.. 🎯 What We Can Do
.. -----------------

.. .. image:: ./logo/demo_result.png
..    :width: 600

.. **dnn-inference** is able to provide an asymptotically valid `p-value` to examine if :math:`\mathcal{S}` is discriminative features to predict :math:`Y`.
.. Specifically, the proposed testing is:


..    H_0: R(f^*) - R_{\mathcal{S}}(g^*) = 0, \quad \text{versus} \quad H_a: R(f^*) - R_{\mathcal{S}}(g^*) < 0,


.. where :math:`\mathcal{S}` is a collection of hypothesized features, 
.. :math:`R` and :math:`R_{\mathcal{S}}` are risk functions with/without the hypothesized features :math:`\mathbf{X}_{\mathcal{S}}`, 
.. and :math:`f^*` and :math:`g^*` are population minimizers on :math:`R` and :math:`R_{\mathcal{S}}` respectively. 
.. The proposed test just considers the difference between the best predictive scores with/without hypothesized features. 
.. Please check more details in our paper `arXiv:2103.04985 <https://arxiv.org/abs/2103.04985>`_.

.. - When `log-likelihood` is used as a loss function, then the test is equivalent to a conditional independence test: :math:`Y \perp X_{\mathcal{S}} | X_{\mathcal{S}^c}`. 
.. - Only `a small number of fitting` on neural networks is required, and the number can be as small as 1.
.. - Asymptotically Type I error control and power consistency.
