coco_pipe.dim_reduction.reducers.base
=====================================

.. py:module:: coco_pipe.dim_reduction.reducers.base

.. autoapi-nested-parse::

   Base interfaces for dimensionality reduction backends.

   This module defines the reducer contract shared by built-in reducers and
   user-defined reducers. A reducer is any object derived from
   `~coco_pipe.dim_reduction.reducers.base.BaseReducer` implementing `fit` and `transform`
   , optionally exposing diagnostics and scalar quality metadata through helper methods.

   The surrounding dim-reduction stack uses these interfaces to provide:

   - input validation through the reducer `capabilities` mapping
   - standardized persistence with `save` and `load`
   - reducer-aware reporting and visualization hooks
   - optional dependency loading through `coco_pipe.utils.import_optional_dependency`

   .. rubric:: Notes

   `~coco_pipe.dim_reduction.reducers.base.BaseReducer` is the intended extension point for
   custom reducers. Third-party reducers can participate in
   `~coco_pipe.dim_reduction.DimReduction` workflows without extra wrappers as long as they
   respect the method contract documented here.
