Accuracy Boosters: Epoch-Driven Mixed-Mantissa Block Floating-Point for DNN Training

no code implementations19 Nov 2022 Simla Burcu Harma, Ayan Chakraborty, Babak Falsafi, Martin Jaggi, Yunho Oh

The unprecedented growth in DNN model complexity, size, and amount of training data has led to a commensurate increase in demand for computing and a search for minimal encoding.

Multigoal-oriented dual-weighted-residual error estimation using deep neural networks

no code implementations21 Dec 2021 Ayan Chakraborty, Thomas Wick, Xiaoying Zhuang, Timon Rabczuk

An efficient and easy to implement algorithm is developed to obtain a posteriori error estimate for multiple goal functionals by employing the dual-weighted residual approach, which is followed by the computation of both primal and adjoint solutions using the neural network.
