How to Incorporate Monotonicity in Deep Networks While Preserving Flexibility?

1 code implementation24 Sep 2019 Akhil Gupta, Naman Shukla, Lavanya Marla, Arinbjörn Kolbeinsson, Kartik Yellepeddi

We focus on incorporating monotonic trends, and propose a novel gradient-based point-wise loss function for enforcing partial monotonicity with deep neural networks.

Tensor Dropout for Robust Learning

no code implementations27 Feb 2019 Arinbjörn Kolbeinsson, Jean Kossaifi, Yannis Panagakis, Adrian Bulat, Anima Anandkumar, Ioanna Tzoulaki, Paul Matthews

CNNs achieve remarkable performance by leveraging deep, over-parametrized architectures, trained on large datasets.
