizer

Source

pub struct ChunkedOptimizer<O, A>where
    O: Optimizer<A, Ix1> + Clone,
    A: Float + ScalarOperand + Debug,
{ /* private fields */ }

Expand description

Chunked optimizer for processing large parameter arrays in chunks

Enables optimization of very large models by processing parameters in manageable chunks, reducing peak memory usage.

Implementations§

Source §

impl<O, A> ChunkedOptimizer<O, A>
where O: Optimizer<A, Ix1> + Clone, A: Float + ScalarOperand + Debug,

Source

pub fn new(base_optimizer: O, chunk_size: Option<usize>) -> Self

Creates a new chunked optimizer

§Arguments

base_optimizer - Base optimizer to use for each chunk
chunk_size - Size of each chunk (default: 1M elements)

Source

pub fn step_chunked( &mut self, params: &Array1<A>, gradients: &Array1<A>, ) -> Result<Array1<A>>

Process parameters in chunks

§Arguments

params - Full parameter array
gradients - Full gradient array

§Returns

Updated parameters

Source

pub fn chunk_size(&self) -> usize

Get the chunk size

Source

pub fn num_chunks(&self, total_size: usize) -> usize

Calculate number of chunks for given size
