Injective Domain Knowledge in Neural Networks for Transprecision Computing
Machine Learning (ML) models are very effective in many learning tasks, due
to the capability to extract meaningful information from large data sets.
Nevertheless, there are learning problems that cannot be easily solved relying
on pure data, e.g. scarce data or very complex functions to be approximated.
Fortunately, in many contexts domain knowledge is explicitly available and can
be used to train better ML models. This paper studies the improvements that can
be obtained by integrating prior knowledge when dealing with a non-trivial
learning task, namely precision tuning of transprecision computing
applications. The domain information is injected in the ML models in different
ways: I) additional features, II) ad-hoc graph-based network topology, III)
regularization schemes. The results clearly show that ML models exploiting
problem-specific information outperform the purely data-driven ones, with an
average accuracy improvement around 38%
