Deep Learning for Bayesian Optimization of Scientific Problems with High-Dimensional Structure

2 code implementations23 Apr 2021 Samuel Kim, Peter Y. Lu, Charlotte Loh, Jamie Smith, Jasper Snoek, Marin Soljačić

Bayesian optimization (BO) is a popular paradigm for global optimization of expensive black-box functions, but there are many domains where the function is not completely a black-box.

OccamNet: A Fast Neural Model for Symbolic Regression at Scale

4 code implementations16 Jul 2020 Owen Dugan, Rumen Dangovski, Allan Costa, Samuel Kim, Pawan Goyal, Joseph Jacobson, Marin Soljačić

Neural networks' expressiveness comes at the cost of complex, black-box models that often extrapolate poorly beyond the domain of the training dataset, conflicting with the goal of finding compact analytic expressions to describe scientific data.

Integration of Neural Network-Based Symbolic Regression in Deep Learning for Scientific Discovery

1 code implementation10 Dec 2019 Samuel Kim, Peter Y. Lu, Srijon Mukherjee, Michael Gilbert, Li Jing, Vladimir Čeperić, Marin Soljačić

We find that the EQL-based architecture can extrapolate quite well outside of the training data set compared to a standard neural network-based architecture, paving the way for deep learning to be applied in scientific exploration and discovery.

Extracting Interpretable Physical Parameters from Spatiotemporal Systems using Unsupervised Learning

1 code implementation13 Jul 2019 Peter Y. Lu, Samuel Kim, Marin Soljačić

Our method for discovering interpretable latent parameters in spatiotemporal systems will allow us to better analyze and understand real-world phenomena and datasets, which often have unknown and uncontrolled variables that alter the system dynamics and cause varying behaviors that are difficult to disentangle.

Syntactical Analysis of the Weaknesses of Sentiment Analyzers
