Module middleware 

Middleware system for kernel approximation pipelines

This module provides a flexible middleware architecture for composing kernel approximation transformations with hooks, callbacks, and monitoring.

Examples

use sklears_kernel_approximation::middleware::{Pipeline, PipelineBuilder};
// Create a pipeline with multiple transformations
// let pipeline = PipelineBuilder::new()
//     .add_transform(rbf_sampler)
//     .add_hook(logging_hook)
//     .add_middleware(normalization_middleware)
//     .build();
