Sam Greydanus: My most recent @GoogleAI residency project is out: "Hamiltonian Neural Networks" Blog: https://greydanus.github.io/2019/05/15/hamiltonian-nns/ Paper: https://arxiv.org/abs/1906.01563 Starting from noisy (pixel) data, we can learn _exact_ conservation of energy-like quantities. https://t.co/SY2jZBr5an

Alfredo Canziani: «Hamiltonian NN» uses a physical invariance (conservation of total energy) to reduce the variance of NN and get better generalisation for physical systems by training the net's *input gradients*! This, coupled with an (why not convolutional?) AE can be used directly on pixels!!! https://t.co/yqyD3U8bDu

John Platt: You can create a recurrent neural network out of a symplectic integration of a Hamiltonian, which learns physics from noisy examples. http://arxiv.org/abs/1909.13334 HT Leon Bottou at #NeurIPS . Based on http://arxiv.org/abs/1906.01563 by @samgreydanus

Daisuke Okanohara: Hamiltonian Neural Network uses Hamiltonian mechanics as inductive bias and learns a Hamiltonian-like scalar function in an unsupervised manner, s.t the dynamics follow the gradients of the learned scalar function. Trains faster and generalizes better https://arxiv.org/abs/1906.01563
