As artificial intelligence increasingly drives
critical decisions, the ability to genuinely
explain how neural networks make predictions is
essential for trust. Yet, most current explanation
methods offer post-hoc rationalizations rather
than guaranteeing a true reflection of the model's
reasoning. We introduce the notion of explanatory
alignment, a requirement that explanations
directly construct predictions rather than
rationalize them. To achieve this in complex data
domains, we present Pointwise-interpretable
Networks (PiNets), a pseudo-linear architecture
that forms linear models instance-wise. Evaluated
on image classification and segmentation tasks,
PiNets demonstrate that their explanations are
deeply faithful across four criteria:
meaningfulness, alignment, robustness, and
sufficiency (MARS). Our contributions pave the way
for promising avenues: by reconciling the
predictive power of deep learning with the
interpretability of linear models, PiNets provide
a principled foundation for trustworthy AI and
data-driven scientific discovery.
