.. _dag_examples: Data Transformation Examples ============================ This page provides examples of :ref:`data processing ` via the :ref:`data transformation framework `. All examples are tested. .. contents:: :local: :depth: 2 ---- Curve Fitting ------------- For fitting a curve to some data, the following operations can be combined: * The ``lambda`` operation to define the model function, see :py:func:`~dantro.data_ops.expr_ops.generate_lambda` * The ``curve_fit`` operation, which is an alias for ``scipy.optimize.curve_fit``; see `scipy documentation `_ .. literalinclude:: ../../tests/cfg/dag.yml :language: yaml :start-after: ### Start -- dag_examples_curve_fitting :end-before: ### End ---- dag_examples_curve_fitting :dedent: 4 .. note:: The polynomial above of course doesn't *quite* achieve fitting an elephant to the data, as John von Neumann wanted to show. However, see `this blog post `_ on how this can actually be achieved.
